Room temperature sensor

Contact your installer if you wish to supplement your heat pump installation with a room
temperature sensor, see the "References" section.
The room sensor is an accessory that is used to set a desired indoor temperature. It can be
installed in the house where the room temperature is relatively constant, not in a hallway,
kitchen or a room with alternative heating. On the room sensor you can set the desired room
temperature and view the outdoor temperature.
The room temperature sensor has a temperature sensor that provides a further value
that the control computer can use when calculating the supply temperature. The influence
of the room sensor in the calculation can be set in the menu HEAT CURVE-> ROOM
FACTOR. Default setting for ROOM FACTOR is 2 but can be adjusted from 0 (no impact) to
4 (large impact).
The difference between the desired and actual indoor temperature is multiplied by the set
value for ROOM FACTOR. The set point on the heating system's supply line increases or
decreases with the result depending on whether there is a deficit or surplus of heat. The table
below shows examples of how the set point for the supply line is affected at CURVE 40 with
different settings for ROOM FACTOR.
In the event of a heating deficit:
