3.1.2 Protection Time - PT (Cooling Mode Only)
Frequent start/stop may influence or even shorten the service life of your appliance; we
suggest you to set the parameter PT (Protection Time, i.e. cooling start delay time), to protect
your appliance. Please set it according to your requirements.
Example: When PT is set to 3 minutes, PV (Current Value) > Csp (Cooling start point), the
controller will enter cooling mode if either condition below is satisfied:
The controller is powered on for more than 3 minutes;
●
The interval between two adjacent cooling modes is more than 3 minutes.
●
3.1.3 High Alarm Limit - AH
When PV (Current Value) ≥ AH (High Alarm Limit), high temperature alarm will be triggered,
the LCD displays error code "EAH", the icon
to mute the buzzer, but the error code will remain until PV < AH.
3.1.4 Low Alarm Limit - AL
When PV (Current Value) ≤ AL (Low Alarm Limit), low temperature alarm will be triggered, the
LCD displays error code "EAL", the icon
mute the buzzer, but the error code will remain until PV > AL.
Note: The controller will work normally during AH or AL alarms.
3.1.5 Temperature Calibration - CA
When PV (Current Value) deviates from the standard or actual temperature, please use the
parameter CA to correct it. The calibration value could be positive, 0 or negative and PV
(calibrated) = PV (before calibration) + CA (temperature calibration).
3.1.6 Celsius/Fahrenheit - CF
The controller supports Celsius or Fahrenheit display. The US version default unit is in Fahren-
heit, the UK/EU version default is in Celsius. If the default is di erent from your preferred
unit, please modify the parameter CF as shown in
and buzzer beeps promptly. Press any button
and buzzer beeps promptly. Press any button to
