Thermo OFF point by the inlet air temp. (Only in SA temp. control mode)
This setting is only activate when SA temperature control is selected. The compressor of outdoor unit is forced to stop when the
inlet air temp. is close to the setting temp. to reduce frequent ON/OFF cycling under low heating/cooling load conditions.
The thermo OFF point can be set by the SW3-4 and SW3-5 as below.
