2. Error detection method

• Judge insufficient refrigerant

amount by detecting the

temperature differnce between

indoor heat exchanger (ThI-R)

and indoor return air (ThI-A).

• It detects at initial startup in

cooling or dehumidifying

mode after power ON.

(In case of model 71 it cannot

detect)
