Trial Operation and Field Settings
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.
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.
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.)
Only one room can be set as the priority room.
