Table 9-8-2 Appr oximate resistance v alue of thermo sensor
9-8-2. How to shorten time of restart delay time
(1) Set the operation mode, temperature, and air flow
rate to be applied with the timer short mode.
(2) Push the [CLR] button while keeping [CHK] button
pushed. in this case, the check mode is released,
and the timer short mode is waited.
(The status is kept even if [CHK] and [CLR] buttons
are released.)
(3) Pushing [START/STOP] buttons sends operation
code + timer short code.
(4) The timer short mode is released by only a trans-
mission. Therefore, repeat steps from (2) to
perform the timer short mode again.

5 Press [START/STOP] button once to
start the unit.
• Shorten the time of the
restart delay timer.
• Set the operation mode to COOL.
• Set the fan speed level to AUTO.
• Set the preset temperature much
lower than the room temperature.
(The unit (compressor)
operates continuously in the above
condition.)
6 Connect the motor connector to the
motor and turn on the power supply.
Start the unit in the following
condition.
• Set the operation mode to FAN.
• Set the fan speed level to HIGH.
(The unit (compressor) operates
continuously in the above
condition.)
1. Check whether or not the compres-
sor operates.
2. Check whether or not the OPERA-
TION lamp blinks.
1. The motor does not operate.
(But it is possible to receive the
signal from the remote control.)
2. The motor rotates but vibrates
strongly.
1. The temperature of the indoor heat
exchanger is extremely low.
2. The connection of the heat
exchanger sensor is loose.
(The connector is disconnected.)
(CN01)
3. The heat exchanger sensor and
the P.C. board are defective.
(Refer to Table 9-8-2.)
4. The main P.C. board is defective.
1. The indoor fan motor is defective.
(Protected operation of P.C. board)
2. The connection of the motor
connector is loose.
3. The P.C. board is defective.
