1) Common Display Data
Common display data will be indicated in all display pages.
a. Figure means CCM is in network control with PC or Gateway.
b. Figure means CCM is in communication connection with Function Module.
c. Figure means CCM is in communication connection with Message Remote Control
Module.
d. Figure means CCM is in communication connection with Telephone Remote Control
Module.
e. If CCM is in normal communication with NIM, then (Blank),
●
, will be displayed in
dynamic circulation. Otherwise, no any display.
f. Lock Symbol means the CCM is in Lock state or the buttons are in Lock state. ON means
the buttons are in Lock state or both CCM and Buttons are in Lock state, and 0.5 second flash
means the CCM is in Lock state.
g. When setting page layout, if the selected air-conditioner is in Remote Controller Lock state
(in case that several air-conditioners are in operation, if only one is in Remote Controller Lock
state, then that means in Lock state.), symbol will display steadily. If in Mode Lock state,
symbol will flash in 0.5Hz. If Remote Controller Lock state and
Mode Lock state exist at the same time, symbol will display steadily.
2) Display Data Treatment
Data Display area adopts 7-segment code, and there are 5 groups of 2-digital 7-segment
display.
a. TEMP. Display
TEMP. Display is applicable to the following: Set Temp. Ts
（
17-30
℃）
, Indoor Return Air
Temp. T1, Evaporator Pipe Temp. T2A, Evaporator Middle Pipe Temp. T2B, Condenser Pipe
Temp. T3. And the allowable data display range is 0
℃
--99
℃
. If higher than 99
℃
, then display
99
℃
. If lower than 0
℃
, then display 0
℃
. What’s more, the real display range also has
relationship with the PCB temperature checking range. If no effective data, then display “-“and
Unit symbol
℃
will be ON.
b. CURRENT Display
CURRENT display is applicable to Compressor Current. The allowable range is 0A-99A. If
no effective data, then display “-“and Unit symbol mp will be ON.
