How simple would it be to automatically turn on your fan based on temperature changes? All you need to do is set a trigger temperature for when the fan should activate or deactivate. The W1209 module, which is highly functional and cost-effective, can help you create this impressive home automation!

The W1209 thermostat module includes a temperature sensor, buttons, an LED display, and a relay, requiring a DC 12V power supply. It is an affordable and reliable thermostat controller. Thermostats are devices that monitor the temperature of a system to maintain it at a desired set point or close to it. The NTC temperature sensor enables the module to intelligently control various electrical devices based on temperature. An NTC thermistor has a negative temperature coefficient, meaning its resistance decreases as the temperature rises.

The W1209 features an embedded microcontroller, so minimal programming knowledge is needed. The module includes three switches for configuring parameters, including the ON and OFF trigger temperatures. The relay can handle voltages up to a maximum of 240V AC at 5A or 14V DC at 10A. The temperature is displayed in degrees Celsius on a 7-segment display, and the relay's state is indicated by an LED on the W1209 module.

W1209 Module SPECIFICATIONS:-

  • Temperature Control Range: -50 ~ 110 C
  • Resolution at -9.9 to 99.9: 0.1 C
  • Resolution at all other temperatures: 1 C
  • Measurement Accuracy: 0.1 C
  • Control Accuracy: 0.1 C
  • Refresh Rate: 0.5 Seconds
  • Input Power (DC): 12V
  • Measuring Inputs: NTC (10K 0.5%)
  • Waterproof Sensor: 0.5M
  • Output: 1 Channel Relay Output,
  • Capacity: 10A

Power Consumption:-

  • Static Current: <=35mA
  • Current: <=65mA

Environmental Requirements:-

  • Temperature: -10 ~ 60 C
  • Humidity: 20-85%

Dimensions:-

  • 48mm x 40mm x 14mm


Settings Chart:-

  • Long press the “SET” button to activate the menu.
  • Code Description Range Default Value
  • 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
  • Long pressing +- will reset all values to their default

Working:-

Current temperature will be displayed on the module in degree Celsius by default. When switched to a different mode, inactivity for approximately 5 seconds would lead to restoring the value of the module to the default temperature display.


Setting Modes:-

Trigger Temperature:Press “SET” button on the module and current temperature will be displayed on the screen. Using “+” and “-“ button, one can set the temperature in 0.1 degrees (Celsius) increments. No activity for 2 seconds will result in setting and storing the trigger temperature and then the screen will display the current temperature.

Parameters Setting:-

Pressing the “SET” button for a minimum of 5 seconds will lead to the setting of the parameter present in the module. The seven segment display will start with the display of first parameter “P0”. Pressing ‘ + ’ or ‘ - ‘ buttons will help to go to parameters (P0-P6). Pressing “SET” button midst the parameters will let you change the value for that parameter. After setting the required parameter, press set button to exit that option. If no button is pressed for 5 seconds the thermostat will exit the parameter option and will return back to the default temperature.

Heating Parameter P0: P0 has two settings, C and H. The default setting C can be used to connect to an air-conditioner as the relay energizes when the temperature is reached. Setting H leads to de-energizing the relay when the required temperature is detected. It can be used to control any heating device.

Hysteresis Parameter P1: This parameter sets the range of change in temperature that must occur before relay will change state.

Parameter P2 (Upper Limit Temperature): P2 limits the maximum trigger temperature that can be set. It acts as a safety feature that stops the user to set an extremely high trigger temperature.

Parameter P3 (Lower Limit Temperature): P3 limits the minimum trigger temperature that can be set. It also acts as a safety feature that stops the user to set a low triggering temperature.

Offset Correction Parameter P4: Changes can be made if there is a difference between the displayed temperature and actual temperature reading with this parameter.

Delay Parameter P5: Delay in the switching of the relay when the trigger temperature has reached, can be set by the help of delay parameter P5. It can be set in one-minute increments up to a maximum of 10 minutes.

Alarm Parameter P6: This parameter causes the relay to switch off when the temperature reaches its settings. The display will show ‘ --- ‘ to indicate an alarm condition. The relay will not re-energize until the temperature falls below this value.
