(3) Operation control function by the wired remote controller

(a) Remote controller operation mode switch switching sequence
DRY
(b) CPU reset
If the "GRILL" button and "CHECK" button on the remote controller are pressed at the same time, this function is activated.
The system will behave as same way as power supply reset.
(c) Power failure compensation function
• By setting the remote control functions, setting of the "POWER FAILURE COMPENSATION SETTING" is enabled.
• The remote controller's status is always stored in memory, and after recovering from a power failure, operation is resumed
using the memory contents. However, the memory for auto swing louver stopping position is deleted and timer mode is
cancelled.
Operation program on the weekly timer is not deleted and the calender starts from Friday, however, all day are set as
holidays when recovered. It means that the weekly timer will not activate unless holiday setting is enabled.
• Contents stored in memory for power failure compensation are as follows.
