5.3.4. Connecting the controller
After the wires are secured to prevent accidental ripping, connect the
power supply cable on the side of the controller to the
IN terminals ( L, ,
N ). Then connect the cable to a 230V/50 Hz power outlet with a grounding
pin.

5.2. Operation with the HDW over CH priority
switched on
If the HDW over CH priority function is switched on, then activation of the
pump in the HDW circuit depends not only on the setting and on the
temperature measured by the
SR3 sensor, which is installed in the HDW
tank, but also on the temperature measured by the SR1 (CH) sensor.
If the HDW over CH priority function is switched on and if a situation occurs
where two HDW pumps and a CH pump should be in operation at the same
time (provided that the
SR1 (CH) temperature sensor is connected and that
the power supply cable of the CH pump ( OUT1 ) is connected), then the
operation of the HDW pump has a priority.
The way it works is that the HDW pump is started first and is in operation
until the desired temperature is reached and then the CH pump is started.
What the HDW over CH priority function also does is that if the temperature
measured by the
SR1 (CH) sensor is lower than the temperature measured
by the SR3 (HDW) sensor, then the HDW pump does not start. This prevents
cooling down water in the HDW tank.
5.3.2. Mounting the sensor
On the controller side, the temperature sensor must be connected to the
SR3 terminals and then installed in the hot domestic water tank. The
sensor must not be immersed in liquids or installed at the fireplace smoke
outlets. The maximum measured temperature value is 99 °C.
5.2.1. Manual mode - continuous operation
In order to manually switch on the circulating pump (regardless of
thecurrent temperature at the SR3 (HDW) sensor), press the "
C
" button
and hold it for 3 seconds.
5.3. Installation
5.3.1. Mounting the controller
The controller must be mounted on a wall or another support using two
screws (the concrete anchors with screws are delivered with the
controller). The cables extending from the controller must be fixed to the
wall with cable clips.
5.3.3. Connecting the power supply cable of the HDW pump
In the controller, the HDW pump's cable must be connected to the OUT4
terminal ( L , , N ). In the pump, connect the green or yellow-green wire
(grounding or protective zero) to the " " terminal. Connect the blue wire
to the "
N " terminal and the brown wire to the " L " terminal.
5.4. Operation of the controller
5.4.1. Switching the controller on
Set the power supply switch in the " I " position. After power is
switched on, all segments of the display light up for about 2 seconds. Then
the controller indicates the current temperature of measured by the
sensor.

5.4.2. Changing the temperature
Press the "
C
" button. When the set temperature indicator in the HDW
circuit starts blinking, use the "+" or "-" button to set the desired
temperature. Once the desired temperature value is set, it must be
confirmed (do not forget to do so) within 10 seconds by pressing the
"
OK " button. Otherwise, the changed value will not be saved and the
controller will return to the previous setting.
5.4.3. Changing the hysteresis
Press the "
C
" button under the temperature setting. The digits begin to
blink and indicate the value of the current setting. Display the hysteresis
setting (
HI ) by pressing the "
C
" button again. Using the "+" or "-" button,
set the required hysteresis value in the range of 2°C to 10°C (with a 2 °C
increment). After the value is set, approve it (within 10 seconds) by
pressing the "
OK " button. Otherwise, the changed setting will not be
saved and the controller will return to the previous setting.
Example: If the temperature setting is 40°C and the hysteresis is 4°C, the
pump will start at 38°C and will stop at 42°C.
5.4.4. Switching on the priority function
Press the button under the temperature setting. The digits begin to
blink and indicate the value of the current temperature setting. Display
the hysteresis setting (
HI ) by pressing the button again. Then press
the button again to display the HDW pump operation indicator ( ).
Using the "+" and "-" buttons, switch on ( - frame) or switch off ( -
no frame) the priority function.

NOTE: The ambient temperature in the place where the
controller is installed must not exceed 40°C.
OTE: The wires and cables may be connected only when the
power supply is cut off.
