Operation Contents
Program Dry
The Program dry function of the system repeats the weak cooling
operation of the system intermittently to dehumidify the room without
dropping the room temperature as much as possible for the
prevention of excessive cooling.
Program Dry Operation
• The microcomputer is in automatic temperature and fan speed control. Therefore, temperature or
fan speed settings cannot be made or changed while the air conditioner is in operation.
Setback
The Setback feature will maintain the space temperature in a specic range during unoccupied
periods.
Note
• This function will temporarily start an indoor unit that was previously turned off by the user or
turned off from a schedule event/off timer.
• This function is by default enabled in Cool mode and Heat mode. This function can only be
enabled/disabled by the system installer.
For example:
• If the room temperature drops below 10°C, heating is started automatically. As soon as 12°C
is reached, the controller returns to its original status.
• If the room temperature goes above 35°C, cooling is started automatically. As soon as 33°C is
reached, the controller returns to its original status.
The differential can be adjusted in the Setback conguration menu (see page 38). The setback
temperature can be set during the unit is turned off on basic screen when the unit is turned off or
set in the schedule.
