Usage Instructions

1. Press the button to select your desired temperature (hold the button to adjust quickly). The display will show the set temperature.
2. Press "SET" to confirm your selection. The controller will automatically manage the relay to achieve the desired temperature.
3. The 20A relay output is designed to accommodate various high-power loads. Connect the appropriate control circuit and supply power to the thermostat. The display will show the current ambient temperature.
4. Indicator light: Blinks to indicate the start delay of cooling or heating. A steady light means the relay is closed.
5. Digital control:
   • "LL" display indicates the sensor is open. Please ensure proper sensor connection.
   • "HH" display means the temperature is outside the measurable range, forcing a relay disconnect.
   • High temperature alarm is also displayed for temperatures beyond safe limits.

Package Includes

• 1 x XH-W1209 Temperature Controller with case
