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).
▪
Setup: For installation instructions, see the installation manual of the remote
indoor sensor, and the addendum book for optional equipment.
▪
Configuration: Select room sensor [9.B].
INFORMATION
The external outdoor ambient sensor data (either averaged or instantaneous) is used
in the weather-dependent control curves and in the automatic heating/cooling
changeover logic. To protect the outdoor unit, the internal sensor of the outdoor unit
is always used.
