6.2.1 - Thermoregulation - Setting the gradient
PressingkeyKM down for10seconds andthenkeyK2 (IMP),the CURVAESTparameterisimmediatelydisplayed.
Using the keys K+ o K- , it is possible to change the setting.
The graph in figure 4, shows the ratio between the external temperature and the supply temperature calculated in
relation to the value assigned to the CURVAEST parameter.
The installer can use this graph in order to establish the exact CURVAEST to be set in relation to the geographic
area where the installation will take place (typically, the curves chosen for Italian regions range between 0.6 and
1.1 for radiant panel systems).
Theadjustment of the supply temperaturein relation tothe externaltemperature is activeonly if the MODOFUNZ
parameter is set at 3 (see section 6.2.3)
Figure 4 - Ratio between supply temperature and external temperature
Normally,the adjustmentof justthe CURVAEST (gradient) as per thegraph infigure 4, isnot enoughto adjust the
supply temperature exactly, in relation to the external temperature. For this purpose, it is possible to adjust the
parallelism of this line as well, taking action directly on the remote time control, requesting a room temperature
other than 20°C. Figure 5 shows how the line (in this case with a CURVA EST gradient = 2.0) can move on a
parallel in relation to the temperature set on the remote control.
To set the temperature on the remote control, see section 5.2, or 5.8.
This type of setting is advisable above all else for radiant panel systems, where the remote control cannot be
positioned as a sensor of a characteristic room temperature, or in situations where there are thermostats which
regulate the temperature zone by zone.

6.2.2 - Thermoregulation - Correction with room temperature
Pressing key KM down for 10 seconds, then key K2 (IMP) and finally key K4 (>>) the COMPENSAMB parameter
is displayed immediately. Using keys K+ o K-, it is possible to change the setting.
When the value of the COMPENS AMB parameter differs from 0, the compensation of the room temperature is
active.
The effect of the room temperature compensation is the automatic parallel shift of the curve as per figure 4.
Inthis way,the parallel translationof the line, which in the previous section wascarried out manually, is now made
automatically on the basis of the temperature registered by the remote control in the room.
The shifting of the curve, defined as Delta, is calculated on the basis of the error between the value of the room
temperature requested and that actually read by the remote control.
The Delta is also influenced by the parameter defined as room compensation (COMPENS AMB) which can be
selected from between 0 and 20 (as can be seen from the graph in figure 6).
The rules for the correct setting of the room compensation value (COMPENS AMB) are:
· the compensation of the room temperature makes it possible to put the heating system in steady state much
faster and automatically compensate the imperfect selection of the CURVA EST;
· the higher its value, the quicker the putting of the heating system in steady state is;
· too high a value may cause the system to react too quickly, involving the consequent sudden igniting and
switching off of the boiler;
· generally, a large heating system, which requires a long period before it reaches steady state, requires a higher
room compensation value with respect to a smaller heating system which requires a shorter period before it
reaches steady state;
· the room compensation works correctly only if the CURVA EST has been correctly chosen.
The room compensation is active only if the MODO FUNZ parameter is set at value 3 (see section 6.2.3)
This type of adjustment is advised for all radiant panel type systems where the remote time control can be
installed in an area where the temperature is characteristic of the entire area to be heated.

6.2.3 - Thermoregulation - Choosing the operating modes
The MODO FUNZ parameter is one of the most important to be adjusted. On the basis of the setting of this
parameter, the type of thermoregulation to be used in the system is chosen. Therefore, it is indispensable to
choose the type of thermoregulation carefully, in relation to the type of system owned, in order to achieve the best
degree of comfort envisaged.
Pressing key KM down for more than 10 seconds, then key K2 (IMP), and subsequently key K4 (>>) until MODO
FUNZ is displayed, it is possible to select, using keys K+ e K-, one of the 4 types of thermoregulation available:
1 · room thermoregulation with set supply temperature
2 · room thermoregulation in relation to the room temperature
3 · room thermoregulation in relation to the external temperature, with or without room temperature
4 · thermoregulation with exclusion of the room temperature and two-point adjustment
Room thermoregulation with set supply temperature (MODO FUNZ = 1)
The user sets the room temperature desired and the remote control generates a heat request to the boiler (pump
comes on), every time the room temperature falls below the temperature requested. Vice versa, every time the
roomtemperature rises above that set, the remote control interruptsthe heat request tothe boiler (pump switches
off). In this operating mode, the supply temperature to the radiators is set at the value set on the REG RISCALD
parameter (see section 6.2).
