(b) Operation control function by the wired remote controller
(i) The following is the sequence of operation for the remote controller operation mode switch.
(ii) CPU reset
This functions when the " inspection " and " filter reset switch " on the remote controller are pushed simultaneously. It
operates in the same manner as the power reset.
(iii) Power outage compensation function.
¡
This is enabled by setting dip switch SW3 on the remote control circuit board to ON.
¡
It records the normally used remote control modes. Once power has been restored, it restarts operation by using the
contents of the memory. Note that the stop positions for auto swing and the timer mode are cancelled.
