Content of check mode 1
By pressing “” consecutively, the following indications will be displayed.
Indication of temperature, etc.
Category code indication
Step
No.
Temperature indication
1 Indoor unit temperature setting (°C).
b1 22
2 Indoor unit air inlet temperature (°C).
b2 20
3 Indoor unit discharge air temperature (°C).
b3 55
4 Indoor unit heat exchanger liquid piping temperature (°C).
b4 20
5
Remote sensor temperature (°C).
- This is only displayed when connected to a remote sensor.
The display normally shows “--”.
The RPK series cannot connect to a remote sensor. The indication is therefore “--”.
b5 25
6 Outdoor unit ambient temperature (°C). b6 10
7 Indoor unit heat exchanger refrigerant gas piping temperature (°C).
b7 25
8 Outdoor unit evaporating temperature during heating (°C).
b8 02
9
Control information.
- Displays internal remote control information.
For the SET-FREE unit, this indication shows the number of compressors running.
b9 --
10
Discharge gas refrigerant temperature in top of compressor chamber (°C).
