Operating principle and special functions for heating

Notices for use
Principle:
The air conditioner absorbs heat in the room and sends it outside, so as the indoor
ambient temperature decreases, the cooling capacity will increase or decrease based
on the outdoor ambient temperature.
Anti-freezing function
If the unit is running in COOL mode and on a low temperature, frost will form
on the heat exchanger. When the indoor heat exchanger temperature goes below 0 °C,
the indoor unit’s microcomputer will stop runnig the compressor to protect the unit.

Maximum cooling 32/23 48/-
Minimum cooling 21/15 10/-
Maximum heating 27/--- 24/18
Maximum heating 20/--- -15/-6
The operating temperature range (outdoor temperature) for cooling unit is 10 ºC à 48 ºC
(50 ºF à 118 ºF) for cooling and heating unit is -15 ºC à 48 ºC (5 ºF à 118 ºF).
Principle:
* The air conditioner absorbs the heat in the room and sends it outside will increase, its
heating capacity will decrease by outdoor ambient temperature.
So as the indoor ambient temperature increases, so does the room heating capacity.
* If the outdoor temperature decreases, please use other heating/ventilating equipment.
Defrosting:
* When the outdoor temperature is low but the humidity is high, and the unit has been
running for a long period of time, frost will form on the outdoor unit.
The heating will stop running for 8 - 10 minutes while the auto-defrost is functioning.
* While auto-defrosting, the fan motors on both the indoor and outdoor units will stop.
* While defrosting, the indoor indicator flashes, and the outdoor unit may emit vapor.
This is due to the defrosting, and is not a malfunction.
* After the defrosting has finished,the heating will re-start automatically.
Anti-freezing function:
While in "HEAT" mode, in conjunction with one of the following statues, the indoor heat
exchanger hasn't reached the set temperature, the indoor unit will not run, in order to
prevent cool air from blowing. (Within 3 mins)
1.Heating starts.
2.After auto-defrosting ends.
3.Heating in low temperatures.
The unit's climate type can be found on the nameplate.
