1.2.2 Actuators
(pumps, valves, etc.)
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
VBus®
connection terminals
terminal block
ground wire terminal block
Note
The relays R1 up to R3 are semiconductor re-
lays for pump speed control. A minimum load of
20 W (power consumption of the consumer) is
required for faultless function. The 4.7nF capaci-
tor 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
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

1.2.5 Mains supply
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.

1.2.4 Sensors
earth terminal block
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.

4.3.1 Heat quantity measurement
OHQM: Heat quantity mea-
surement
adjustment range: “OFF”, “ON”
factory setting: “OFF”
Heat quantity measurement is possible if a flowmeter is
used. For this purpose, the heat quantity measurement
option (OHQM) has to be enabled.
The flow rate is measured at V40 (see display channel VSTR).
Antifreeze type and concentration of the heat transfer
medium have to be adjusted in the channels MEDT and
MED%.
Antifreeze type:
0 : water
1 : propylene glycol
2 : ethylene glycol
3 : Tyfocor® LS / G-LS
The flow rate as well as the reference sensors S7 (flow) S8
(return) are used for calculating the heat quantity supplied.
It is shown in kWh in the channel kWh and in MWh in the
channel MWh. The overall heat quantity results from the
sum of both values.
The accumulated heat quantity can be reset. As soon as
one of the display channels of the heat quantity is selected,
the symbol is permanently shown on the display. Press
button SET (3) for about 2 seconds in order to access the
RESET mode of the counter. The display symbol will
flash and the heat quantity value will be set to 0. In order to
finish this process, press the button to confirm.
In order to interrupt the RESET process, no button should
be pressed for about 5 seconds. The controller automatically
returns to the display mode.

Maximum temperature limitation
The controller is equipped with an independent tem-
perature differential regulation for which minimum and
maximum temperature limitations as well as correspon-
ding 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..
Reference sensor for this function:
S4 at Arr 8, 13, 20, 26 (TST2, TFSB)
S3 at Arr 2, 11, 16, 17, 18, 24, 30 (TSTU)
Both switch-on and switch-off temperature differences
DT3O and DT3F are valid for the maximum and mini-
mum temperature limitation.

4.3.4 ∆T-regulation (solid fuel boiler and heat exchange)
Note
The switch-on temperature difference must
be at least 1 K higher than the switch-off
temperature difference.
Note
The controller is also equipped with a non-
adjustable emergency switch-off if the store
reaches 95 °C. The reference sensor is S2 (or
S3 for two store systems).
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 symbol is shown on the display.
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.
