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.
Sensor positions:
•
M
1
= Measuring point for flow temperature sensor top
•
C
1
= Sensor cable retaining clip
▶ 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.

Connection of the storage tank to the heat pump and
heating system
▶ When sizing the heating system expansion vessel, take the storage
tank volume into consideration.
▶ For further information about system layout refer to installation
instructions of main appliance.

connection to the heat pump
▶ Ensure pipe work is adequately supported
▶ Ensure that the correct connections are made to the storage tank.
▶ Check all connections for tightness.
Ensure that the sensor area has contact with the sensor
pocket area for the sensor‘s full length.
For information on the sensor refer to the documentation of
your heat pump or of the control unit.
DANGER:
Risk of fire from soldering and welding!
▶ Take suitable safety measures when soldering and
welding.
NOTICE:
Risk of damage to non heat-resistant installation
materials (e. g. plastic piping)!
▶ Use installation material which is heat resistant to
80 °C.
