3.3 Operating Instruction

ET724 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:

3.3.1 Buttons

PAR:parameter button, confirm button. 
Press once and release the button, shift dispaly parameter name and parameter value;

 At parameter name display: increasing parameter No.; At parameter value display: increasing parameter revision.

 At parameter name display: reducing parameter No.; At parameter value display: reducing parameter revision.


3.3.2 Operating Instruction

(1) Operating Mode:

The mode is normal working mode. 3 digits LED display measured temperature and set temperature in turn. Six LED meanings:

PV lamp on: the digital window displays measured temperature;

SV lamp on: the digital window displays set temperature; at cooling mode, it shows cooling start temperature; at heating mode, it shows heating set temperature;

Col lamp on: the current output is cooling; flashing means manual preparation mode; 

Heat lamp on: the current output is heating; flashing means manual preparation mode;

TEC alarm on: TEC failure, fan failure, or temperature sensor failure;

Temp alarm on: measured temperature is higher than set upper limit or lower than set lower limit.

At operating mode, a long press on PAR to shift to parameter name P00 display; press  to select parameter no. for observation or revision.

(2)Parameter Mode (except P00):

At this mode, one can observe or revise the revisable parameters. Refer to 3.3.3 parameter instruction.

At parameter mode: one can manually shift parameter no.(Pnn) or parameter value display (shift with PAR button).

(2) Parameter Mode:

At this mode, one can observe or revise the revisable parameters. Refer to 3.3.3 parameter instruction.

At parameter mode: one can manually shift parameter no.(Pn) or parameter value display (shift with PgUp button).

Remark 1:
DI2 corresponding with the high bit; DI1 corresponding with the low bit.

Remark 2:
Eight alarm codes:
D0 ---- system alarm;
D1 ---- temperature alarm;
D2 ---- temperature sensor fault;
D3 ---- TEC alarm(over current or under current);
D4 ---- inside fan fault(either of the two fans);
D5 ---- outside fan fault(either of the two fans);
D6 ---- DI1 alarm;
D7 ---- DI2 alarm.

When any of the alarm from D2 to D7 occurs, D0 will be 1. For example, the alarm code 21 means D5 is 1, D0 is 1, that is outside fan alarm.
