Package Include: 1PC x  W3230 AC 110-220V/DC 12V Digital Thermostat Temperature Controller Regulator Heating Cooling Control Thermostat Instruments -55-120 Degree Instructions: Connect the power supply and equment to supply power to the controller. At this time, it is displayed as measuring temperature. Pre SET once, the display temperature will flash, pre +- to set the desired temperature (pre +- to quickly raise and lower) After finishing, pre SET to confirm the return. At this time, the controller automatically performs relay on/off according to the setting! The output of the thermostat is a 20A relay, which satisfies various high-power loads. When the control circuit is connected, the thermostat can be powered. At this time, the display shows the ambient temperature. Indicator light, digital tube status descrtion Indicator light: Blinking indicates cooling or heating start delay, always on indicates that the relay is closed Digital tube: Display LL is the sensor open circuit, please follow the instructions to connect the sensor; display HH is out of the measurement range, the thermostat will forcibly open the relay; display --- for high temperature alarm Parameter function descrtion Pre and hold SET for 5 seconds to enter the main menu settings, pre +- to switch P0...P6, long pre SET or 10 seconds without on action, the controller automatically confirms the return. P0 cooling and heating mode Pre and hold SET for 5 seconds to display P0, pre SET once to set the working mode, pre +- to switch [H is heating mode] [C is cooling mode] Pre SET once to return, long pre SET or 10 seconds without on action controller automatically confirm carry out. In the cooling mode: when the temperature measurement value ≥ the temperature set point, the refrigeration relay is closed and the refrigerator is started; when the temperature measurement value ≤ temperature set point - the return difference, the refrigeration relay is turned off and the refrigerator is turned off. In the heating mode: when the temperature measurement value ≤ temperature set point, the heating relay pulls in and the heater starts; when the temperature measurement value ≥ temperature set point + hysteresis, the heating relay is turned off and the heater is turned off. P1 hysteresis setting Pre and hold SET for 5 seconds to display P0, pre +- to switch to P1, pre SET once to return the difference, pre +- to set the difference to 0.1-15, pre SET once after completion, long pre SET or 10 seconds without on The motion controller automatically confirms the completion. In the cooling mode: when the temperature measurement value ≥ the set value, the relay is closed, the refrigerator starts; when the temperature measurement value ≤ the set value - the difference value, the relay is turned off and the refrigerator is turned off. For example, if the environment is 30 °C, the set value is 25 °C, and the hysteresis is set to 2 °C. After the power is turned on, the relay closes the refrigerator to start. When the cooling reaches 23 °C, the relay turns off the refrigerator and the refrigerator is turned off. The open temperature starts to rise. When it rises to the set value of 25 °C, the relay closes the refrigerator again, so the repeated cycle control temperature is not higher than 25 °C. In the heating mode: when the temperature measurement value ≤ the set value, the relay pulls in and the heater starts; when the temperature measurement value ≥ the set value + the difference value, the relay is turned off and the heater is turned off. For example, if the environment is 10 °C, the set value is 25 °C, and the hysteresis is set to 2 °C. After the power is turned on, the relay closes the heater to start. When it is heated to 27 °C, the relay turns off the heater and the heater is turned off. The on temperature begins to decrease. When it drops to the set value of 25 °C, the relay closes the heater to start again, so the repeated cycle control temperature is not lower than 25 °C. P2 maximum temperature setting upper limit In order to avoid the danger of setting the temperature too high due to the misoperation of others, the thermostat has the highest setting upper limit function, which limits the setting range of the highest temperature set point controlled by the thermostat. Pre and hold SET for 5 seconds to display P0, pre +- to switch to P2, pre SET once to set the upper limit, pre +- to set the highest settable temperature, the maximum value is 110, pre SET once after completion, pre SET or 10 The second on is not preed and the controller automatically confirms the completion. For example: set to 60 temperature set point can only be set to 60 ° C. If the temperature set point is to be expanded, the upper limit set value needs to be adjusted first. P3 lowest temperature setting lower limit In order to avoid the ice blockage caused by the misoperation of others, the temperature controller has the lowest setting upper and lower limit functions, which limits the setting range of the lowest temperature set point controlled by the thermostat. Pre and hold SET for 5 seconds to display P0, pre +- to switch to P3, pre SET once to set the minimum lower limit, pre +- to set the lowest settable temperature, the lowest value is -50, pre SET once after completion, pre SET or The controller automatically confirms completion without a on action for 10 seconds. For example: set to 2 temperature set point can only be set to 2 °C minimum. If the temperature set point is to be expanded lower, the lower limit set value needs to be adjusted first. P4 temperature correction When the measured temperature is deviated from the standard temperature or due to special needs of the user's hardware, this function can be used for correction. The corrected temperature = temperature before correction + correction value The valid range is -7.0~7.0. Pre and hold SET for 5 seconds to display P0, pre +- to switch to P4, pre SET once to correct, pre +- to set the correction value, pre SET once after completion, long pre SET or 10 seconds without on action controller automatically confirms completion . For example, the normal display is 25 degrees; when the temperature is corrected to 0, it displays 25 degrees; when the temperature is corrected to 1.5, it shows 26.5 degrees; when the temperature is corrected to -1.5, it shows 23.5. P5 delay start time (unit: minute) When the refrigerator or heater is working with a delay, the delay function can be turned on to protect the life of the device. Pre and hold SET for 5 seconds to display P0, pre +- to switch to P5, pre SET once to set the delay start time unit is minute, pre +- to set 0-10 minutes, pre SET to return after completion, long pre SET or 10 seconds No on action controller automatically confirms completion In the cooling mode: the first time the power is turned on, if the current temperature ≥ the set value, the refrigerator will not start the cooling immediately, and it needs to run after the set delay time. In the heating mode: the first time the power is turned on, if the current temperature ≤ the set value, the heater will not start heating immediately, and it needs to run after the set delay time. The chiller starts immediately when the downtime between the two starts of the chiller or heater is greater than the set value of the delay start time. When the stop interval between the two starts of the refrigerator or heater is le than the set value of the delay start time, the device can start after restarting the set delay time of the set after the run. The delay time is calculated from the moment of shutdown. For example, the setting delay is 5 minutes in the cooling state, the cooling device starts to delay after the power is turned on, and the refrigerator is turned on after 5 minutes. When the required temperature is reached, the refrigerator stops, and the timing starts, when the next cooling start timing is completed. Work, unfinished timing must wait for the end of the timer to work, the LED indicator flashes during the delay. When the delay start is set to 0, it is equal to the off delay function. How to save settings If you want to save the set data, set P7 to ON when the temperature is set and the power is off. In this case, the last setting will be retained when the power is turned off. Reset Due to some human reasons, the internal setting of the thermostat is confusing. It takes a lot of time to set the time. In this case, you can use this function to restore the factory settings. In the off state, pre and hold the + and - ons simultaneously. , then power on, all the above parameters are restored to the factory settings.
