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.
