Protection Functions
Overcurrent Portection
When the system current is tested higher than 15A, only fan will run. After 3 minutes, the whole unit will run in the old
mode, if the overcurrent cannot be eliminated, the whole unit will stop, and can be restarted by the wireless remote control.
Antifreezing Protection

When the antifreezing protection is finished, the compressor stopped for 3Min, the unit will return to the old mode.
If Tamb
≥
Tset+1
℃
, COOL mode will act, compressor and outdoor fan will run at low speed, indoor fan will run at the set spee d.
If Tamb ≤ Tset － 1 ℃ ,tunit will stop , compressor will stop and then outdoor fan will delay 15sec and stop.Indoor fan will run at set speed.
After power is on, no matter when compressor is started, the time span between the startups cannot be less than 3 minutes.
