External sensor
When an optional external ambient
sensor is connected, the type of the
sensor must be set. See
.
▪ 0 (No)(default): NOT installed. The
thermistor in the user interface and in
the outdoor unit are used for
measurement.
▪ 1 (Outdoor sensor): Installed. The
outdoor sensor will be used to
measure
the
outdoor
ambient
temperature.
Remark:
For some
functionality, the temperature sensor
in the outdoor unit is still used.
▪ 2 (Room sensor): Installed. The
temperature sensor in the user
interface is NOT used anymore.
Remark:
This value has only meaning
in room thermostat control.
Digital I/O PCB
Modification of these settings is only needed when the optional
