The W1209 thermostat module features a temperature sensor, keys, LED display, and relay, making it an affordable and good quality thermostat controller. NTC temperature sensor allows intelligent control based on temperature, with an inbuilt micro-controller requiring minimal programming knowledge.

The module includes three switches for configuring parameters such as ON and OFF trigger temperatures. The relay operates at voltages up to 240V AC at 5A or 14V DC at 10A. Temperature is displayed in degrees Celsius on the 7-segment display, with the relay state indicated by the LED on the module.

Settings Chart:

• P0 Heat C/H C
• P1 Backlash Set 0.1-15 2
• P2 Upper Limit 110 110
• P3 Lower Limit -50 -50
• P4 Correction -7.0 ~ 7.0 0
• P5 Delay Start Time 0-10 mins 0
• P6 High-Temperature Alarm: 0-110 OFF

Working:
Current temperature is displayed in degrees Celsius, with inactivity leading to the default temperature display. Trigger temperature and parameter settings can be configured using buttons on the module.

Parameters Setting:

Long-press the “SET” button to access the menu and change parameters such as heating mode, hysteresis, upper and lower temperature limits, and delay start time. Each parameter can be set using the +/- buttons, with a reset option available by long-pressing the buttons.

Alarm Parameter P6:

When the temperature reaches the specified value, the relay switches off. An alarm condition is indicated on the display, and the relay remains off until the temperature falls below the set value.
