XH W1209 12V Digital Temperature Controller Module W/ Display and NTC Temp Sensor

The XH W1209 12V Digital Temperature Controller Module with Display and NTC Temp Sensor is a versatile and cost-effective thermostat controller, featuring a 7-segment display and a 3-switch keypad for easy temperature and parameter settings. Equipped with an NTC thermistor temperature sensor, it offers high accuracy of 0.1°C.

This module intelligently controls power to electrical devices based on temperature readings from the NTC sensor. The current temperature is displayed in degrees Celsius on the 3-digit seven-segment display, while the relay state is indicated by an onboard LED.

Here’s a breakdown of its functionality:

1. Displaying the Current Temperature:
The thermostat defaults to displaying the current temperature in °C. After approximately 5 seconds of inactivity, it returns to this default display.

2. Setting the Trigger Temperature:
Press the ‘SET’ button to set the trigger temperature. The seven-segment display will flash, allowing you to adjust the temperature in 0.1°C increments using the ‘+’ and ‘-‘ buttons. After approximately 2 seconds of inactivity, the trigger temperature is stored, and the display returns to the current temperature.

3. Setting Parameters:
Long press the ‘SET’ button for at least 5 seconds to enter parameter setting mode. Press the ‘+’ or ‘-‘ buttons to cycle through parameters (P0 to P6). Press the ‘SET’ button again to change the value of the selected parameter using the ‘+’ and ‘-‘ buttons. After setting a parameter, press the ‘SET’ button to exit that option. After approximately 5 seconds of inactivity, the thermostat exits parameter settings and returns to the default temperature display.

4. Parameter Details:
– P0: Cooling (C) or Heating (H) mode
– P1: Hysteresis (change in temperature before relay state change)
– P2: Upper limit of trigger temperature
– P3: Lower limit of trigger temperature
– P4: Temperature offset correction
– P5: Trigger delay (up to 10 minutes)
– P6: High-temperature alarm setting

With its user-friendly interface and versatile functionality, the XH W1209 Digital Temperature Controller Module is an essential tool for temperature control in various applications.
