INSTALLATION MANUAL
2 DESCRIPTION
The Residence KIS boilers have a new ACC combustion control system (active combustion
control).
This new control system, developed by Riello, in all circumstances provides functionality, ef-
ciency and low emissions.
The ACC system uses an ionisation sensor immersed in the burner ame, whose information
allows the control board to operate the gas valve that regulates the fuel.
This sophisticated control system provides for the auto adjustment of the combustion, thereby
eliminating the need for an initial calibration
The ACC system can adapt the boiler to operate with different gas compositions, different pipe
lengths and various altitudes (within the design limits).
The ACC system can also perform an auto-diagnostic operation that locks out the burner before
the permitted upper emission limit is exceeded.
Residence KIS is a type C condensing wall-hung boiler to be used for heating and the produc-
tion of domestic hot water.
Depending on the fume discharge accessory used, it is classied in categories B23P; B53P;
C(10)*; C13,C13x; C33,C33x; C43,C43x; C53,C53x; C83,C83x; C93,C93x.
* Currently not available on model 40kW.
In conguration B23P (when installed indoors), the appliance cannot be installed in bedrooms,
bathrooms, showers or where there are open replaces without a proper air ow. The room whe-
re the boiler is installed must have proper ventilation. Detailed requirements for the installation of
the ue, the gas piping and for ventilating the room, can be found in UNI 7129-7131.
In conguration C, the appliance can be installed in any type of room and there are no limitations
due to ventilation conditions or room volume.
3 INSTALLATION
3.1 Cleaning the system and characteristics of the water
In the case of a new installation or replacement of the boiler, it is necessary to clean the heating
system. To ensure the device works well, top up the additives and/or chemical treatments (e.g.
anti-freeze liquids, lming agents, etc.) and check the parameters in the table are within the
values indicated.

ENGLISH
3.4 Installation room
The Residence KIS boiler can be installed in various types of room, as long as the discharge of
the combustion product and the combustion air suction are outside the room itself.
In this case the room does not need any ventilation opening since the Residence KIS boilers
have a combustion circuit that is "airtight" with respect to the installation environment.
b
Consider the clearances necessary to access safety and adjustment devices and to
perform maintenance operations.
b
Check that the electric protection level of the appliance is adapted to the installation
room characteristics.
b
If the boilers are supplied with fuel gas of a specic weight greater than that of the air, the
electric parts will have to be positioned more than 500mm above ground level.
3.5 Installation on appliances that are old or that need to be
updated
When the Residence KIS boiler is installed in old systems or systems being updated, check that:
-The ue is suitable for the temperature of the combustion products with condensation, cal-
culated and built according to Standard, is as straight as possible, airtight, insulated and has
no blockages or narrow sections. It is equipped with appropriate condensate collection and
discharge systems
-The electrical system is installed in compliance with the specic standards and by qualied
personnel
-The fuel supply line and eventual tank (LPG) are made according to specic Standards
-The expansion tank ensures the total absorption of the dilatation of the uid contained in the
system
-The ow rate and head of the circulator are suitable to the characteristics of the system
-The system is washed, cleansed of any mud, build-up, vented and sealed. It is recommended
that a magnetic lter be installed on the system's return line
-The boiler condensate drain system (siphon) is connected and routed to the collection of
"white" water.
3.6 Installation regulations
The installation must be carried out by qualied personnel, in compliance with the following
reference standards: UNI 7129-7131 and CEI 64-8.
Always comply with local standards of the Fire Department, the Gas Company and with possible
municipal dispositions.
POSITION
Residence is a wall-hung boiler for heating and for the production of hot water, that comes in two
categories, depending on the type of installation:
-B23P-B53P boiler type - forced open installation, with ue gas discharge pipe and pick-up of
combustion air from the installation area. If the boiler is not installed outdoors, air intake in the
installation area is compulsory.
