8.5.11. 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.
8.5.12. 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.
8.5.13. 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.
8.5.14. Hot Start Control
•
Hot Start Control is to prevent cool air discharge into the room when heating operation start.
•
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 or operation over 4 minutes.
