Anti-cool wind function:
In "Heat" mode, under the following three kinds of state, if indoor heat exchanger doesn't
arrive at certain temp., indoor fan will not act, in order to prevent cool wind blowing(within
2 mins):
1. Heating starts. 2.After Auto Defrost finished. 3.Heating under the low temperature.
The operating temperature range (outdoor temperature) for cooling unit is69.8℉~109.4℉
for cooling and heating unit is 19.4℉－１０９．４℉.

Working principle and special functions for heating
Principle:
Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that
indoor ambient temperature decreased, its cooling capacity will increase or decrease by
outdoor ambient temperature.
If the unit is running in COOL mode and in low temperature, there will be frost formed
The Surplus Heat Blowing function:
when unit stop running, after the heating temperature arrived, indoor unit runs at setting
fan speed for 60s.
on
the heat exchanger, when indoor heat exchanger temperature decreased below
32 , the
indoor unit microcomputer will stop compressor running and protect the unit.
℉
Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase
room temperature. This is the heat pump heating principle, its heating capacity will be
reduced due to outdoor temperature decrease.
If outdoor temperature becomes very low, please operate with other heating equipments.
