Indoor unit A evaporator outlet
temperature (T2BA)
If the temperature is lower than -9°C, the digital display
shows “-9.” If the temperature is higher than 70°C, the digital
display shows “70.” If the indoor unit is not connected, the
digital display shows: “--”

20
Indoor unit D evaporator outlet
temperature (T2BD)
21
Indoor unit E evaporator outlet
temperature (T2BE)
22
Indoor unit A room
temperature (T1A)
If the temperature is lower than 0°C, the digital display shows
“0.” If the temperature is higher than 70°C, the digital display
shows “70.” If the indoor unit is not connected, the digital
display shows: “--”

Compressor discharge
temperature (TP)
The display value is between 30°–129°C. If the temperature
is lower than 30°C, the digital display shows “30.” If the
temperature is higher than 99°C, the digital display shows
single and double digits. For example, if the digital display
shows “0.5”, the compressor discharge temperature is 105°C.
35 AD value of current The display value is a hex number.
For example, the digital display tube shows “Cd”, it means AD
value is 205.
36 AD value of voltage
