Electrostatic discharge can cause damages of electronic components
The controller is equipped with six relays in total, to which
loads (actuators) such as pumps, valves, mixers and auxiliary
relays can be connected:
• Relays R1 ... R3 are semiconductor relays, designed for
pump speed control.
R1 ... R3 = normally open R1 ... R3
N = neutral conductor N (terminal block)
PE = protective earth conductor PE
(terminal block)
• Relays R4 and R5 are electromechanical relays with
one shutter:
R4, R5 = normally open R4, R5
N = neutral conductor N (terminal block )
PE = protective earth conductor PE
(terminal block)
• Relay RP is a potential-free relay with change-over-
contact:
RP-M = centre contact RP
RP-A = normally open RP
RP-R = break contact RP
RP switches parallel to R3 in all systems with afterheating
(SYS 3, 10, 12, 15, 19, 22, 25, 28) to provide a boiler demand
if necessary.
1.2.3 Data communication / Bus
Note
The relays R1 up to R3 are semiconductor relays for pump speed control. A minimum load of
20 W (power consumption of the consumer) is
required for faultless function. The 4.7nF capacitor from the accessory bag must be connected
in parallel to the respective relay output if it
feeds auxiliary relays, motor valves, etc.
The minimum pump speed must be set to 100%
when auxiliary relays or valves are connected.
®
The controller comes with a RESOL VBus
for data
transfer with and energy supply to external modules. The
connection is carried out at the terminals marked „VBus“
(either polarity). One or more RESOL VBus® modules can
be connected via this data bus, e.g.:
• RESOL calorimeter WMZ
• RESOL large display GA3, smart display SD3
• RESOL Data logger, DL2
• RESOL Data remote display
®

connection terminals
Additionally, the controller can be connected to a PC with
a RESOL RS-COM adapter. With the RESOL ServiceCenter
Software (RSC) the controller parameters can be changed,
measurements can be read out, processed and visualised. It
allows easy function control and adjustment of the system.
The software can be downloaded for free at www.resol.com
The controller is equipped with 10 sensor inputs in total.
The protective earth connection for sensors is effected by
the protective earth terminal block (GND).
• The temperature sensors are connected to the termi-
nals S1 ... S8 and GND with either polarity.
• A flowmeter RESOL V40 can be connected to the ter-
minals V40 and GND with either polarity.
• The irradiation sensor (CS10) is to be connected
to the terminals CS10 and GND with correct polarity.
Connect the terminal GND of the sensor to the terminal
GND of the controller, and the terminal CS of the sensor
to the terminal CS10 of the controller.
conductor L
The power supply to the controller must be carried out via
an external power switch (last step!) and the supply voltage
must be 220 ... 240 V~ (50 ... 60 Hz). Flexible cables must
be attached to the housing with the enclosed strain relief
and the corresponding screws or be run into the controller
housing in a cable conduit or trunking.
The controller is operated via the 3 push buttons below the
display. The forward-button (1) is used for scrolling forward
through the display menu or to increase the adjustment values.
The backward-button (2) is similarly used for scrolling backwards and reducing values.

4.3.3 Maximum store temperature
First the controller works as a standard differential
controller. If the switch-on difference (DT O / DT1O / DT2O) is reached, the pump is activated at full speed for
10 seconds. The speed is then reduced to the minimum
pump speed value (nMN / nMN1 / nMN2 = 30 %). If the
temperature difference reaches the adjusted set value (DT S / DT1S / DT2S / DT3S), the pump speed increases
by one step (10%). If the difference increases by 2 K (RIS / RIS1 / RIS2 / RIS3), the pump speed increases by 10 %
respectively until the maximum pump speed of 100 % is
reached. The response of the controller can be adapted
via the parameter „Rise“. If the temperature difference
falls below the adjusted switch-off temperature difference
(DT F / DT1F / DT2F), the controller switches off.
DT O and DT S are locked against each other. DT S
must be at least 0,5 K higher than DT O.

Once the adjusted maximum temperature is exceeded,
the solar pump is switched off and further loading of the
store is prevented to reduce scald risk or system damage.

The controller is equipped with an independent temperature differential regulation for which minimum and
maximum temperature limitations as well as corresponding switch-on and -off temperatures can be separately
adjusted. Only possible for Arr = 2, 8, 11, 13, 16, 17, 18, 20,
24, 26 and 30 (e.g. for solid fuel boilers or heat exchange
regulation.)
If MX3O is exceeded, relay 2 is switched off until the
sensor falls below MX3F.
Reference sensor for this function:
S3 at Arr 8, 13, 20, 26 (TSTU)
S4 at Arr 2, 11, 16, 17, 18, 24, 30 (TST2, TFSB)
If the sensor temperature falls below MN3O, relay 3
is switched off until the temperature exceeds MN3F..