-C(10), C13,C13x; C33,C33x; C43,C43x; C53,C53x; C83,C83x, C93,C93x boiler type: ap-
pliance with airtight chamber, with ue gas discharge pipe and pick-up of combustion air from
outside. It does not require an air intake point in the installation area. This type MUST be
installed using concentric pipes, or other types of discharge designed for condensing boilers
with an airtight chamber.
Residence can be installed indoor and outdoor, in a partially protected place (i.e. a place where
the boiler is not exposed to direct contact or inltration of rain, snow or hail) and in compliance
with local and national regulation. The boiler can operate in a temperature range from >0°C to
+60°C.
Residence 25 KIS can also be installed outdoor in the built-in unit.
ANTI-FREEZE SYSTEM
The boiler is tted as standard with an automatic anti-freeze system that activates when the
temperature of the water in the primary circuit falls below 5°C. This system is always active and
provides protection for the boiler up to an air temperature in the installation area of 0°C.
b
To take advantage of this protection (based on burner operation), the boiler must
be able to switch itself on; any lockout condition (for ex. due to a lack of gas or
electrical supply, or the intervention of a safety device) therefore deactivates the
protection.
b
When the boiler is installed in a place where there is a risk of freezing, with out-
side air temperatures below 0 °C, an antifreeze heater kit must be used to protect
the DHW circuit and condensation drain (available on request - see catalog) that
protects the boiler up to -15 °C.
b
The installation of the antifreeze heater kit must be carried out only by authorized
personnel, following the instructions contained in the kit.
In normal operating conditions, the boiler can protect itself against frost.
If the machine is left without power for long periods in areas where temperatures may fall below
0°C, and you do not want to drain the heating system, you are advised to add a specic, good
quality antifreeze liquid to the primary circuit. Carefully follow the manufacturer's instructions with
regards not only the percentage of antifreeze liquid to be used for the minimum temperature at
which you want to keep the machine circuit, but also the duration and disposal of the liquid itself.
For the hot domestic water part, we recommend you drain the circuit.
The boiler component materials are resistant to ethylene glycol based antifreeze liquids.
MINIMUM DISTANCES (Fig. 8a-8b)
To ensure access to the boiler for normal maintenance operations, respect the minimum instal-
lation clearances envisaged.
For correct appliance positioning, bear in mind that:
-it must not be placed above a cooker or other cooking device
-it is forbidden to leave inammable products in the room where the boiler is installed
-heat-sensitive walls (e.g. wooden walls) must be protected with proper insulation.
b
When installing it is ABSOLUTELY NECESSARY to provide the spaces necessary for
the introduction of the instrument for analysing the combustion. We have provided a
sample diagram where the distances between the boiler and wall unit /recess have been
obtained using an instrument with a length of 300 mm. Longer instruments require more
space.
3.7 Installation of condensate drain pipe (Fig. 9)
b
Before starting the boiler, even just temporarily, the SRD device supplied must be instal-
led.The manufacturer does NOT accept liability for damage to persons or objects caused
by the boiler operating without the SRD device being installed correctly.
For the installation proceed as follows:
-remove the plug (T) from the siphon
-x the SRD device to the siphon, placing the gasket in-between, screwing it on all the way
and checking its seal
-connect the condensate discharge pipe supplied as standard with the product, then drain the
condensate into a suitable drainage system in compliance with current norms.
b
If it is not possible to t the SRD device due to the interference with other objects under
the boiler, it is possible to t it in a different position by inserting a connecting pipe
between the SRD device and the siphon in order to provide a fully airtight seal. The SRD
device should always be positioned VERTICALLY in order to ensure it functions correctly
3.8 Instruction for condensation exhaust connection

This product is designed to prevent the escape of gaseous products of combustion through the
condensation drain pipe with which it is equipped, this is obtained by using a special siphon
placed inside the appliance.
b
All components of the product condensation drain system must be properly maintained
in accordance with the manufacturer instructions and cannot be modied in any way.
The condensation exhaust system downstream of the appliance (1) must comply with the rele-
vant legislation and standards.
