6.7 Setting up an external temperature sensor
You can connect one external temperature sensor. It measures the indoor or
outdoor ambient temperature. We recommend to use an external temperature
sensor in the following cases:
Indoor ambient temperature
▪
In room thermostat control, the dedicated Human Comfort Interface (BRC1HHDA
used as room thermostat) measures the indoor ambient temperature. Therefore,
the Human Comfort Interface must be installed on a location:
-
Where the average temperature in the room can be detected
-
That is NOT exposed to direct sunlight
-
That is NOT near a heat source
-
That is NOT affected by outside air or air draught because of, for example, door
opening/closing
▪
If this is NOT possible, we recommend to connect a remote indoor sensor (option
KRCS01-1).