Note
The controller is also equipped with a nonadjustable emergency switch-off if the store
reaches 95 °C. The reference sensor is S2 (or
S3 for two store systems).

factory setting: 120 °C
If the adjusted collector limit temperature (EM / EM1 /
EM2) is exceeded the solar pump (R1 / R2) is deactivated
in order to avoid a damaging overheating of the solar components (collector emergency shutdown). The limit temperature is set to 140 °C by but it can be changed within the
adjustment range of 110 ... 200 °C. The symbol
on the display (flashing).
When the adjusted maximum store temperature is reached,
the system stagnates. If the collector temperature increases
to the adjusted maximum collector temperature (CMX / CMX1 / CMX2), the solar pump is activated until the
collector temperature falls below the maximum collector
temperature. The store temperature may increase (subordinate active maximum store temperature), but only up
to 95 °C (emergency shutdown of the store). If the store
temperature is higher than the maximum store temperature
(S MX / S1MX / S2MX) and if the collector temperature
is at least 5 K below the store temperature, the solar system
remains activated until the store is cooled down below the
adjusted maximum temperature (S MX / S1MX / S2MX)
via the collector and the pipework.
If the system cooling function is enabled,
shown on the display. Due to the cooling function, the system will have a longer operation time on hot summer days
and guarantees thermal relief of the collector field and the
heat transfer fluid.

The minimum collector temperature is the minimum
temperature which must be exceeded for the solar pump
(R1 / R2) to switch on. The minimum temperature prevents
the pump from being switched on too often at low collector
temperatures. If the temperature falls below the minimum
temperature,
The antifreeze function activates the loading circuit between
collector and store if the adjusted antifreeze function is
under-run in order to protect the medium from freezing
or coagulating. If the adjusted frost protection temperature
is exceeded by 1 °C, the loading circuit will be deactivated.
(flashing) is shown on the display.
Note
Since this function uses the limited heat quantity
of the store, the antifreeze function should be
used in regions with few days of temperatures
around the freezing point.
Loading break time / store sequence control /
collector rise temperature
The above-mentioned options and parameters are used in
multi-store systems only.
PRIO 0: in 2-store systems with pump logic (e.g. Arr 6 and
17) if possible, parallel loading is effected; in 2-store systems
with valve logic (e.g. Arr 5) loading is effected in numerical
order.
PRIO 1: priority loading of store 1
PRIO 2: priority loading of store 2
This function aims to extract the maximum solar gain in 2
store systems. If the first priority store cannot be loaded,
the second priority is checked. If useful heat can be added,
it will be loaded for the „oscillating loading time“ („t-run“
- factory default 15 min.) After this, the loading process
stops and the controller monitors the increase in collector
temperature during the break time „t-st“. If it increases by
2°C, the break time timer starts again to allow the collector
to gain more heat. If it does not, but useful heat can be
added to the second priority store, the second store will
be loaded again for the „t-run“ time as before.
As soon as the switch-on condition of the priority store is
fulfilled, it will be loaded. If the switch-on condition of the
priority store is not fulfilled, loading of the second store
will be continued. If the priority store reaches its maximum
temperature, oscillating loading will not be carried out.

If the adjusted maximum store temperature (SMAX, S1MX,
S2MX) is reached, the solar pump remains activated in
order to avoid an overheating of the collector. The store
temperature might continue to increase but only up to
95 °C (emergency shutdown of the store). In the evening
the solar system continues running until the store is cooled
down to the adjusted maximum store temperature via
collector and pipes.
This function helps overcome the non-ideal sensor position
with some tube collectors.
This function operates within a given time frame (06:00 22:00 o‘clock). It activates the collector circuit pump for 30
seconds every 30 minutes in order to compensate for the
delayed temperature measurement.
The collector circuit pump is operated at 100 % speed for
10 seconds, then at 30 % speed for another 20 seconds.
If the collector sensor is defective or the collector is blocked,
this function is suppressed or switched-off.
The thermostat function works independently from the
solar operation and can be used for using surplus energy
or for after-heating.
• AH O < AH F
thermostat function is used for after-heating
• AH F> AH O
thermostat function is used for using surplus energy
In order to block the thermostat function for a certain
period, there are three time frames t1 ... t3. If the function
should be active between 6:00 and 9:00, set t1 O to 6:00
and t1 F to 9:00. The thermostat function is factory set to
continuous operation.
If all time frames stop at 00:00 o’clock, the thermostat function is continuously activated (factory setting).
For control- and service work the operating mode of
the controller can be manually adjusted by selecting
the adjustment value MAN1-6, in which the following
adjustments can be made:
• MAN1, MAN2, MAN3, MAN4, MAN5, MAN6
