Remote Controllers
4.3 2 Remote Controllers
1 indoor unit is controlled by 2 remote controllers from 2 separate locations
This is a convenient system for when you want to operate an indoor unit in the reception room from the office, for
example, or finely operate an indoor unit from a local or remote location. (The same applies to other types of indoor units.)
„
Operation control mode of the indoor unit is last command priority.
„
Remove the front panel of the remote controller and set the main/sub changeover switch on the PC board to “main” for
the main remote controller, and to “sub” for the sub remote controller.
Note:
The remote controller is equipped with a thermostat sensor. If the main and sub remote controllers are mounted in
separate rooms, set the main remote controller so that the thermostat sensor in the remote controller is not used.
