10-1. Product functions

• This controller can control up to 50 air conditioners and LOSSNAY with a daily schedule either
collectively or in groups.
• This controller has only a schedule setting function and must be used with another system
controller. When used independently, only the air conditioner's ON/OFF status and error status
will be monitored (operation status display). In addition to schedule setting, the units can be
turned ON/OFF and stopped and the timer can be reset either collectively or in groups with switch
operations.
The details of the functions are listed below.
