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. .
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.
a. Set ON/OFF timer
b. Clear ON/OFF timer
c. R/C ON Timer is time-up
d. R/C OFF 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 an R/C with heat mode setting, the A/C will start in Cool Mode.