The construction of the condensation exhaust system downstream of the appliance is the re-
sponsibility of the installer. The condensation exhaust system must be dimensioned and installed
in such a way as to guarantee the correct evacuation of the condensation produced by the ap-
pliance and/or collected by the evacuation systems of combustion products. All the components
of the condensation exhaust system must be made in a workmanlike manner using materials that
are suitable for withstanding the mechanical, thermal and chemical stresses of the condensation
produced by the appliance over time. Note: If the condensation exhaust system is exposed to the
risk of frost, always provide an adequate level of insulation of the pipe and consider any increase
in the diameter of the pipe itself.
The condensation exhaust pipe must always have an adequate slope level to prevent the con-
densation from stagnating and its proper drainage.
The condensation exhaust system must have an inspectable disconnection (2) between the con-
densation exhaust pipe of the appliance and the condensation exhaust system.
The disconnection must be such as to ensure an atmospheric connection between the inside
of the condensation exhaust system pipe and the environment in order to avoid that the down-
stream exhaust pipe of the product can take on positive or negative pressure with respect to the

3.9 Positioning the wall-mounted boiler and hydraulic
connections (Fig. 10)
The boiler comes as standard with a boiler support plate. The position and dimension of hydraulic
ttings are shown in the detail drawing.
For the assembly, proceed as follows:
-fasten the boiler support plate (F) to the wall and use a spirit level to make sure it is perfectly
horizontal
-mark the 4 holes (ø 6 mm) envisaged for securing the boiler support plate (F)
-make sure that all measurements are exact, then drill the wall using drill tips with the diame-
ters indicated above
-x the plate with the built-in template (G) to the wall.
-x the safety valve pipe supplied in the documentation envelope onto the coupling of the
safety valve (S), then connect it to an adequate discharge system.

OTBus remote control connection
When an OTBus remote control is connected to the system, the boiler display shows the fol-
lowing screen:
In particular on the boiler display:
it is no longer possible to set the boiler OFF/WINTER/SUMMER status (it is set by the OTBus
remote control)
it is no longer possible to set the domestic hot water setpoint (it is set by the OTBus remote
control)
the combination of the A+B keys remains active for the setting of the DOMESTIC HOT WA-
TER COMFORT function
the domestic hot water setpoint is displayed in the INFO menu
the heating setpoint set on the boiler display is used only if there are heat requests from the
TA and the OTBus remote control does not have a request if the parameter:
P3.11 = 1
or
P3.11 = 0 and the jumper on 1-2pin of X 21 is closed.
to activate the COMBUSTION CHECK function with an OTBus remote control connected,
you must temporarily disable the connection by setting the parameter P8.03 = 0. Remember
to reset this parameter once the function has nished.
We can see that it is not possible, with the OTBus remote control connected, to change the
values of the parameter P4.12 and P4.23 from 0 to 1.
Note: an OTBus remote control cannot be connected if the system already has BE16 in-
terface boards. For the same reason it is not possible to connect BE16 boards if there is
already an OTBus device.
In this case the system gives the following error message: <<OTER>>.
High voltage connections
The connection to the mains supply must be made via a separation device with an omnipolar
opening of at least 3.5 mm (EN 60335/1 - category 3). The appliance works with alternating cur-
rent at 230 Volt/50 Hz, and is in compliance with Standard EN 60335-1. It is obligatory to make
the connection with a safe ground/earth, in compliance with current directives.
b
The installer is responsible for ensuring the appliance is suitably earthed; the manu-
facturer will not be liable for any damage resulting from an incorrect or absent earth
connection
b
It is also advisable to respect the phase-neutral connection (L-N).
b
The earth conductor must be a couple of cm longer than the others.
b
To create the seal of the boiler use a clamp and tighten it on the cable grommet used.
The boiler can operate with a phase-neutral or phase-phase (not oating) power supply.
It is forbidden to use gas and/or water pipes to earth electrical appliances.
Use the power cable supplied to connect the boiler to the mains power supply. If the power cable
has to be replaced, use a HAR H05V2V2-F, 3 x 0.75mm² cable, Ø max external 7 mm.
