LED Status Description:

• LED: Flashing,indicate cooling or heating delay;  Lighting,indicate the relay is closed.
• Panel buttons: set (set key) + (up key) - (down key)
• 1, the temperature control point setting method:Under normal operation, press the SET button, then the temperature setpoint value is displayed: Press the " + " or " - " key to increase or decrease the temperature setting. long press " + " or " - " to quickly increase or decrease. Without any keystrokes 5 seconds, will automatically save the setting and return to normal operation.
• 2, the cooling and heating mode selection method: Press the "SET" button for 5 seconds to enter menu display, the screen shows P0, press" + " or " - " can switch P0, P1, P2, P3, P4, P5, main menu is displayed, press again to set to enter the setup change the setting, 10 seconds automatically determine and return to normal working condition.

Setting Table:
    Codes       Code Description         Setting range      Factory setting
    P0          Cooling / Heating            C / H                 C
    P1          Hysteresis Setting            1-15                 2
    P2          Lowest Setting Limit          -50                 -50
    P3          Highest setting Limit         110                 110
    P4          Temperature Correction      -7 -  7 ° c           0

Parameters Description:

• P0 (Cooling, Heating Mode)
• Cooling mode: When the temperature measurement value >/= temperature set point, the relay ON, cooling starts; when the temperature measured value
• Heating mode: When the temperature measured value > temperature set point, the heating relay ON, heating starts. when the temperature measurements< /= Temperature set point + hysteresis, the relay OFF, heating closed;
  

• P1 (Hysteresis Setting)
• Cooling Mode: When the temperature measurement value >/= set value, the relay ON, refrigeration starts; when the temperature measured value < set value - hysteresis value, the relay OFF, cooling closed. for example,when the setting is 20 °c,the environment is 30 °c, the hysteresis setting is 2 °c, after powered,relay OFF,cooling starts, when cooling to 17.9 °c, relay OFF,cooling closed, because the cooler has been closed, the temperature began to rise, when rise up to the set value 20 °c, the relay OFF ,the cooler to start again, so repeated cycle control temperature not higher than 20 °c.
• Heating Mode: When the temperature measurement value set value + hysteresis value, the relay OFF, the heater closed. for example setting is 30 °c, the environment is 20 °c, the hysteresis setting is 2 °c,  after powered, relay OFF, heating starts, when heated to 32.1 °c, the relay OFF, the heater colsed, because the heater has been colsed, the temperature begins to drop,drop to the set value dropped 30 °c, the relay closes and the heater to start again, so repeated cycle control temperature not lower than 30 °c

• P2 (Lowest Temperature Setting Limit):
• Defines the lowest temperature control thermostat set point setting range.
• For example: the temperature set point is set to -10°c, then the Minimum can only be set to -10°c, if want to expand the scope of the temperature set-point ,it needs to adjust the upper and lower limit settings.

• P3 (Highest Temperature Setting Limit):
• Defining a temperature control set point of the highest temperature setting range.
• For example: the temperature set point is set to 60°c,then the Maximum can only be  set to 60°c, if want to expand the scope of the temperature set-point, it needs to adjust the upper and lower limit settings.

• P4 (Temperature Correction)
• when the measured temperature and the standard temperature have deviation, can use this feature, the temperature after correction = the temperature before correction + correction value.

• P5 (Delay Start Time, Unit: Minutes):
• Cooling mode: the first powered, if the current temperature >/= the set value, the cooler does not immediately start cooling, it needs to run the set delay time to start.
• Heating mode: the first powered, if the current temperature
• If refrigeration or heater adjacent downtime between two starts greater than the delay start time setting, cooler starts immediately;
• If refrigeration or heater adjacent downtime between two starts less than the delay start time setting, it needs to run through the delay start setting time,then the cooler to starts. delay time start calculation from the downtime.
