1.1 Mounting
1. Installation
Attention! Switch-off power
supply before opening the
housing!
The unit must only be located internally. It is not suitable
for installation in hazardous locations and should not be
sited near to any electromagnetic field.The controller must
additionally be equipped with an all-polar gap of at least 3
mm or with a gap according to the valid installaton
regulations, e.g. LS-switches or fuses. Please pay attention to
a seperate laying of the cable lines and installation of ac
power supply.
1. Unscrew the cross-recessed screw of the cover and
remove it from the housing. Unscrew now the cross-
recessed screws from the clamp cover and remove it.
2. Mark the upper fastening point on the underground and
premount the enclosed dowel and screw.
2. Hang up the housing at the upper fastening point and
mark the lower fastening point on the underground (hole
center distance 160 mm, see back of the base),
afterwards fit the lower dowel. Hang up the housing at
the top and fix it with the lower fastening screw.
3. Connect relay- and sensor cables as well as power cable
according to clamp allocation and fix the ccables with
strain-relief.
4. Reinsert clamp cover and cover of the housing and fix
them with cross-recessed screws.
Tip:
A cable conduit (e.g. 60 x
110 mm²) should be directly
mounted below the
controller in order to
faciliate the connection of
the cables and to guarantee
a clear running of the
cables.The cables must be
brought into the terminal
block with removed cable
insulation.
Scope of accessory bag:
2 x screws and dowels
1 x spare fuse T6,3A
11x strain relief and screw
3 x condenser 4,7 nF

terminal strip (GND).
• The temperature sensors are connected to the
terminals S1 ... S12 and GND (regardless of the polarity).
• The irradiation sensor (CS10) is to be connected to
the terminals CS10 and GND (in consideration of the
polarity!).The connection of the irradiation sensor with
the identification A (anode) is connected to ther terminal
CS10 and the connection with the idientification K
(cathode) is connected to the terminal GND.
•Twoflowmeters RESOL V40 can be connected to the
terminals lmp1, lmp2 and GND (regardless of the
polarity).

1.2.3 Actuators
The controller is totally equipped with 9 relays, to which the
consumer (actuators), e. g. pumps, valves, mixer and
auxiliary relays can be connected:
• The relays R1...R4 are semi-conductor relays, also suited
for pump speed control.
R1-A ... R4-A = normally open R1 ... R4
N = neutral conductor (collective
terminal strip)
PE = protective earth conductor (collective
terminal strip)
• The relays R5 ... R8 are electromagnetic relays with
change-over contact.
R5-A ... R8-A = normally open R5 ... R8
R5-R ... R8-R = break contact R5 ... R8
N = neutral conductor (collective
terminal strip)
PE = protective earth conductor (collective
terminal strip)
• The relay R9 ist ein potenzialfreies Relais mit Wechsel-
kontakt:
R9-M = center contactR9
R9-A = normally open R9
R9-R = break contact R9
1.2.4 Bus
The controller is equipped with two bus interfaces for data
transfer:
1.) The RESOL VBus® for data transfer with and energy
supply of external modules.The connection is effected
at the two terminals marked "VBus®" (any polarity).
One or more RESOL VBus®modules can be
connected by this Data-Bus:
• RESOLWMZ-M1, calorimeter module
• RESOL large displays
• RESOL HKM, modular heating circuit expansion
2.) The RS232-interface for direct connection to a PC.
Measured values and parameter of the controller can
be read out, adjusted processed and visualised by
means of the evaluation tool RSC (Resol Service Cen-
ter Software). The software makes possible a
comfortable paramatrisation and function control of the
system.
RS232-Connection
RJ45-jack
V-Bus
screw terminals
Please note:
the relays R1 up to R4 are
designed as semiconductor
relays for pump speed control.A
minimum load of 20 W (power
consumption of the consumer)
is required for faultless function.
The enclosed condenser must
be paralleley connected to the
respective relay output for
connection of auxiliary relays,
motor valves, etc.
Attention:
The minimum pump speed
must be set to 100% for
connecting of auxiliary relays or
valves.

