12.5.15. Anti Cold Draft 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:
- Intake temperature < set temperature. (Time Delay Safety Control 4 minutes waiting is valid)
- 30 Minutes Time Save Control activates.
12.5.16. Deicing Control
Deice starts to prevent frosting at outdoor heat exchanger.
• Normal Deicing
Deice operations detection commences after 30 minutes of Heating operation starts or 60 minutes after previous deice
operation. If the TRS (Thermal Reed Switch) senses the outdoor piping temperature drops to -3°C (TRS CLOSE) or less for 50
sec. continuously during compressor is in operation, deice will start.
(There is no detection during Outdoor Fan stops.)
• Overload Deicing
During heating operation, if the outdoor Fan OFF duration (due to overload control) is accumulated up to 60 minutes and after
compressor starts for 1 minutes, deicing starts.
• Deicing ends when
1. 12 minutes after deicing operation starts;
2. TRS senses the outdoor piping temperature rises to 4°C (TRS OPEN).
Deicing will not end immediately as time delay (Td) is valid as shown below.
• Once deicing operation starts, it will not end for 60 seconds.
• After deicing operation, compressor stops for 30 seconds and 4-way valve stays at cooling position for 10 seconds.
