Starts or stops the unit operation after pre-set time. If RC-1 is used,
the timer setting will be (0.5 - 24 Hr) from the moment the timer is set.
The minimum resolution is 30 minutes.
If RC-2 or later version of remote controls is used, the timer
setting will be (0:00 - 23:50) real time with 10 minutes resolution.
•
After power failure, all pre-set timers are cleared. The system is
forced to STBY mode and the Timer LED indicator is blinked to
indicate the situation. The LED keeps blinking until the timer settings
can be reloaded from a R/C message.
Note: If all timers are inactive, the system will not be forced
OFF after the power failure. The last OPER/STBY status will
be loaded from the EEP instead.
•
When the A/C receives any valid message from a R/C, the current
ON/OFF timer settings will be replaced by the new timer settings in
the R/C message.
Note: The following timer related operations will not affect the
A/C operating mode (Heat/Cool/Auto/Dry/Fan) setting.
•
Set ON/OFF timer
•
Clear ON/OFF timer
•
R/C ON Timer is time-up
•

E.g. When a STBY A/C unit (with Cool Mode setting in its EEP) is
turned on by the ON-TIMER of a R/C with heat mode setting,
the A/C will start in Cool Mode.
