c. overload protection If it detects the system current surpass the designed 13 A for continuous 3 minutes, the machine goes into fan mode only, when 3 minutes passes and it detects the current no more than 13 A, it will be back to original state.

b. anti high temp. In heating mode, if it detects T 56 (58 can be selected), outdoor motor will stop. If T 53 , outdoor motor will be back running. c. blowing surplus heat In heating mode, when set temp is reached, the compressor stops first,15 seconds later out- door fan stops, the indoor motor blows 30 seconds (60 seconds can be selected) at low speed.

Cooling & heating AUTO mode: in AUTO mode, when the machine is switched from heating mode to the other modes, reversing valve becomes inactive in 90 seconds. Cooling only AUTO mode: there is no heating function in this mode. (3) protections It is same as the one in cooling or heating mode.
