Characteristics of HEAT mode operation
Mechanism and capacity of HEAT mode operation
■
Mechanism
•
The unit draws in heat from the cold outside air, transfers it indoors and heats the room. The heating capacity of the heat pump mechanism decreases
when the outside air temperature gets colder.
•
The hot air circulation system takes a while before warming up the room temperature.
•
If the outside temperature becomes extremely low, it would be better to use an additional source of heating.
Defrosting
If the outside temperature becomes low and humidity is high, the heat exchanger in the outdoor unit may frost over, which prevents efficient heating.
If
this happens, the automatic defroster is activated and during defrosting the heating operation stops for 5 to 10 minutes.
•
Both indoor and outdoor fans stop and the RUN light (green) blinks slowly (1.5 secs. ON, 0.5 secs OFF) during defrosting.
•
The outdoor unit may give off some steam during defrosting. This is to help the defrosting process and is not a defect.
•
The HEAT operation resumes as soon as defrosting has been completed.
•
Compressor is defective
•
Lack of oil
•
Capacitor is defective
Fuse often blows
RUN light comes on