This type of thermoregulation is recommended for a system with radiators or convector fans
Room thermoregulation in relation to the room temperature (MODO FUNZ = 2)
The heating supply temperature is calculated using a PID type algorithm so that the room temperature, read by
the remote control, corresponds with that set by the user; the value calculated corresponds to the value of the
heatingsupply temperature (TEMPCALC parameter, seesection 6.1).Thisvalue however isalways limitedto the
value set on the REG RISCALD parameter (see section 6.2.8).
This type of thermoregulation is recommended for systems with radiators, convector fans or radiant panels where
the temperature of the room where the remote time control is located is characteristic of all the rooms heated.
Room thermoregulation in relation to the external temperature, with or without
room temperature (MODO FUNZ = 3)
The heating supply temperature is calculated using a formula which takes into account the CURVAEST selected
(seesection 6.2.1); thevalue calculated (TEMPCALC parameter,see section 6.1)corresponds with thesetting of
theheating supplytemperature. Thisvalue however isalways limitedto thevalue of theREG RISCALDparameter
set (see section 6.2.8).
In this operating mode, if the COMPENS AMB parameter (see section 6.2.2) is set at zero, the adjustment of the
supply temperature is made without considering the room temperature read by the remote control. Therefore, the
installer will have to find the right angle of the line, adjusting the CURVAEST parameter as per section 6.2.1 and
the right parallelism, adjusting the room temperature as per sections 5.2 and 5.8.
This type of thermoregulation is recommended for a system with radiant panels where the rooms heated are
served by room thermostats which act on the area valves, or in systems where it is not possible to install the
remote control in a place where the room temperature registered is characteristic of the building. In such cases,
the supply temperature is adjusted exclusively in relation to the external temperature according to the ratio shown
in the graphs as per figures 4 and 5.
If the COMPENS AMB parameter (see section 6.2.2) is set at a value other than zero, the room temperature
registered by the remote time control intervenes to correct the supply temperature on the basis of the matters
already illustrated in section 6.2.2 and figures 6 and 7.
This type of thermoregulation is recommended for a system with radiant panels where the temperature of the
room in which the remote time control is located is characteristic of all the rooms heated.
Inall theafore-mentioned cases, whenthe externaltemperature isgreater than thecalculated supplytemperature
(parameter TEMP CALC as per section 6.1), the heating is shutdown.
Thermoregulation with exclusion of the room temperature and two-point

19
adjustment (MODO FUNZ = 4)
Theroom temperatureand theexternal temperaturedo notinteract on the operating modeof thethermoregulation
in question.
Theadjustment of the supply temperatureto the radiatorsis carriedout at twotemperature levels, set respectively
at TMP MIN RIS (minimum supply temperature, see section 6.2.7) and REG RISCALD (maximum supply
temperature, see section 6.2.8).
Themeaningusually attributedto theparametersTMPAMBT0,TMPAMBT1 andTMPAMBT2(room temperature
levels which can be selected for the automatic operating mode of the room thermostat, see section 5.8), changes
as indicated below:
TMP AMB T0 = heating request absent
TMP AMB T1 = heating request present with supply adjustment at value of TMP MIN RIS parameter
TMP AMB T2 = heating request present with supply adjustment at value of REG RISCALD parameter
By means of the programming of the heating timer (see section 5.8), the user establishes when, over a period of
24 hours, to set the boiler going in heating mode (levels T1 or T2) or not (level T0) and what the setting of the
supply temperature must be (TMP MIN RIS or REG RISCALD) for the water of the heating system.
When this thermoregulation operating mode is selected:
- the PRE RISCALD function (see chapter 6.2.6) is automatically disabled;
- the programming of the TMP AMB T0, TMP AMB T1 and TMP AMB T2 parameters as per section 5.9, is
automaticallydisabled;
- during the manual adjustment of the room temperature, as per section 5.2, it permits the adjustment of the
desiredroom temperature, at three levelscorresponding to 0 = TMBAMB T0, 1 = TMPAMB T1 and 2 =TMP AMB
T2.
6.2.4 - Hour type displayed
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TIPO
ORAis displayed, it is possible to select, using keys K+ e K-, the 12 hours or 24 hours timing display. Setting the
parameter at 1, one obtains the 24 hour display, whilst setting it at 2 the 12 hour display is shown.
6.2.5 - Domestic hot water programme type
Pressing theKM keydown for morethan 10seconds and thenkey K2(IMP) followed bykey K4(>>) until PROGR
SAN is displayed, it is possible to select, using keys K+ e K-, the operating of the domestic hot water function, in
the following manner:
1 = domestic hot water service always active;
2 = possibility of carrying out the time programming of the domestic hot water service independently from the
heatingservice(the function,whenactive,is shownonthe displayusingthe clocksymbol).Forthe programming
of the domestic hot water service, refer to section 5.8;
3 = the domestic hot water service follows the time programming made for the heating service exactly.
