Input power: DC 12V
Measurement input: NTC (10K 0.5%) Waterproof sensor Output: 1 relay output, capacity = 20A
5. Environmental requirements: -10~60°C Humidity 20%-85%
6. How to use: Connect the power supply and equipment to supply power to the controller. At this time, it is displayed as measuring temperature. Press SET once, the display's temperature will flash, press +- to set the target temperature (press and hold+- can quickly set the temperature). After the setting is completed, press SET to confirm the return. At this time, the controller automatically processes the relay on/off according to the setting!
The output of the temperature controller is a 20A relay, which meet various high-power loads. When the control circuit is connected, the temperature controller can be powered. At this time, the display shows the environment temperature.
Indicator light: flashing indicates cooling or heating start delay, always-on indicates that the relay is closed
Digital tube: displaying LL means the sensor is in open circuit, then please connect the sensor according to the instructions. Displaying HH means that it is beyond the measurement range and the temperature controller will disconnect the relay. Displaying --- means high temperature alarm.
7. Due to some human reasons, the internal setting of the temperature controller is at a mess. It takes a lot of time to set the time. In this case, you can use this function to restore the factory settings. In the shutdown state, press and hold + and - buttons at the same time. Then turn it on, and all the above parameters will be restored to the factory defaults.
