a. OPT≥62
℃
, unit stops working for overload protection.
b. OPT
＜
55
℃
, after compressor stopped for 3 min, can the unit be started to operate.
2). When OPT≥55
℃
, the compressor will be frequency limited/reduced for over load protection.

℃
, unit stops working for overload protection.
b. IPT
＜
55
℃
, after compressor stopped for 3 min, can the unit be started to operate.