3.11 Gas connection
The connection of the gas supply must be carried out in compliance with current installation
standards. Before carrying out the connection, check that the type of gas is that for which the
appliance is set up.
3.12 Variable speed circulator
The modulating circulator function is active only in the heating function. In the switching of the
three-way on the domestic hot water, the circulator always operates at maximum speed. The
modulating circulator function applies only to the boiler circulator and not to circulators of any
external devices that are connected (e.g. relaunch circulator).
There are 4 management modes to choose from depending on the situations and the type of
system. Entering the P4 menu, parameter P4.05, it is possible to choose from:
1 VARIABLE SPEED CIRCULATOR WITH PROPORTIONAL MODE (41 <= P4.05 <= 100)
2 VARIABLE SPEED CIRCULATOR WITH CONSTANT ∆T MODE (2 <= P4.05 <= 40)
3 CIRCULATOR IN FIXED MAXIMUM SPEED MODE (P4.05 = 1)
4 EXCEPTIONAL USE OF A STANDARD CIRCULATOR WHOSE SPEED CANNOT BE RE-
GULATED (P4.05= 0)
1 VARIABLE SPEED CIRCULATOR WITH PROPORTIONAL MODE (41 <= P4.05 <= 100)
In this mode the boiler board determines which ow curve to be adopted for the instantaneous
output of the boiler .
2 VARIABLE SPEED CIRCULATOR WITH CONSTANT ∆T MODE (2 <= P4.05 <= 40)
In this mode the installer sets the ∆T value to be kept between delivery and return (e.g.: entering
a value= 10 la the speed of the circulator will change to have a system ow rate with the aim of
keeping the ∆T upstream and downstream heat exchanger of 10°C).
3 VARIABLE SPEED CIRCULATOR WITH FIXED MAXIMUM SPEED MODE (P4.05 = 1)
In this mode the circulator, when activated, always operates at maximum speed.
Used in high pressure drop systems where it is necessary to fully exploit the boiler discharge
head in order to provide sufcient circulation (system ow at maximum speed lower than 600
litres/hour).

7
ENGLISH
Used when there are bottles of mixture with high ow rate in the downstream circuit.
Operationally:
Enter parameter P4.05
Set the value = 1
4 EXCEPTIONAL USE OF A STANDARD CIRCULATOR WHOSE SPEED CANNOT BE RE-
GULATED (P4.05 = 0)
This mode should be used in exceptional cases where you want use a traditional UPS circulator
in the boiler.

3.13 Manual reset of the circulator
The circulator has an electronic reset function, however if a manual reset is necessary, proceed
as follows:
-use a Phillips screwdriver, preferably Phillips no. 2
-insert the screwdriver in the hole until it comes into contact with the reset screw, then press
(basically the screw should go in by about 2 mm) and turn anti-clockwise.
3.14 Removing the casing
To access the components inside, remove the casing as indicated below:
-nd and unscrew the 2 screws (A - g. 11) xing the casing to the boiler levering the two xing
clips (C - g. 11), detach the bottom part of the casing
-lift the casing upwards to release it from the top tabs (B - g. 11), then remove it.
WARNING
b
If removing the side panels, put them back in their initial position, referring to the adhe-
sive labels on their walls.
b
If the front panel is damaged it must be replaced.
b
The noise absorbing panels inside the front and side walls ensure the airtight seal for the
air supply duct in the installation environment.
b
It is therefore CRUCIAL after the dismantling operations to correctly reposition the com-
ponents to ensure the boiler's seal is effective.
3.15 Flue gas exhaust and combustion air suction (Fig. 12)
To evacuate the combustion products, refer to UNI 7129-7131. Always comply with local stan-
dards of the Fire Department, the Gas Company and with possible municipal dispositions.
The evacuation of the combustion products is carried out by a centrifugal fan and the control
board constantly monitors that it is operating correctly.
It is essential for the evacuation of the ue gases and the adduction of the boiler's combustion air
that only original pipes be used (except C6) and that the connection is made correctly as shown
in the instructions provided with the ue gases accessories.
