Once connected to the k.Air controller and enabled, th- Tune allows the user to control the room temperature and relative humi-
dity (
NOTE: the room humidity set point can however only be set on the pGDE terminal) and change some settings, such as
operating mode and time bands. Depending on the model, it can be equipped with a temperature probe or with a temperature
and humidity probe.