Due to how the boiler is conceived, it is advisable to keep the parameter at 1 or 3.
6.2.6 - Automatic pre-heating
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until PRE
RISCALDis displayed,it is possibleto select,using keys K+e K-, the typeof pre-heatingone intendsto carry out.
The parameter can adopt the following values:
1 = pre-heating enabled in adaptive mode;
2 = pre-heating enabled with a ramp of 3°C/hour;
3 = pre-heating disabled.
If this parameter is set at 3, during the time programming of the heating function, the user must bear in mind to
switch on the heating in advance with respect to the effective need, due to the thermal inertia of the plant (high in
the case of radiant panels, low in the case of radiators, uninfluential in the case of convector fans).
So as to avoid having to take these times into consideration, being among other things difficult to calculate and
variablein relationto the seasonand typeof plant,it isadvisable tokeep theparameterat thevalue of1 or2, where
the remote time control carries out an automatic detection of the system’s features (with a frequency of 10
minutes), thus calculating the thermal inertia, or the time necessary for achieving a specific room temperature. In

20
this way, when the time programming is carried out it will be sufficient to introduce the switching on and switching
offof the heatingin correspondencewith thetimeperiod ofeffective need;the remote timecontrol willautomatically
take steps to bring forward the ignitions so as to obtain the desired room temperature, in the time period set.
6.2.7 - Minimum supply temperature
Pressingthe KMkey downfor morethan 10seconds andthen keyK2 (IMP)followed bykey K4(>>) untilTMP MIN
RIS is displayed, it is possible to select, using keys K+ e K-, the minimum supply temperature for the heating. It
is recommended that it be left at 20°C.
Onlyin theevent thatthe MODOFUNZ parameter(see section6.2.3) hasbeen set at 4, theTMP MINRIS mustbe
adjusted to the supply temperature, corresponding to the energy saving timeband TMP AMB T1.
6.2.8 - Maximum supply temperature
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until REG
RISCALD is displayed, it is possible to select, using keys K+ e K-, the maximum supply temperature for the
heating. It is recommended that it be left at 45°C.
In the event that the MODO FUNZ parameter has been set at 1 (see section 6.2.3), the REG RISCALD must be
adjusted to the supply temperature, corresponding to the adjustment temperature.
In the event that the MODO FUNZ parameter has been set at 4 (see section 6.2.3), the REG RISCALD must be
adjusted to the supply temperature, corresponding to the comfort timeband TMPAMB T2.
6.2.9 - Pre-setting of room temperature
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until TMP
AMB T0/T1/T2 is displayed, it is possible to select, using keys K+ e K-, the room temperature values, envisaged
during the time programming of the heating function (see section 5.8). The operation for adjusting TMP AMB T0,
TMP AMB T1 and TMP AMB T2, corresponds with the same regulation as per section 5.9.
Ifthe MODO FUNZ parameter hasbeen set at 4 (seesection 6.2.3) theadjustment ofTMP AMB T0,TMP AMBT1
and TMPAMB T2 is disabled.
6.2.10 - Pre-setting of domestic hot water temperature
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until REG
SAN is displayed, it is possible to select, using keys K+ e K-, the exit temperature of the domestic hot water
between40 and 65°C. Thefunction corresponds with the adjustment of the domestic hot water as per section 5.3.
6.2.11 - Pre-setting of system supply type
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until
RIEMPIMENTO is displayed, it is possible to select, using keys K+ e K-, the following values:
1 = manual
2 = automatic
3 = disabled
If the boiler comes with an automatic valve, for filling the heating circuit, with the RIEMPIMENTO parameter set at
2,the remote timecontrol takes stepsto carry out the fillingof the boilereach time thewater pressure dropsbelow
a pre-established value.
In the event that the parameter is set at 1or 3, the filling of the system must always take place manually (follow the
boiler instruction manual, so as to carry out the filling of the heating circuit’s system).
6.2.12 - Correcting the room temperature read
Pressing the KM key down for more than 10 seconds and then key K2 (IMP) followed by key K4 (>>) until CORR
TAMB is displayed, it is possible to select, using keys K+ e K-, the correction of the reading of the room sensor,
with respect to the actual temperature. If the room temperature read by the remote time control is influenced by
the installation position (e.g. installation on a wall which faces outside, installation on a thermal brigde, etc.) it is
possible to correct the temperature of a value by more or less two degrees, using the CORR TAMB parameter.
