  Compressor operation sign 

  Fan motor operation sign 

Electric heating operation sign 

  AUTO RESTART sign. When the system is set at AUTO RESTART mode, if the power supply is cut 

down, when the power comes back again, the system will resume the operation mode before the power is 

cut down. 

Wired controller buzzer closed sign 

  Hint sign of password input. When modifying the factory parameter, the password must be filled in. 

Fan coil simultaneous control sign. The system can be set to start up following the fan coil startup. 

When one of fan coils is started up, the system will be started up too. When all the fan coils stop, and 

after a while, the system will stop automatically. Also the system can be connected to a remote control 

switch. 

Telephone remote control sign. If the wired controller is equipped with a remote control card, it can 

realize the telephone remote control function. 

Time sign. It can display the real time and the auto switch on/off time, also it can display 

the parameter when setting the parameter and querying the parameter. 

Auto switch on/off and clock sign. It is used to set the switch on/off and the real time clock. 

Indication sign, SYS is used to indicate the module of the system (plus A, B, 

C, D, E, F, G, H), COM is used to indicate the communication failure (plus A, B, C, D, E, F, G, H), 

flow is used to indicate the flow failure (plus A, B, C, D, E, F, G, H). 

Indication sign, vent is used to indicate the discharging 

temperature overheat (plus A, B, C, D, E, F, G, H or 9, or 10); over is used to indicate the 

compressor or fan motor overload (plus the corresponding signs).
