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 and buzzer beeps promptly. Press any button
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 and buzzer beeps promptly. Press any button to
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 different from your preferred
unit, please modify the parameter CF as shown in
2.4 Parameter Settings.
