How to set the aim temperature range?
The target temperature range was consist of two values, the SetPoint (abbr.: SP) and the
Hysteresis, this section is about SP, more details of Hysteresis ref 4.6

• Cool mode: The SP is the lower limit to stop refrigerating
• Heat mode: The SP is the upper limit to stop the heating.

It is very simple to change the set-point value:

• Just press the A or | key to change SP, the step is 0.1°C; hold the key to fast forward.
• It will back to normal status in the 3s if without operation.
• SP was limited by the ED I and EG2;

The hysteresis is editable in the admin interface, please find it from the below content.

• Stop, the lasting time according to the Al2;
• work, the lasting time according to the AO t

Timing Function

• The FO 1 and the F02 was designed to define the working status of this controller (power strip), but not the load;
  • info-0, Then this controller ( not the load ) will always work, meanwhile the FD2 is invalid too, no matter FD2 equalsf or else value.
  • info>0, this unit will work in the FB1 set time, and relax in the F02 set time.
• There is a memory unit to save the configured parameters, but will not record the status of the current program running, which means once the input power to this controller off, and then electric back, it will begin to work likes the 1t time power On.

Error & Alarm
once an alarm occurs, Press any key to stop the buZZer from Screaming; but the error code on the screen will not disappear until all the failures are resolved.
