11.6 DUCTED TEMPERATURE AND HUMIDITY PROBE CONNECTION (ACCESSORY)
The supplied temperature and humidity probe allows managing the room temperature and humidity detection in systems
where return detection is not real or satisfying like, for example, systems with partial outside air introduction in the return.
The supplied probe is the duct installation type. It is recommended to position the probe at the centre of the duct for the
most reliable temperature readings.
The connections must be made as indicated in the electrical wiring diagram supplied with the unit. The gure below shows
the probe’s connection terminal board and the position of the jumpers for correct operation of said probe.
