Serial signal transmission error protection
(i)
Purpose:
Prevents malfunction resulting from error on the indoor
↔
outdoor signals.
(ii)
Detail of operation:
If the compressor is operating and a serial signal cannot be received from the indoor control with
outdoor control having serial signals continuously for 1 minute and 55 seconds, the compressor is
stopped.
After the compressor has been stopped, it will be restarted after the compressor start delay if a serial
signal can be received again from the indoor control.
(RUN light: ON, TIMER light: 6 time flash)
(h)
Sensor disconnection (room temperature, indoor heat exchanger, outdoor heat exchanger, outdoor tempera-
ture, discharge pipe)
(i)
Room temperature sensor
If the temperature detected by the room temperature sensor is –20ºC or lower continuously for 15 seconds or longer while
operation is stopped, an error indication is displayed. (Run light: 2 time flash, Time light: ON)
(ii)
Indoor heat exchanger temperature sensor
If the temperature detected by the indoor heat exchanger temperature sensor is –20ºC or lower continuously for 15 seconds
or longer while operation is stopped, an error indication is displayed.
(Run light : 1 time flash, Timer light : ON)
(iii) Outdoor heat exchanger temperature sensor
If the temperature detected by the outdoor heat exchanger temperature sensor is –64ºC or lower continuously for 15 seconds
or longer while operation is stopped, an error indication is displayed.
(Run light : keep flashing, Timer light : 2 time flash)
(iv) Outdoor air temperature sensor
If the temperature detected by the outdoor air temperature sensor is –64ºC or lower continuously for 15 seconds or longer
while operation is stopped, an error indication is displayed. (Run light : keep flashing, Timer light : 1 time flash)
(v)
Discharge pipe temperature sensor
After the compressor has operated for 9 minutes continuously, if there is a disconnected signal for the discharge pipe tem-
perature sensor detected -64
°
C for 15 seconds, the compressor stops. After a 3-minute delay, it restarts, but if an abnormality
is detected 4 times continuously, the air-conditioner is stopped fully and an error indication is displayed. (Run light : keep
flashing, Timer light : 4 time flash)
