Connection of indoor sensor
The indoor sensor is positoned centrally at the most open position possible in
the house, ideally in a hall between several rooms or in a stairway. This position
will allow the sensor to register an average temperature for the house.
Lead a three conductor cable (minimum 0,5 mm2 ) between the boiler and
indoor sensor. Then mount the room sensor at approx two thirds wal height.
Connect the cable to the indoor sensor and to the boiler.
Important! The wires must be correctly connected for the sensor to function.
Markings 1.2 and 4 on the heat pump match the markings on the sensor.
Connection primary flow sensor
Fit the sensor to the primary flow pipe, ideally after the heating circuit pump.
The sensor probe is in the sensor front section, see diagram.
- Fasten the sensor in place using the enclosed tensioning band.
- Ensure that the sensors has good contact with the pipe. Contact paste
can also be aplied to the sensor’s front, between the sensor and the
pipe.
- Important! Isolate the sensor, for example using pipe insulation.
- Connect the cables to the boiler’s terminal block.
!
Do not permanently mount the sensor
cable before you have tested and found the best
position.
