Remote controller test run setup
Perform usual operations using the remote controller to check for
normal operation. A test run can be executed forcibly by using the
following procedure if the room temperature is too high to turn off
the thermostat.
1. Turn off the power of the air conditioner, and remove the screws
to detach the signal receiving part cover.
2. Set bit 1 of DIP switch S003 on the signal receiving part P.C.
board to ON.
3. Attach the signal receiving part to the ceiling panel by reversing
the procedure of removal, and then turn on the power of the air
conditioner.
4. Push [START/STOP] button on the wireless remote controller,
and select COOL or HEAT with [Mode] button.
(Temperature cannot be controlled during a test run.)
5. All LEDs on the signal receiving part flash during a test run.
6. After the test run has been completed, be sure to set bit 1 of DIP
switch S003 to OFF and confirm that the LEDs do not flash.
7. Clamp the wires properly with the clamper secured together with
the signal receiving part cover.
Note1: Use the forced test run only for test run because it overloads
the air conditioner.
Note2: The remote controller is disabled for approx. 1 minute after
power-on, but this is normal. The signal from the remote
controller is received, but the receive data is discarded.
