DC 5V/12V/24V Mini LED Digital Temperature Controller Switch Refrigeration/Heating Control Relay Output 1. Using high-quality materials, the quality is guaranteed 2. Stable performance and long service life 3. Accurate temperature measurement 4. Small and beautiful appearance 5. Wide application Temperature control range: -20℃~+100℃ Resolution: -9.9℃~99.9℃ section 0.1℃, other temperature sections 1℃ Temperature measurement accuracy: 1℃ Hysteresis: 0.1℃ Refresh rate: about 0.5S Input power: DC5V/12V/24V (optional) Measurement input: 1m NTC (10K 0.5%) metal waterproof sensor Output: Relay output Environmental requirements: -10℃~+60℃, humidity 20%~75% Size: 46mm*40mm Instructions for Use: Circuit connection: Refer to the circuit diagram to connect the power supply and load, and the digital tube will display the actual measured temperature value. If the temperature sensor is missing or damaged, the digital tube will display ''- - -'', and the buyer must check whether the temperature sensor is installed before using it. The temperature control output is a 10A relay, which can meet various high-power loads. Please ensure that the wiring is correct. Indicator light, digital tube status description: Indicator light: off means the relay is disconnected, always on means the relay is closed Digital tube: display ''- - -'', 1. Check that the temperature sensor is missing or damaged 2. High temperature protection in heating mode 3. Low temperature protection in cooling mode. In protection mode the relay automatically opens. Use of buttons: There are three buttons on the thermostat panel, button + button - setting button SET Button +: Realize rapid accumulation of numerical values Button-: Realize the rapid decrement of the value Setting key SET: switch between three-layer interface, measured temperature interface, temperature setting interface, parameter setting interface Short press SET, the digital tube will flash, and enter the temperature setting interface. At this time, the temperature is set by pressing the button + or the button -. After the setting is completed, short press SET again to save the data or wait for 5s to save the data automatically. Press and hold SET to enter the parameter setting interface, P0-P4 are the corresponding parameter setting items. In the parameter setting menu, P0-P4 can be switched by pressing + or -. When you want to modify a certain parameter, you can switch to a certain item, short press SET to enter, and then perform key addition and subtraction. After setting, press and hold SET to save the data, or wait for 6s to automatically save the data. P3 setting 1 means that the thermostat stops running for 1 minute, and can be triggered again by short pressing SET. P4 setting 1 means that the thermostat starts to work after 1 minute. After setting, the nixie tube will not light up until 1 minute later will work normally. Short press SET to trigger again. Package Included:
