Special Remarks
●
3 minutes protection after compressor stop
To protect compressor, it will be to be continue off for at least 3 minutes once it has stopped.
●
5 minutes protection
Compressor must run at least for 5 minutes once it starts running. In this 5 minutes, compressor will not stop
even if the room temperature reaches the set point unless you use remote control switch to turn off the unit
(all indoor unit can be turned off by user).
●
Cooling operation
The fan of the indoor unit will never stop running in cooling operation. It remains running even if the
compressor stops working.
●
Heating operation
Heating capacity depends on external factors as outdoor unit temperature. Heating capacity might decrease if
outdoor ambient temperature is too low.
●
Anti-freezing function during cooling
When the temperature of the air from the indoor outlet is too low, the unit will run for some time under the
fan mode, to avoid frost or ice forming in the indoor heat exchanger.
●
Cold air prevention
In several minutes after the heating mode is started, the fan of the indoor unit will not run until the heat
exchanger of the indoor unit reaches a certain temperature to prevent cold draft.
●
Defrosting
When the outdoor temperature is too low, frost or ice may form on the outdoor heat exchanger, reducing
heating performance. When this happens, a defrosting system of the air conditioner will operate. At the same
time the fan in the indoor unit stops (or runs at a very low speed in some cases), to prevent cold draft. After
defrosting is over, the heating operation and fan speed restarts.
●
Blowing out the residual heating air
When air conditioner is stopped during normal operation, the fan motor will run with low speed for a while to
blow out the residual heating air.
●
Auto restart from Power Break
When the power supply is recovered after power break, all presets are still effective and the air conditioner will
run according to the previous setting.
