3. the method of use

Connect the power supply and equipment to supply power to the thermostat. At this time, the temperature is displayed. Press the SET button, the display temperature will flash, press +- to set the desired temperature (press +- to quickly raise and lower) After finishing, press SET to confirm the return. At this time, the thermostat automatically performs relay on/off according to the setting!

4. the indicator light and digital tube status description

Indicator light: The yellow indicator light is always on, indicating that the relay is closed.

Digital tube: Display LLL is the sensor open circuit, please follow the instructions to connect the sensor; display HHH is out of the measurement range, the thermostat will force the relay to open

5. parameter function description

Press and hold SET for 5 seconds to enter the main menu settings, press +- to switch P0...P6, long press SET or 5 seconds without key action, the thermostat automatically confirms the return.

P0 cooling and heating mode (factory is cooling mode)

P1 hysteresis setting (factory value 2 ° C)

P2 upper temperature setting upper limit (factory value 110 °C)

P3 lowest temperature setting lower limit (factory value -50 °C)

P4 temperature correction (factory value 0 ° C)

P5 delay time (factory value 0 minutes)

Restore factory settings:In the off state, press and hold the + and - buttons simultaneously, then turn on the power, the digital tube displays 888 and all parameters are restored to the factory defaults.
