3.2 Automatic switching for HUMID HEAT operation room
Outline When the indoor units in both 2 rooms are set to HUMID HEAT operation, priority is given to the
indoor unit starting operation first basically.
However, priority is given to the indoor unit starting operation subsequently under certain
conditions.
Detail 1. When the indoor units in both 2 rooms are set to HUMID HEAT operation, priority is given to
the indoor unit starting operation first (Unit 1), and the indoor unit goes into humidifying
operation while the indoor unit starting operation subsequently (Unit 2) goes into standby
mode.
2. When the humidity of the Unit 1 reaches a target level, the unit which performs HUMID
HEAT operation switches from Unit 1 to Unit 2 automatically.
3. When the temperature decreases in the room of the Unit 1, the Unit 2 goes into standby
mode, then, the Unit 1 starts HUMID HEAT operation again.
Carry out priority room setting to prevent the room of HUMID HEAT operation from switching
automatically.
