The unit determines its operation mode by the outdoor temperature if:
▪ Operation mode = Automatic , and
▪ Operation mode schedule = Reversible .
The unit determines its operation mode in such a way that it will always stay within
the following operation ranges:
▪ Space heating off temperature
▪ Space cooling off temperature
The outdoor temperature is time-averaged. If the outdoor temperature drops, the
operation mode will switch to heating and vice versa.
If the outdoor temperature is between the Space heating off temperature
and the
Space cooling off temperature
, the operation mode remains
unchanged.
Operation range
Depending on the average outdoor temperature, the operation of the unit in space
heating or space cooling is prohibited.
