Description

The XH-W1209 12V Digital Temperature Controller Module with Display and NTC Waterproof Temperature Sensor is a cost-effective, feature-rich thermostat controller designed for a variety of applications. Its user-friendly interface, coupled with precise temperature sensing capabilities, makes it a versatile choice for projects ranging from temperature measurement to controlling electrical devices based on temperature thresholds.

Features:

  • Temperature Sensing Precision: The module utilizes an NTC thermistor temperature sensor with an impressive accuracy of 0.1°C, ensuring precise temperature measurements for your projects.
  • User-Friendly Interface: Equipped with a 3-switch keypad and a 3-digit seven-segment display, this module allows easy configuration of parameters without the need for programming skills.
  • Configurable Trigger Temperature: Set the trigger temperature effortlessly by pressing the 'SET' button and adjusting it using the '+' and '-' buttons in 0.1°C increments. The configured trigger temperature is stored automatically.
  • Parameter Configuration: Long-press the 'SET' button to access parameter configuration. Cycle through parameters (P0 to P6) using the '+/-' buttons. Customize settings such as heating or cooling mode (P0), hysteresis (P1), upper and lower temperature limits (P2 and P3), temperature offset correction (P4), trigger delay (P5), and high-temperature alarm (P6).
  • Powerful Relay Output: The onboard relay can handle up to 240V AC at 5A or 14V DC at 10A, providing robust switching capabilities for a wide range of electrical devices.

 

Specifications:

  • Temperature: -10 ~ 60°C
  • Humidity: 20-85%
  • Static Current: <=35mA
  • Current: <=65mA

 

How to Set Parameters on the XH-W1209 12V Digital Temperature Controller Module:

  1. Accessing Parameter Settings:

    • Long press the 'SET' button for at least 5 seconds.
    • The seven-segment display will show 'P0,' indicating parameter selection.
    • Press the '+/-' buttons to cycle through parameters P0 to P6.
  2. Setting the Cooling or Heating Parameter (P0):

    • Parameter P0 has two settings: C and H.
    • Set to C (default) if you want the relay to energize when the temperature is reached, ideal for air-conditioning systems.
    • Set to H if you want the relay to de-energize when the temperature is reached, suitable for controlling a heating device.
  3. Setting the Hysteresis Parameter (P1):

    • Adjusts how much change in temperature must occur before the relay changes state.
    • Default value is 2°C.
    • Example: If trigger temperature is set to 25°C, with a hysteresis of 2°C, the relay won't de-energize until the temperature falls below 23°C.
  4. Setting the Upper Limit of the Thermostat (P2):

    • Limits the maximum trigger temperature that can be set.
    • Acts as a safety feature to prevent accidentally setting an excessively high trigger temperature.
    • Default value is 110°C.
  5. Setting the Lower Limit of the Thermostat (P3):

    • Limits the minimum trigger temperature that can be set.
    • Acts as a safety feature to prevent accidentally setting an excessively low trigger temperature.
    • Default value is -39°C.
  6. Setting Temperature Offset Correction (P4):

    • Corrects differences between displayed and actual temperature.
    • Useful when the temperature probe is on a long cable.
    • Default value is 0.
  7. Setting the Trigger Delay Parameter (P5):

    • Allows for delaying the relay switching when the trigger temperature is reached.
    • Can be set in one-minute increments up to a maximum of 10 minutes.
    • Default value is 0 minutes.
  8. Setting the High-Temperature Alarm (P6):

    • If a value is set, the relay will switch off when the temperature reaches this setting.
    • The seven-segment display will show '—' to indicate an alarm condition.
    • The relay won't re-energize until the temperature falls below this value.
    • Default setting is OFF.
  9. Settings Chart:

    • Long press the 'SET' button to activate the menu.
    • Set the values as mentioned in the bracket for each parameter (P0 to P6).
  10. Resetting Values:

    • Long press the '+/-' buttons to reset all values to their default settings.