A single ue can be connected to several appliances provided that every appliance is the con-
densing type.
The boiler is a C-type appliance (with airtight chamber), and must therefore have a safe connec-
tion to the ue gas discharge pipe and to the combustion air suction pipe; these both carry their
contents outside, and are essential for the operation of the appliance.
Both concentric and twin terminals are available.

use the accessories for condensing appliances that best t the installation characteristics
(see catalogue).
b
The maximum lengths of the pipes refer to the ue accessories available in the cata-
logue.
b
It is compulsory to use specic pipes.
b
The non insulated ue gas outlet pipes are potential sources of danger.
b
The use of a longer pipe causes a loss of output of the boiler.
b
Make sure the ue gas discharge pipe is tilted 3° towards the boiler.
b
The exhaust pipes can face in the direction most suited to the installation requirements.
b
As envisaged by current legislation, the boiler is designed to take in and dispose of ue
gas condensate and/or meteoric water condensate deriving from the ue gas discharge
system using its own siphon.
b
if a condensate relaunch pump is installed, check the technical data (provided by the
manufacturer) regarding output, to ensure it operates correctly.

3.16 Installation on collective ues in positive pressure (g 18)
The collective ue is a ue gas exhaust system suitable for collecting and expelling the combu-
stion products of several appliances installed on several oors of a building.
The positive pressure collective ues can only be used for type C condensing appliances. The-
refore the B53P/B23P conguration is forbidden. The installation of boilers under collective pres-
sure ues is allowed exclusively in G20.
The boiler is sized to operate correctly up to a maximum internal pressure of the ue no higher
than the value of 25 Pa. Check that the fan speed corresponds to what is shown in the table
"technical data".
Make sure that the air intake and exhaust pipes of the combustion products are watertight.
WARNINGS:
b
The appliances connected to a collective pipe must all be of the same type and have
equivalent combustion characteristics.
b
The number of devices connected to a positive pressure collective pipe is dened by
the ue designer.
The boiler is designed to be connected to a collective ue sized to operate in conditions where
the static pressure of the collective ue pipe can exceed the static pressure of the collective air
duct of 25 Pa in the condition in which n-1 boilers work at maximum rated heat input and 1 boiler
at the minimum rated heat input allowed by the controls.
b
The minimum permissible pressure difference between the ue gas outlet and the com-
bustion air inlet is -200 Pa (including - 100 Pa of wind pressure).
For both types of exhaust, further accessories are available (curves, extensions, terminals, etc.)
which make possible the ue gas exhaust congurations foreseen in the boiler booklet.
b
The pipes must be installed in such a way as to avoid condensation sticking which would
prevent the correct evacuation of the combustion products.
b
A data plate must be present at the connection point with the collective ue pipe. The
plate must include at least the following information:
-the collective ue is sized for boilers C(10) type
-the maximum permissible mass ow of the combustion products in kg/h
-the dimensions of the connection to the common pipes
-a warning concerning the openings for the air outlet and the entry of the combustion
products of the collective pressure pipe; these openings must be closed and their
tightness must be checked when the boiler is disconnected
-the name of the manufacturer of the collective smoke pipe or its identication symbol.
b
See applicable legislation for the discharge of the combustion products as well as local
regulations.
b
The ue gas pipe must be suitably selected based on the parameters shown below.

3.18 Draining the heating system
Before draining, set the boiler to OFF and shut off the electrical supply setting the system's main
switch to “off”.
-Close the heating system's taps (if present).
-Connect a pipe to the system discharge valve (C - g. 19), then manually loosen it to let the
water ow out.
-Once the operations have been completed, remove the pipe from the system discharge valve
(C - g. 19) and close it again.
3.19 Emptying the domestic hot water circuit
Whenever there is risk of frost, the domestic hot water system must be emptied in the following
way:
-turn off the main water supply tap
-turn on all the hot and cold water taps
-drain the lowest points.
