If Tamb<Tset-2℃,compressor, outdoor fan motor will stop running, indoor fan motor will keep low fan speed running.
In this mode, the reversal valve will not power on, the setting temp. range :16℃-30℃.
Protection Functions
Antifreezing Protection
When running in Antifreezing protection, the compressor, outter fan motor, stop running, indoor fan motor runs at low fan speed;
when antifreezing is eliminated and compressor has stopped for 4min, the unit will run at the original status.
HEAT Mode
The conditions and processes of heating
If Tamb≤Tset+2℃,enter into HEAT mode,at the same time, reversing valve,compressor,outdoor fan
start to run, but indoor fan will delay 3min at least to run.
If Tamb≥Tset+4℃,compressor,outdoor fan stop running,the reversing valve will run,but indoor
fan will blow wind after 60sec. at low fan speed.
If Tset+2℃<Tamb<Tset+4℃, the setting range:16℃-30℃.
The conditions and processes of defrosting
Ultra thin split unit series
When Tset+2℃<Tamb<Tset+4℃
it will keep the preceding running status.
When detecting there is frost on the condenser, system enter into defrosting state, at this time, compressor continue to run, the outter
fan motor, 4-way valve, indoor fan motor stop running, the running indicator flash, when detecting the frost on the condenser elimated,
New defrosting mode (Single split type series)
