Indoor unit A evaporator outlet
temperature (T2BA)
If the temperature is lower than -9
o
C, the digital display
shows “-9.” If the temperature is higher than 70
o
C, the digital
display shows “70.” If the indoor unit is not connected, the
digital display shows: “--”
18
Indoor unit B evaporator outlet
temperature (T2BB)
19
Indoor unit C evaporator outlet
temperature (T2BC)
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
o
C, the digital display shows
“0.” If the temperature is higher than 70
o
C, the digital display
shows “70.” If the indoor unit is not connected, the digital
display shows: “--”

24
Indoor unit C room
temperature (T1C)
25
Indoor unit D room
temperature (T1D)
26
Indoor unit E room
temperature (T1E)
27
Indoor unit A evaporator
temperature (T2A)
If the temperature is lower than -9
o
C, the digital display shows
“-9.” If the temperature is higher than 70
o
C, the digital display
shows “70.” If the indoor unit is not connected, the digital

Indoor unit D evaporator
temperature (T2D)
31
Indoor unit E evaporator
temperature (T2E)
32
Condenser pipe temperature
(T3)
33
Outdoor ambient temperature
(T4)
34
Compressor discharge
temperature (TP)
The display value is between 30–129
o
C. If the temperature
is lower than 30
o
C, the digital display shows “30.” If the
temperature is higher than 99
o
C, the digital display shows
single and double digits. For example, if the digital display
shows “0.5”, the compressor discharge temperature is 105
o
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