3.2 Irradiation sensor
The RESOL V40 is a measuring instrument with contact
donator for recording the flow of water or water/glycol
mixtures and is used in combination with the calorimeter
integrated into the DD
DD
DeltaSeltaS
eltaSeltaS
eltaSolol
olol
ol M. After flow of a specific
volume, the V40 sends an impulse to the calorimeter.The
used heat amount is measured by these impulses and a
measured temperature difference with the help of pre-
defined parameters (glycol type, concentration, heat cpacity,
etc.).
3.3 Flowmeter
3. Sensors
3.1Temperature sensors
Precision-platin sensors type PT1000 (FKP and FRP) are
used for the controller RESOL DeltaSol M.
Depending on the individual solar system, the RESOL
product range contains 3 different sensor types: sensors
with immersion sleeves, flatscrew sensors and cylindrical
clip-on sensors.The sensor types FK and FR have the same
electrical features and are available in the same models,
they only differ in the connecting cable:
FK: 1,5 m weather- and temperature resistant silicone cable
for temperatures between -50 °C ... +180 °C, mostly used
for collectors.
FR: 2,5 m PVC cable for temperatures between
-5 °C ... +80 °C, mostly used for stores.
Make sure that all electrical works are carried out according
to the relevant local and IEE-regulations.The sensor cables
carry low voltages and they must not run together in a
cable conduit with cables carrying higher voltages than
50Volts.When using longer cables or cable conduits, please
use screened cables.The sensor cables can be lengthened
up to 100 m, but the cross section must be 1,5 mm² (or
0,75 mm² up to a cable length of 50 m); screened cables
should be used preferably.The sensors must not be in direct
contact with water, please always use immersion sleeves.
The remote control RTA11 allows a comfortable adjustment
of the heating curve of the controller from the living
room.The rise of the heating curve causes an increase in
flow temperature, a fall causes a decrease. The remote
control additionnally contains the functions "heating circuit-
off" and "fast heating-up".
Note:
In order to avoid overvoltage damages at collector sensors
(e.g. from local lightning storms), we recommend to install
the overvoltage protection RESOL SP1.
3.4 Remote control
The solar cell is used for recording of the momentary
irradiation intensity. The short-circuit flow rises with the
increase of irradiation intensity. The relation between the
short-circuit flow and the irradiation intensity is directly
proportional.The connecting cord can be expanded up to
100 m.

The outdoor temperature sensor FAP12 is suitable for
mounting on even surfaces and it is needed for
DeltaSol M’s weather controlled heating curcuit. The
sensor has a wether resistant housing.

4. Basics of operation
4.1 Operating devices and display
The controller is only operated by the 3 pushbuttons beside
the display. The forward-button (1) is used for scrolling
forward through the menu or to increase the adjustment
values. The backward-button (2) is accordingly used the
other way round. Button 3 is used for selection of the menu
lines and confirmation.
yPlese select your requested menu by the buttons 1 and 2.
yShortly press button 3, the selected submenu is now
shown on the display. By pressing the "back"-button, the
display returns to the former menu level.
yPress buttons 1, 2 and 3 several times until the choosen
menu line is reached.
yShortly press button 3 in the relevant menu line for
modification of adjustment values - "change value"
appears on the display - adjust the requested value by
pressing the buttons 1 and 2 (for large intervals, please
keep the button pressed).
yShortly press button 3 in order to confirm the
adjustment.
yPlease reply to the following security request "Store?" by
choosing "yes" or "no" (buttons 1 and 2) and confirm
with button 3.
yNote:
If no input is made within 7 seconds in the modification
mode, the controller automatically changes into the
read-out mode. If no button is pressed for 4 minutes in
the read-out menu, the display returns to the measured-
values menu (in case of an existing message,the display
changes into the message menu). If button 3 is pressed
for 2 seconds, the display goes back to the main menu.
The controller is equipped with a red-/green control lamp.
The following control and system status are signalised:

