Principle:
Air conditioner absorbs heat in the room and transmit to
outdoor and discharged, so that indoor ambient temperature
decreased. It's cooling capacity will decrease by the increase
of outdoor ambient temperature.
Anti-freezing Function:
If the units is running in COOL mode and in low temperature,
there will be frost formed on the heat exchanger, when
indoor heat exchanger temperature decreased below 0 C,
the indoor unit micro-computer will stop compressor running
and protect the unit.
Principle:
1. Air conditioner absorbs heat from the outdoor and transmit
to indoor and evaporated, so that indoor temperature
increased. Its heating capacity will decrease by the
decrease of outdoor ambient temperature.
2. If outdoor temperature got lower, please operate with
other heating ventilating equipments.
Defrosting:
1. When outdoor temperature is low but high humidity, after a
long while running, frost will form on outdoor unit, that will
effect the heating effect. At this time, the auto defrosting
function will act, and the heat running will stop for 8-10
minutes.
2. During the auto defrosting function, both the fan motors of
indoor unit and outdoor unit will stop operate.
3. During the defrosting function, the indoor indicator flashes
and the outdoor unit may emit vapor. This is due to the
defrosting, it is not malfunction.
4. After defrosting finished, the heating will recover
automatically.
Cold Draft Prevention:
In "HEAT" mode, the indoor blower will no act at the
following 3 status, while the heat exchanger haven't achieve
the certain temperature. This is to prevent cool air blowing.
(Within 2 minutes).
1. Heating starts.
2. After auto defrosting finished.
3. Heating under low ambient temperature.
Gentle Breeze
In the following situation, the indoor unit may blow gentle
breeze, and the guide louver rotate to a certain position:
1. In “Heat” mode, the unit turned on, the compressor does
not arrive the starting condition
2. In “Heat” mode, the temperature arrive at the setting
value and the compressor stop running about 1min.
