Single operation check for outdoor fan

A single operation of the outdoor fan can be confirmed by handling the service switch SW800, SW801. Use this method to check whether there is trouble or not on the fan.

[Method]

(1) Check D800 to D804 are turned off (or rapid flashing) and D805 is turned on. When D800 to D801 flash slowly or D805 flashes, push and hold SW800 and SW801 for 5 seconds or more simultaneously. In the result, D800 to D804 are turned off (or rapid flashing) and D805 changes from flashing to lighting.

(2)Push and hold SW800 for 5 seconds or more. D804 changes to slow flashing.

(3)Push SW800 and stop it at LED display of the following “Outdoor fan single operation”.

: ON, : OFF : Rapid flashing

(4)Push SW801 and then stop it at the position where D805 flashes rapidly.

(5)Push and hold SW801 for 5 seconds or more. In the result, D804 changes to slow flashing, D805 changes to lighting and the fan rotates.

(6)The fan stops when pushing long SW800 and SW801 for 5 seconds or more simultaneously or when 2 minutes passed.

*If an unknown point generated on the way of the operation, push and hold SW800 and SW801 for 5 seconds or more simultaneously. You can return to the item (1).
