Fitting the temperature sensor

▶ Slide the temperature sensor into the sensor pocket, use heat paste
to ensure a good contact. Fit the sensor cable into the cable retaining
clip with a small loop to ensuring the cable is not pulled tight.
Ensure that the sensor area has contact with the sensor
pocket area for the sensor's full length.
Sensor positions:
• M = Measuring point for flow temperature sensor top
1
• C = Sensor cable retaining clip
1
For information on the sensor refer to the documentation of
your heat pump or of the control unit.
▶ Lay the sensor lead through open cable retaining clip, ensuring that a
small loop of cable exists between the clip and the sensor, and close
the clip firmly on the cable.

heating system
DANGER: Risk of fire from soldering and welding!
▶ Take suitable safety measures when soldering and
welding.
▶ When sizing the heating system expansion vessel, take the storage
tank volume into consideration.
▶ For further information about system layout refer to installation
