8.3. Heating Mode Operation
When selecting the Heating Mode Operation, the unit will operate according to the setting by the Remote Controller and
the operation is as the following.
Time Delay Safety Control
Over Load protection Control
When temperature of indoor heat exchanger rises to 51℃, outdoor fan will stop
when temperature of indoor heat exchanger falls to 49℃, outdoor fan will restart.
When temperature of indoor heat exchanger rises to 65℃ or above, compressor stops, and will restart 4 minutes later.
4-way valve control
Anti-reversing Control
If the compressor stopped by switching off, turning off by remote controller, or power off, it will not
restart within 3 minutes.
When room temperature reaches the set temperature on the remote controller, compressor stops and will not
restart within 4 minutes.
3 minutes after the compressor stopped, indoor fan will stop for 1 minute. Then indoor fan will resume
operation with the speed at super low
.
Compressor
Stops
Compressor Restarts
4 minutes later
Indoor Heat Exchanger ≥65℃
Compressor
Stops
Compressor Restarts
3 minutes later
Compressor runs ≥5 min
△T≤5℃ last for 2 min
△T= intake air temperature - evaporator temperature
If the compressor has been continuously running for 5 minutes or longer, and the difference of temperature between
intake air and evaporator is continuously lower than 5.0℃ or below for 2 minutes, the compressor will stop , and then
restart 3 minutes later.(Time Delay Protection Control is effective.)
During heating mode operation,4-way valve is at “open”mode.
During heating mode operation,if the unit turned off, the 4-way valve will remain
at “open”mode for 5 minutes.
Warm Booting Control
When turning on the unit by heating mode operation,indoor fan
will be activated when temperature of indoor heat exchanger
reaches 30℃. (See the figure on the right)
Warm boot operation ends when temperature of indoor heat
exchanger reaches 34℃.
