13. Installing controller
13.8 Connecting temperature sensors
The sensor cables can be extended with min. 0.5 mm
2
cables. Total cable length
for each sensor must not exceed 15 m. Boiler temperature sensor must be
installed in a thermometer well in the boiler jacket. Domestic hot water storage
tank temperature sensor must be installed in a thermometer well welded into
the storage tank. Mixing valve temperature sensor should be installed in a
sleeve in a stream of flowing water, however it can also be attached to the pipe,
provided the thermal insulation covers both the sensor and the pipe.
ALL SENSORS MUST BE SECURELY ATTACHED
TO THE MOUNTING SURFACE.
Ensure thermal contact between the sensors and the measured surface. Use
thermally conductive paste. Do not immerse sensors in oil or water. Sensor
cables must be led separately from mains cables. Otherwise, it may affect
temperature measurements. Minimum distance between cables is 10 cm. Do
not allow sensor cables to contact hot surfaces of the boiler and the heating
system. Temperature sensor cables are resistant to temperature up to 100°C.
13.9 Connecting weather compensator
The controller is compatible with CT6-P weather compensator. Install the
weather compensator on the coldest wall of the building, usually northern
side, under roof. Do not expose to direct sunlight or rain. Install the sensor at
least 2 meters above the ground, at least 1.5 m from windows, chimneys and
other heat sources which may affect temperature measurements. Use min.
0.5 mm
2
cables with length up to 25 m. Cable polarity is not relevant. Connect
the other cable end to the controller terminals. Mount the sensor on the wall
with mounting screws. Mounting screw holes can be accessed by removing the
enclosure cover.
13.10 Checking temperature sensors
The temperature sensors may be checked by measuring resistance at a specific
temperature. If any significant differences are observed between the measured
resistance and the values in the table below, replace the sensors.

13.11 Connecting mixing valve room thermostat
When the room thermostat contacts are open, the mixing valve circuit tempe-
rature setpoint is reduced by the value of the mixing valve temperature setpoint
decrease by the thermostat.
The parameter can be modified in:
Mixing valve 1-5 settings > Mixing valve room thermostat
The selected parameter should result in room temperature decrease after the
thermostat is tripped.
If the room thermostat is installed, select a correct
Select thermostat
