5. Special remarks

·
3 minutes protect after compressor stop
For protect compressor, there are at lest 3 minutes stopping after compressor stop.
·
5 minutes protect
Compressor must run 5 minutes at least once running. In the 5 minutes, compressor will not stop
even the room temperature reach the setting point unless you use remoter to turn off the unit(all
indoor unit be turned off by user).
·
Cooling operation
In cooling mode, the temperature can be set between18℃—32℃ .
The fan of the indoor unit will never stop running. It remains running even if the compressor stops working.
·
Heating operation
Since the air conditioner carries out the heating operation by drawing on the heat of the outside air (through
heating pump), the heating capacity may decrease if the
temperature outside the room is too low. If the heating effect is not so satisfying, use some other heating
device together.
·
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 high enough temperature. That is because cold air prevention system
is operating.
·
Defrosting
When the outdoor temperature is too low, frost or ice may form in 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),a few minutes later, the
defrosting is over, and the heating operation restarts.
·
Blow out the survival heating air
When stop the air conditioner in normal operation, the fan motor would run in low speed for a while to blown
out the survival air.
·
