Heating capacity
The unit absorbs energy from the air inlet location ambient conditions. If the
air inlet temperature is low, heating capacity will show variation from standard
conditions.
3 minutes protection
When the unit stops, if you restart the unit or turn on the manual switch, the
unit will not run for 3 minutes. This is built in protection for the compressor.
Heating mode running
If the ambient temperature is too high, to protect the unit, the fan motor will
stop running.
Defrosting
When in heating mode, the unit will defrost automatically. The fan motor will
stop running when the unit is defrosting.

sophisticated electronic devices -
