Mode Hierarchy
Outline
There are two modes; the one is the normal operation mode and the other is the forced operation
mode for installation and providing service.
Detail
There are the following modes; stop, cooling (includes drying), heating (includes defrosting)
Note:
Unless specified otherwise, dry operation command is regarded as cooling operation. An indoor fan
operation is not used with a multiple indoor unit. A forced fan command to the indoor unit from the
outdoor unit is made during forced operation.
Determine Operation Mode
The system detects the operation mode command which is set by each room in accordance with
the procedure, and determines the operation mode of the system.
The following procedure is taken when the modes conflict with each other.
*1. The system follows the mode which is set first. (First-push, first-set)
*2. For the rooms where the different mode is set, standby mode is activated. (The operation lamp
blinks.)
