Description

W1209WK

Input Voltage: DC 12V

Red + Blue Dual Display

Celsius / Fahrenheit Dual Mode

Temperature Measurement Range: -50 Celsius~-110 Celsius

Cable length:30CM

Indicator light, digital tube status description:

Indicator light: Off means the relay is off, steady light means the relay is closed

Digital tube: The above shows that LL is the sensor open circuit; the display HH is out of the measurement range. The temperature controller will forcibly open the relay; display - for high temperature protection.

【Instructions】

Key Description: The SET button is also the setting button; the C/F button is the Fahrenheit and Celsius conversion buttons.

Press the SET button while the actual temperature is displayed, the lower setting number flashes (the lower setting temperature flashes), then SET(+) C/F(-) to set the desired setting temperature. 3 seconds automatically confirms the return. At this time, the controller automatically performs relay on/off according to the set temperature. The rated output of the thermostat is 12V20A relay, which satisfies all kinds of high power. Please make sure the line is correct.

Under normal working conditions, short press the C/F (-) button to switch between Fahrenheit and Celsius.

In normal working environment, press and hold the SET button 5S to enter the main menu settings, press SET (+), C / F (-), to select P1-P8 mode, after confirming the mode, press and hold SET (+) , C / F (-) enter the mode setting parameters. At this time, the number below is flashing, and then the SET (+), C / F (-) button to adjust the size of the parameter, automatically save and exit after 3S. The setup is complete.

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.
