5.3 Cool and Heat Mode
5.3.1 Cool Mode
In cool mode, when the setting temp<=(the current temp-DV), the load will be turned on, the
icon is displayed; and when the setting temp>=the current temp, the load will be turned off, the
icon is displayed. The icon appears when the controller is in cool mode.
5.3.2 Heat Mode
In heat mode, when the setting temp>=(the current temp+DV), the load will be turned on, the
icon is displayed; and when the setting temp<=the current temp, the load will be turned off,
the icon is displayed. The icon appears when the controller is in heat mode.
5.4 Backlight
The screen will lit on for 8 seconds when you press any button.
5.5 Alarm High/Low Temperature Limit Setting(AH.AL)
When measured temperature
≥
AH, high temperature limit alarm, screen appears AH alternate
with current temperature, until the temperature <AH，screen returns to normal display.
When measured temperature
≤
AL, low temperature limit alarm, screen appears AL alternate
with current temperature, until the temperature >AL，screen returns to normal display.
5.6 Temperature Calibration(tC)
When the measured temperature deviates from the standard temperature, the temperature
calibration function can be used to make the measured value of the instrument consistent with
the standard value. The calibrated temperature=the measured temperature + the calibration
value.
5.7 Compressor Delay Time(Cd)
In the cooling mode, when the power is turned on for the first time, the current temperature
≥
(the setting temp + DV), it will not start cooling immediately, but waiting for a delay time(Cd).
When two adjacent of cooling starting intervals are greater than the delay time, it will
immediately start cooling; When two adjacent of cooling starting intervals are less than the delay
time, it needs to operate the remaining delay time to start the cooling.
Delay time will start counting from the cooling output off.
5.8 Fahrenheit or Celsius Settings(CF)
The users can set display unit to Fahrenheit or Celsius according to their habits. The default
temperature is Fahrenheit. If you need to display the unit in Celsius, then set the CF to C. Please
note that when the CF changes state, all setting values are restored to the default setting.
