    ◆Cooling, heating function:
     Cooling Mode: When the measured temperature is higher than or equal to the set value + hysteresis, the relay picks up to start the output; When the measured temperature below the set value, the relay off and close the output.
     Heating mode: When the measured temperature is higher than or equal to the set value, the relay off, turn off the output; When the measured temperature below the set value - hysteresis, the relay picks up to start the output.

     

    Example for Setting: If it is set to heating mode, set the temperature to 25 degrees, hysteresis is set to 5, then when the measured temperature is higher than or equal to 25 degrees, the relay is off, close the output. When the temperature is below 20 degrees, pick up the relay again, to start the output. 
    Example for Setting: If it is set to cooling mode, set the temperature to 25 degrees, hysteresis is set to 5, then when the measured temperature is below 25 degrees, the relay is off, close the output. When the temperature is higher than or equal to 30 degrees, pick up the relay again, to start the output.

    ◆ Cooling, heating mode setting:
    Press “SET1” and “UP”key and hold on for 3 seconds  to enter the menu display, the screen appears "HC" code, press the "SET1" key to display the working mode, press the "UP" or "DOWN" to adjust the display, C means cooling mode; H means heating mode.

    ◆ Hysteresis function:
     Hysteresis setting limits the maximum interval between the opening and stopping.

    ◆ Hysteresis settings:
     Press “SET1” and “UP”key and hold on for 3 seconds  to enter the menu display, with "UP" or "DOWN" key adjusted to the screen, appearing "D" code, press the "SET1" key to display the hysteresis set value, press "UP "Or "DOWN" key to adjust the parameters.

    ◆ Temperature calibration function:
     When there is deviation between the measuring temperature and standard  temperature, use the temperature calibration function, make the machine  measurements value consistent with the standard temperature, the after calibration temperature= the before calibration temperature + calibration value (calibration value can be positive number, negative number, and 0) .

    ◆ Temperature calibration settings:
     Press “SET1” and “UP”key and hold on for 3 seconds  to enter the menu display, with "UP" or "DOWN" key adjusted to the screen, appearing "CA" code, press the "SET1" key to display the temperature calibration settings, press "UP "Or"DOWN"key to adjust the parameters.

    For example: When we measure the probe temperature was 25 degrees, it displays 25 degrees as the CA is 0, it displays 26 degrees as the CA is 1, it displays 24 degrees as the CA is -1. This function is generally applied when the probe can not measure directly the measured object. For example, we place the probe at the outside of a cup to measure its water temperature, we need to adjust the CA parameters because of the heat loss of the cup, so that the display temperature can be in accordance with the one of the cup.

     

    ◆ Delay Protection Function:
     In the cooling mode, the first power on, when the measured value above the set value + hysteresis value, the machine will not immediately start cooling, it needs to set the delay time, then the machine can run to start cooling; once the interval between two cooling is larger than the delay time, the machine immediately starts cooling, once the interval between two cooling is less than the delay time, the machine must run the remaining delay time to start cooling. The delay time is started to calculate from stopping the machine. The delay time of heating mode is as same as the cooling mode.
     Note: It is recommended that only the device that use compressor cooling can use the delay start function, the user who don't need delay start function please set this parameter to 0.

    ◆ Delay Protection Setting:
    Press “SET1” and “UP”key and hold on for 3 seconds  to enter the menu display, with "UP" or "DOWN" key adjusted to the screen, appearing "PT" code, press the "SET1" key to display the delay setting value, then press the "UP "or "DOWN"key to adjust the parameters.

    ◆ Upper and lower limit functions:
     The setting of HS and LS limit the set range of control temperature point , for example: HS is set to +15, LS is set to -10, the control temperature can only be adjusted between -10 and +15, when the control temperature to -10 then press "DOWN" key, the display will remain on the status of -10 and not decrease; when the control temperature to +15 then press "UP" key, the display will on the status of 15 and not increase. If the set point outside this range, it needs to firstly change the value of HS and LS, then it can be achieved.

    ◆Upper and lower limit settings:
     Press “SET1” and “UP”key and hold on for 3 seconds  to enter the menu display, with "UP" or "DOWN" key adjusted to the screen, appearing "HS" or "LS" code, press the "SET" key to display the upper or lower limit set value, Then press "UP" or "DOWN" key to adjust the parameters. HS means upper limit. LS means lower limit.