3.20 Condensate siphon
When the boiler is rst started the siphon for collecting the condensate is empty.
When eliminating air from the boiler, the siphon lls.
-Slowly open the de-aeration tap (A - g. 19)and leave it open until the amount of water con-
tained in the siphon reaches the ledge.
-Close the de-aeration tap (A- g. 19)
-Check that there are no leaks from the SRD device connection zone and that the device
allows the liquid to run off correctly.
-Check that the system pressure has not dropped below 1 bar. If necessary, ll the system.
Repeat this operation during maintenance work.
CHECK THAT THE CONDENSATE DRAIN OUTLET SIPHON CONTAINS WATER, IF IT WAS
NOT FILLED PROCEED AS DESCRIBED ABOVE.
b
The terminal of the collective pipe must generate an upward air current.
b
Before attempting any operation, disconnect the appliance from the electrical supply.
b
Before assembling, lubricate the gaskets with a non-corrosive glide lubricant.
b
The ue gases discharge pipe should be inclined, if the pipe is horizontal, by 3° towards
the boiler.
b
The number and characteristics of the exhaust ventilation devices which are the real
characteristics of the ue itself.
b
The condensation can ow inside the boiler.
b
The maximum recirculated value allowed in wind conditions is 10%.
b
The maximum permissible pressure difference (25 Pa) between the combustion pro-
ducts inlet and the air outlet of a collective ue can not be exceeded when-1 boiler work
at the maximum nominal heat output and 1 boiler within minimum temperature allowed
by the checks.
b
The collective smoke pipe must be adequate for an overpressure of at least 200 Pa.
b
The collective ue must not be equipped with a wind-proong device.
At this point it is possible to install the curves and extensions, available as accessories, depen-
ding on the type of installation desired.
The maximum permissible lengths of the ue pipe and the air intake pipe are given in the instruc-
tion manual of the reference device (g 18a-18b).

Note: the rst lling operation must be carried out by turning the lling tap (B - g. 19)with the
boiler OFF.
Note: each time the boiler is powered up, the automatic venting cycle is carried out.
Note: the presence of a water alarm (40, 41 or 42) does not allow the venting cycle to be carried
out. The presence of a domestic hot water request during the venting cycle interrupts the venting
cycle.
Once the hydraulic connections have been made, ll the heating system as follows:
-Set the boiler to OFF by pressing button 1
-Open the plug of the air vent valve (D - g. 19) by two or three turns to allow the continuous
bleeding of the air, and leave the valve cap (D - g. 19) open
-Connect the supplied silicone pipe to the de-aeration tap (A - g. 19) and take a bucket to
collect any water that may come out after bleeding
-Open the de-aeration tap (A - g. 19)
-Turn on the lling tap (B - g. 19)
-Wait until the water comes out continuously from the de-aeration tap (A - g. 19), then close it
-Wait for the pressure to increase: check that it reaches 1-1.5 bar; then close the system lling
tap (B - g. 19).
Note: if the mains pressure is less than 1 bar, keep the system lling tap (B - g. 19)open during
the venting cycle and close it once it has nished.
-To start the vent cycle shut off the electrical power for a few seconds; connect the power again
leaving the boiler OFF. Check that the gas tap is closed.
-At the end of the cycle, if the circuit pressure has dropped, open the lling tap (B - g. 19)
again to bring the pressure back up to recommended levels (1-1.5 bar)
The boiler is ready after the vent cycle.
-Remove any air in the domestic system (radiators, zone manifolds, etc.) using the bleed
valves.
-Once again check that the system pressure is correct (ideally 1-1.5bar) and restore the levels
if necessary.
-If air is noticed when operating, repeat the vent cycle.
-Once the operations are nished, open the gas tap and ignite the boiler.
At this point it is possible to carry out any heat request.

