Room temperature sensor
9.1
Contact your installer if you wish to supplement your heat pump installation with a
room temperature sensor, see section ”13 References”.
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.
