3) Heating Mode Operation
Heating in operation according to Remote Control setting.
• When the compressor is stopped by Power Switch, Remote Control or there is a power failure, it restarts after 3
minutes when the Power Switch, Remote Control is turned ON or the power supply is resumed.
• When the setting temperature is reached during heating operation, the compressor stops and it will not start for
4 minutes.
• Indoor Fan stops for 1 minute after 3 minutes compressor stops. Then, it will operate with SLo fan speed.
• If the temperature of the indoor heat exchanger rises to 51°C, Outdoor Fan stops.
The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.
• If the indoor heat exchanger becomes 65°C or more, the compressor will stop and restart automatically.
(Time Delay Safety Control – 4 minutes waiting)
• If the compressor is operating continually for 5 minutes or longer and temperature difference between intake air and
indoor heat exchanger is 5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid).
∆ T = Indoor heat exchanger temperature – intake air temperature
This is to protect reverse rotation of the compressor when there is a instantaneous power failure.
• 4-way valve always ON during Heating operation.
• When the unit is switched to "OFF" during Heating operation, 4-way valve stays at Heating position for 5 minutes.
When Heating operation starts, Indoor Fan will not start until the indoor heat exchanger reaches 30°C as diagram
shown.
Hot Start is completed when indoor heat exchanger reaches 41°C.