P8 (CONNECTIVITY menu)
P8.01
This parameter is used to manage the boiler remotely. Three values are available for this
parameter:
0 = FACTORY-SET VALUE. The interface on the machine is operational but the boiler can
also be controlled remotely if the Modbus device for WiFi/Bluetooth connection is atta-
ched to the connector under the shelf (optional accessory, not supplied as standard)
1 = remote boiler control is disabled, only the interface on the machine is operative. If con-
nected, the Modbus device for WiFi/Bluetooth connection is ignored, while a connection
error is generated when connecting a Modbus remote control (REC10) and the error
<<COM>> is shown
2 = you can connect a Modbus remote control (REC10) to control the boiler; the interface on
the machine is disabled and <<RCTR>> is shown on the display. Only the MENU button
for changing parameter P8.01 remains active.
P8.03
This parameter is used to enable remote boiler management using an OpenTerm device:
0 = With the OT+ function disabled, you cannot control the boiler remotely using an OT+
device. If this parameter is set to 0, any OT+ connection is instantly interrupted, and the
“xx” icon and “OTB” message on the display are switched off
1 = FACTORY-SET VALUE. With the OT+ function enabled, you can connect an OT+ device
to control the boiler remotely. When you connect an OT+ device to the boiler, the “xx” icon
lights up on the display and “OTB” appears.
4.4 Setting the thermoregulation
Enabling THERMOREGULATION occurs in the following way:
access the technical parameters menu, as indicated in the paragraph "3.23 Access to the
parameters" .
select the menu P4 and then P4.18=1.
Thermoregulation only works with the outdoor temperature sensor connected and active only for
the HEATING function.
If P4.18 = 0 or outdoor temperature probe disconnected the boiler operates at a xed point.
The temperature measured by the outdoor temperature sensor is displayed in "4.20 INFO menu"
under I0.09.
The thermoregulation algorithm will not directly use the outdoor temperature, but rather a calcu-
lated outdoor temperature that takes into account the building's insulation: in buildings that are
well insulated, the outdoor temperature variations will have less impact than those that are poorly
insulated by comparison.
REQUEST FROM OT CHRONOTHERMOSTAT
In this case the delivery setpoint is calculated by the chronothermostat according to the outdoor
temperature value and the difference between the ambient temperature and the desired ambient
temperature.
REQUEST FROM ROOM THERMOSTAT
In this case the delivery setpoint is calculated by the adjustment board according to the outdoor
temperature value so as to obtain an estimated outdoor temperature of 20° (reference ambient
temperature). There are 2 parameters that compete to calculate the output setpoint:
slope of the compensation curve (KT)
offset on the reference ambient temperature.
Selecting the thermoregulation curve (parameter P4.19 - g. 20)
The thermoregulation curve for heating maintains a theoretical temperature of 20°C indoors,
when the outdoor temperature is between +20°C and -20°C. The choice of the curve depends
on the minimum outdoor temperature envisaged (and therefore on the geographical location),
and on the delivery temperature envisaged (and therefore on the type of system). It is carefully
calculated by the installer on the basis of the following formula:
KT = T. outlet envisaged - Tshift
20- min. design external T
Tshift = 30°C standard system
25°C oor installations
If the calculation produces an intermediate value between two curves, you are advised to choose
the thermoregulation curve nearest the value obtained.
Example : if the value obtained from the calculation is 1.3, this is between curve 1 and curve 1.5.
Choose the nearest curve, i.e. 1.5.
The settable KT values are as follows:
standard system: 1.0-3.0
oor system 0.2-0.8.
Through the interface it is possible to access the menu P4 and the parameter P4.19 to set the
pre-selected thermoregulation curve:
access the technical parameters menu, as indicated in the paragraph "3.23 Access to the
parameters" .
select the menu P4 and then P4.19
press the key to conrm
set the desired climatic curve with the and arrow keys
conrm with
Enter
.
Offset on the reference ambient temperature (g. 20)
The user can, in any event, indirectly intervene on the value of the HEATING setpoint setting,
with reference to the reference temperature (20°C), an offset within the range -5 - +5 (offset 0
= 20°C).
For correcting the offset see the paragraph "4.8 Adjusting the heating water temperature with an
outdoor temperature sensor connected" .