5. Functions and options
The relais 1 to 4 are designed as semicoductors for usual
stadard pumps to adjust the pump speed.
The relative pump speed controll is adjustable in 10%
measures of the current temperature difference between
collector- and store temperature. At which temperature
difference the pump speed is increased can be adjustet by
the parameter ‘Rise’.
In some cases is it necessary to revise the factory setting of
the minimum pump speed (30%).
Pump speed control:
Solar/Expert/SOLAR CONTROL/TypE
1. none pump speed control deactivated
2. RISE Standard-pump speed control (factory setting)
3. PI-Reg. special pump speed control, more information
on inquiry.
Expert/RelaY/Min-SPEED1 (2,3,4)
Bilancing function: The controller possesses an integrated bilancing function
with it maximum temperatures, hours of operation of the
relais and operation time since commissioning the controller
can be asked.
These values can be reset except of the counter ‘Operating
days’.
Solar/balance values
Heat quantity balancing:
WmZ/WMZ1 (2)
The controller possesses 2 integrated heat amount counter
which enables the 2 principles of heat quantity balancing
functions.The information in Wh, kWh and MWh has to be
added together.
Bilancing without flowmeter RESOL V40
The balancing takes place as estimation with the aid of the
difference between flow- and return temperature and the
adjusted flow rate. The needed sensor must be assigned.
Therefor an already used sensor can be applied. Through
this its original function is not influenced. The bilancing is
realised when the selected output Relais is activated.
Bilancing with flowmeter RESOL V40
The bilancing takes place with the assistance of the difference
between the flow and return temperature and the volume
flow, measured by the flowmeter.The needed sensor must
be assigned.Therefor an already used sensor can be applied.
Through this its original function is not influenced.

Depending on the selected system or activated options
there are up to 5 function blocks and they are composed
of thermostat function, timer and difference functions (see
page 9).With these, further components or functions e.g.
solid fuel boiler, heater support and after heating can be
realised.
These function blocks are assigned to different relais
depending on the selected system (see survey of relais
allocation).The needed sensor must be assigned.Therefor
an already used sensor can be applied.Through this its ori-
ginal function is not influenced.
Function blocks’ fuctions are linked together.

If the adjusted maximum temperature Tspmax is exeeded,
the loading of the store is stopped. If the store cools down
by more than 2 K, the store loading starts again.
Maximum store temperature:
Security switch-off of the store: If the cooling option is activated (e.g. collector cooling), the
store is charged beyond the adjusted maximum tempera-
ture.
In order to avoid too high temperature in the store, the se-
curity switch-off of the store is additionally provided, which
also blocks the store for cooling option. If a store tempe-
rature of 95 °C is reached, the security switch-off is activa-
ted.
Tspmax:
Adjustment range 4 ... 95 °C
Factory setting 60 °C
Hysteresis 2 K (Factory setting)
Fixed value 95 °C
Hysteresis = 2 K
Store blocked: A store is blocked if either the belonging sensor is defect
or the security switch-off temperature is reached.
Hydraulics variants:
Solar/Options/loading
The systems can be distiguished into pump- and ventil-dri-
ven systems.The adjustment takes place according the survey
of the system with its hydraulic variants (see page 8).

Cooling function: The cooling function can be used in 1-store systems. If the
store is at maximum limitation, the surplus energy in the
collector can be derived.The pump output (provided that
it is activated) is controlled with relative maximum pump
speed.
Operation mode (switching conditions): If the store is at maximum limitation and the switch-on
temperature difference DeltaTon between collector and
store is reached, the solar circuit (primary) and the cooling
relay are operated.
If the switch-off temperature difference ∆Toff is underrun in
this period, the solar circuit and the cooling relay are
switched-off.
2-collector systems: Only the collector circuit, which complies with the above
described switch-on criteria, is operated in these systems.
Collector security switch-off: In case of high collector temperatures (dependant on e.g.
system pressure or content of frost protection), the heat
transport medium evaporates . That means, that a solar
charge is no longer possible.
If the adjusted temperature threshold Tcolsec is exceeded,
the charge at each collector is suspended.
Note: if the option "collector cooling" is activated, the
security switch-off temperature can not be adjusted lower
than the maximum collector temperature (Tcolmax).
Collector blocked: A collector is considered to be blocked if either the sensor
is defect or the securtiy switch-off temperature is reached.
Solar collector blocked: A collector for solar operation is considered to be blocked
if the adjusted minimum temperature is not exceeded or the
condition "collector blocked" is achieved.
Store charging: If the adjusted switch-on difference ∆Ton between collector
and store is exceeded, the store is charged.
If this difference falls under the adjusted switch-off difference
∆Toff, the store is again charged.
The store charge is also suspended if the relevant store or
collector is blocked (collector solar blocked) or if the store
is at maximum limitation.
