5.3 Outdoor Unit
5.3.1 Priority Room Setting
Outline
The indoor unit for which priority room setting is applied takes priority in the following cases.
Operation mode priority
The operation mode of the prioritized room takes precedence. For example, when the prioritized
indoor unit starts cooling operation, the other indoor units which have been in heating operation
enter the standby mode. Heating operation will resume if the prioritized indoor unit stops cooling
operation.
Priority during POWERFUL operation
The electronic expansion valves are controlled to provide more capacity to the prioritized room
and the capacities for the other indoor units will be slightly reduced.
OUTDOOR UNIT QUIET operation priority
When the OUTDOOR UNIT QUIET operation is selected in the prioritized room, the outdoor unit
runs quietly.
Without priority room setting, OUTDOOR UNIT QUIET operation starts only when the function is
set for all the operating indoor units.
Procedure
1. Turn the circuit breaker off before changing the setting.
2. Turn on the one of the switches of the SW4 on the service monitor PCB.
Only one room can be set as the priority room.
3. Turn the power on.
