14.10 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.
14.11 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.
14.12 Hot Start Control
•
Hot start control is to prevent cool air discharge into room when heating operating starts.
•
Hot start is executed after heating operation starts and deice operation is completed.
•
Indoor fan control during hot start is shown below:
Indoor Pipe Temperature
Indoor Fan
≤
30°C
OFF
30°C < t
≤
34°C

•
When indoor pipe temperature over 34°C or maximum 240 seconds, hot start is completed.
•
During hot start and for 30 seconds after hot start completed, intake thermostat is ignored and no Thermo OFF.
14.13 Cold Draft Prevention Control
•
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:
•
After 30 sec. from compressor OFF (thermo OFF), Indoor fan will run at SSLo speed only.
•
Anti Cold Draft Control will stop when:
o
Intake temperature < set temperature. (Time Delay Safety Control 4 minutes waiting is valid)
o
30 Minutes Time Save Control activates.
