Operation Instructions:
1. Power
When the controller is powered on, it begins self testing, with the digital tube displayed and the indicator light fully illuminated. After 3 seconds, the digital tube displays the current temperature and the corresponding indicator is illuminated. That means it operates at the set temperature. The factory default heating setting is 25 ° C, the cooling setting is 5 ° C, and the working state is heating.

2. Indicators  
Yellow indicator light means heating mode. Green indicator light means cooling mode. Red indicator light means the heating or cooling mode is going on. And the red indicator light off means that the current temperature has reached to the requirement.

3. Temperature Setting
- Setting Button: to switch between normal operation and temperature setting
- Up Button: to increase the setting temperature  
- Down Button: to reduce the setting temperature

Working Modes:
- Cooling: When the control temperature ≥ set temperature +1 ℃, switched load power; When the control temperature ≤ set temperature -1 ℃, off load power
- Heating: When the control temperature ≥ set temperature +1 ℃, off load power; When the control temperature ≤ set temperature -1 ℃, switched load power

Fault Protection:
- When the sensor is short-circuited, the digital tube displays [dd], entering into fault operation mode. It will exit fault operation mode immediately after the sensor back to normal;
- When the sensor is open circuit, the digital tube displays [---], entering into fault operation mode. It will exit fault operation mode immediately after the sensor back to normal;
- Fault operation mode: Work for 10 minutes and stop for 20 minutes, repeating this cycle

Off Power Memory Function:
- When the power is restored, the temperature controller will run at the last set temperature

Package Included:
- 1 x Digital Temperature Controller
