11-9. TIMER OPERATION

Timer operation can be performed by setting the wired or wireless remote controller timer. Start and stop times can be set in
10-minute increments within a 24-hour period.
When used in combination with the central control remote controller of the M-NET control system for the outdoor unit, one
program timer can be used for individual timer settings for each group of the central control system. (Each timer setting can
be stored in data memory so timer settings for up to 50 groups can be set individually.)
W Please refer to the MELANS catalog or technical information for details about the central control remote controller.
