8.5.9. Compressor Overload Protection Control
Outdoor Fan Control
• 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.
Compressor high pressure protection
• If the indoor heat exchanger becomes 65°C or more, the compressor will stop and restart automatically.
(Time Delay Safety Control - 4 minutes waiting).
• This is to reduce the pressure, as to reduce the indoor heat exchanger temp. Nevertheless, is to protect the compressor
from overload of too high temperature.
8.5.10. 4-Way Valve Control
• 4-way valve always on during Heating operation. (except deicing operation)
• When the unit is switched off by remote control during Heating operation, the 4-way valve stay at Heating position for 5 minutes.
• This is to prevent the refrigerant flow process sound for being occur.
8.5.11. Outdoor Fan Motor Control
• When compressor stops (reaches room temperature), outdoor fan will operate for 30 seconds (forced operation).
• This is to release the heat and to obtain the lowest pressure as fast as possible.
