11.8 Protections
11.8.1 Indoor Coil Defrost Protection
During Cool Mode/Dry Mode, this protection prevents freezing of the indoor heat exchanger.
When ICT <= 0 C for continuous 3 mins, COMP and OFAN will stop and IFAN will run at its setting
speeds.
The system will resume its previous status if the protection is cleared and COMP OFF time is 3 min.
(COMP OFF time will be 4 min during the 6 min ON and 4 min OFF cycling during Dry Mode)
11.8.2 Indoor Coil over Heating Protection
During Heat Mode, this protection prevents abnormal high pressure.
When ICT reaches 58C, OFAN will stop operating and resume operating if the ICT go to normal.
11.8.3 Over Current Protection
Detect an input current by the CT during the COMP is running.
If the current is high than 22A for continuous 3 sec, COMP and OFAN will stop, IFAN will run at
setting speed.
The system will resume its previous status if the protection is cleared and COMP stops for 3 min.
If the unit stops as such protection for 6 times,(the counter will be cleared after the compressor has
run for 6min), it cannot resume running automatically and display malfunction, it can resume by
pressing ON/OFF.
11.8.4 Outdoor Coil Deicing Protection
This protection is for Heat Pump Only
This protection is carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor
heat exchanger temperature must be more than its setting values when finishing the deicing
protection.
In the deicing protection, IFAN is forced OFF.
11.8.4.1 Deicing Starting Conditions
The starting conditions must be made with the room air temperature (RAT) and indoor coil
temperature (ICT) and the trend of changing. Under the conditions that the system is in heating
operation, after the time for defrosting is judged to be satisfied, the deicing operation will start.
