8.3 Operating Instruction
ET872 uses user-friendly interfaces, which can be operated easily. All the operations can be realized with four buttons. The following is the control board diagram:
Diagram 4 Control Board Diagram
8.3.1 Buttons
PgDn:page down button, confirm button.
Press once and release the button, page down;
A long press on the button, enter or exit parameter status;
At operating status: can select five display interfaces;
At parameter status: revise, confirm and parameter page down button; a long press on the button to exit parameter status.
▲:increasing parameter revision. Page down button for event query.
▼:decreasing parameter revision. Page up button for event query.
PgUp: page up button; the function is oppose to PgDn operation.
8.3.2 Indicators
When the air conditioner works normally, the Work indicator flashes at 2s frequency, showing it is working normally. When there is screen saver, the indicator can indicate the system is working normally.
When the system has alarm, the Alarm indicator will turn on, showing alarm occurs.
8.3.3 Operating Interfaces
The controller includes three working modes: operating mode, parameter mode, and query mode.
(1) Operating Mode:
The mode is normal working mode. There are five operating interfaces which can be selected. The five interfaces display different content. When they are not selected, the interfaces will automatically shift. Press the button “PgDn” to select next display interface; press the button “PgUp” to select the previous display interface.
Interface 1:
Line 1: temperature and humidity inside the thermostatic box (or area I);
Line 2: temperature and humidity inside communication room (or area II);
Diagram 4 is the first interface (main interface) of this mode.
Interface 2:
Line 1: control status indication. Separated by the sign “/”, the former is box air conditioner status: “OFF” means compressor and heater both stop; “30%-100%” means compressor output percentage; “¤” means heater are working; “♂” means hydrogen exhaust or direct ventilation. The latter is cabinet air conditioner status: “Off” means stop; the first “*” means cabinet air conditioner control; the second “*” or “>” is actual status, means the air conditioner is at cooling status; If it display “>”, it means the air conditioner only blow air.
Line 2: real time, manual/auto status. “Auto” means auto status, “Menu” means manual status.
At manual mode of this interface, press buttons “▲,▼” can manually increase or reduce control output of box air conditioner, and the control output of fan will increase or reduce synchronously.
Interface 3:
Display real rotational speed of inner fan and outer fan.
At manual mode of this interface, press buttons “▲,▼” can manually turn on/off control output of cabinet air conditioner.
Interface 4:
Display temperature of inner coil and outer coil.
At manual mode of this interface, press buttons “▲,▼” can manually turn on/off control output of hydrogen exhaust.
Interface 5:
Circularly display current alarms;
When multiple alarms occur, it will display each alarm information circularly.
(2)Parameter Mode:
At operating status, long press on the button ”PgDn” for around 3 seconds, or press the button ”PgUp” at interface 1, to enter parameter mode.The first entered interface is the main menu interface, see the following diagram.
Press the button “▲”, “▼” to choose corresponding parameter group; Press ”PgDn” to enter corresponding parameter group; Press ”PgUp” to return to operating mode. The parameters selection includes:
(a) Observation Parameter
(b) Control Parameter Revision
(c) Basic Parameter Revision
(d) Manual/Auto Selection
(e) Event Query
(f) Return To Operating Mode
(a)Observation Parameter Group (Apar):
Enter the interface to check some parameters which can’t be checked at operating mode, see “8.3.4 Parameter Instruction”.
At parameter mode: on the left of line 1 is Parameter No. (PAnn); on the right of line 1 is parameter value. Line 2 shows the remark of the parameter.
(b) Control Parameter Group (CPar):
Enter the interface to observe or revise the parameters which can be revised, see “8.3.4 Parameter Instruction”.
At parameter mode: on the left of line 1 is Parameter No. (PCnn), on the right of line 1 is parameter value. Line 2 shows the remark of the parameter.
(c) Basic Parameter Group (BPar):
Enter the interface to observe or revise the parameters which can be revised, see “8.3.4 Parameter Instruction”.
At parameter mode: on the left of line 1 is Parameter No. (PBnn), on the right of line 1 is parameter value. Line 2 shows the remark of the parameter.
(d) Manual Operation Parameter Group (A/M):
Enter the interface to select “Cool”, “Heater”, “Air”, “ToAuto” to conduct manual start and stop operation.
(e) Event Query (Query):
Enter query mode
