8.3. Heating Mode Operation
•
When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
•
When the setting temperature is reached during heating operation, the compressor stops and it will not start for 4 minutes.
•
The compressor will start automatically if it has stopped for 30 minutes even if the room temperature is between the compressor
ON temperature and OFF temperature.
ON temperature and OFF temperature.
•
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 continuously 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.
heat exchanger is 5°C or less for 2 minutes, compressor will stop and restart automatically.
(Time Delay Safety Control is valid).
s
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. (Except Deicing operation)
•
When the unit is switched to “OFF” during Heating operation, 4-way valve stay at Heating position for 5 minutes.
•
When compressor stops (reaches room temperature), outdoor fan will operate for 30 seconds.
(30 seconds Forced Operation).

Hot Start Control
Anti Cold Draft Control
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 rises to 39°C.
•
This operation is to prevent the Cold Draft during Heating mode operation.
•
The operation will start when compressor OFF (Thermo OFF) during Heating operation.
•
For the first 30 sec from compressor OFF (Thermo OFF), Indoor fan speed will operate accordingly to the Indoor heat
exchanger temperature as shown below:
exchanger temperature as shown below:
Note: SSLo: Fan will be running at Lo speed with Indoor heat exchanger temperature 1.5 sec ON and 5.5 sec OFF.
•
After 30 sec. from compressor OFF (thermo OFF), Indoor fan will run at SSLo speed only.
•
Anti Cold Draft Control will stop when:
−
Intake temperature < set temperature -1.5°C. (Time Delay Safety Control 4 minutes waiting is valid)
−
After 30 minutes time saved control.
