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 sec. ON, 0.5 sec. 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.
Air-conditioner operating conditions
■
Use within the following operational range. Operating outside of this range may result in the protection devices being activated, preventing the
unit from working.

surface of the indoor unit, leading to water drips.
Power Blackout Auto Restart Function
■
What is power blackout auto restart function?
•
Power blackout auto restart function is a function that records the operational status of the air-conditioner immediately prior to it being switched off
by a power cut, and then automatically resumes operations at that point after the power has been restored.
•
The following settings will be cancelled:
