9-3-2. Various settings on outdoor unit (Existing piping etc.)
(1) Service switch setting
Various settings are available by setting service switches.
[Operating method]
1) Check LED display is the initial status. If it is not so, set the initial status.
2) Push and hold SW01 for 5 seconds or more and then check D804 flashes slowly.
3) Push SW01 several times and then stop it at the LED display of function item to be set up.
: ON,
: OFF,
: Rapid flashing (5 times/second)
4) Push SW02 so that D805 will flash rapidly.
5) Push and hold SW02 for 5 seconds or more. D804 changes to slow flashing, D805 changes to lighting and
then various settings are validated.
6) When you want to continue the settings, moreover repeat items from 3) to 5).
7) To invalidate various settings, execute items 1) to 3), push SW02 and then turn off D805.
8) Push and hold SW02 for 5 seconds or more. D804 changes to slow flashing, D805 is turned off and then
various settings are invalidated.
* If an unknown point generated on the way of the operation, push and hold SW01 and SW02 for 5 seconds
or more simultaneously. You can return to the item (1).
Confirmation method of various settings
You can confirm that various settings are validated.
1) Check LED displays are in the initial status. If it are not so, return them to the initial status.
2) Push and hold SW01 for 5 seconds or more. D804 changes to slow flashing.
3) Push SW01 several times and then stop it at the point where LED display (D800 to D804) to be checked. If
the setting became valid, D804 and D805 flash rapidly. (When the setup was invalid, D804 flashes rapidly
and D805 goes off.)
4) Push SW01 and SW02 for 5 seconds or more simultaneously to return LED display to the initial status.

When the existing piping uses Ø19.1 pipe, this function is validated.
In this case, the heating capacity may drop due to outside temp. and
indoor temp. in heating time.
This function validates the control to prevent occurrence of motor
lock by the accumulated snow entered from clearance of the fan
guard or heat exchanger into blast route. Even when the compressor
stops, the outdoor fan is operated with SM56, 80 : W3, SM110, 140 :
W5 when the outside temperature is under 4
°
C.
This function is validated if the max. value of compressor frequency
is required to lower. It lowers the max. frequency in cooling/heating
time. In this case, the max. capacity lowers.