NIGHT COMPENSATION (parameter P4.20 - g. 20)
If a ROOM THERMOSTAT is connected to a programming timer, from the menu P4 parameter
P4.20 the night compensation can be enabled.
To set the night compensation:
access the technical parameters menu, as indicated in the paragraph "3.23 Access to the
parameters" .
select the menu P4 and then P4.20
press the key to conrm
set the parameter to 1
conrm with
Enter
.
In this case, when the CONTACT is CLOSED, the heat request is made by the ow sensor, on the
basis of the outdoor temperature, to obtain a nominal ambient temperature on DAY level (20°C).
The opening of the contact does not produce a switch-off, but a reduction (parallel translation) of
the climatic curve on NIGHT level (16°C).
Also in this case, the user can indirectly modify the value of the HEATING setpoint inserting once
again an offset on the reference DAY temperature (20°C) rather than NIGHT (16°C) that can vary
within the range [-5 - +5].
For correcting the offset see the paragraph "4.8 Adjusting the heating water temperature with an
outdoor temperature sensor connected" .

4.13 Special domestic hot water functions
The boiler has special functions more a more efcient management of the domestic hot water
when there a high domestic hot water temperature input.
By programming the P5.11 parameter it is possible to activate one or all the following functions,
for more information about setting the parameter see the relative paragraph "4.3 Boiler congu-
ration" .
-Domestic domestic hot water delay function: this function introduces a programmed de-
lay in the starting of the boiler in domestic hot water mode. The delay time is given by the
parameter P5.10.
-Absolute thermostats domestic hot water function: normally the boiler in domestic hot
water mode switches on and off based on thermostats related to the value of the domestic hot
water setpoint (off at setpoint + 5°C and switching back on at setpoint + 4°C). Activating this
function the boiler will switch on ad off based on thermostats independent of the domestic hot
water setpoint (off at setpoint + 65°C and switching back on at 63°C).
4.14 Screed heating function
For a low temperature system the boiler has a "screed heating" function that can be activated
in the following way:
set the boiler to OFF by pressing button 1
access the technical parameters menu, as indicated in the paragraph "3.23 Access to the
parameters" .
select the P4 menu and then P4.09 with the keys ,, conrming the selection with .
(Note: SCREED HEATING is not available if the boiler is a status other than OFF).
To activate the function set the parameter to 1, to deactivate it set the parameter to 0.
The “screed heating” function lasts 168 hours (7 days) during which, in the zones congured as
low temperature, a heating request is simulated with an initial zone outlet of 20°C, then increased
in line with the table on the side.
Accessing the INFO menu from the main page of the interface it is possible to display the I0.01
value regarding the number of hours that have passed since the activation of the function.
Once activated, the function takes priority, if the machine is shut down by disconnecting the
power supply, when it is restarted the function picks up from where it was interrupted.
The function can be interrupted before it has nished by setting the boiler to a status other than
OFF or by selecting P4.09 = 0 from the menu P4.
Note: The temperature and increase values can be set to different values only by qualied per-
sonnel, only if strictly necessary. The manufacturer declines all responsibility if the parameters
are incorrectly set.

b
The combustion analysis function is normally carried out with the three-way valve posi-
tioned on heating. It is possible to switch the valve to domestic hot water generating a
domestic hot water heat request at maximum output while the function itself is being car-
ried out. In this case the temperature of the domestic hot water is limited to a maximum
of 65°C. Wait for the burner to re.
The boiler will operate at maximum heating output and it will be possible to regulate the com-
bustion.
Remove the screw and the cover on the air distribution box ( A-B ).
Insert the analysis probe adapter ( D ) located in the documentation envelope, into the hole
for the combustion analysis.
Insert the ue gases analysis probe into the adaptor.
Control the combustion, checking that the CO2 values match those in the table.
When the control is completed, remove the analyser probe and close the combustion
analysis sockets with the relative plugs and screw.
Put back and keep the analysis probe adapter supplied with the boiler in the documentation
envelope.
