DC 12V Heat Cool Temp Thermostat Temperature Control Switch Temperature Controller Dual LED Digital Display 2 Channel Relay

Specifications: Temperature range: -20 ° ~ + 100 ° Resolution: -9.9 ° ~ 99.9 ° paragraph 0.1 °, other temperature ranges 1 ° Temperature measurement accuracy: 1 ° Minimum temperature difference: 0.1 ° Refresh rate about: 0.5S Input Power: DC 12V Measuring input: 1 m NTC (10K 0.5%) alloy waterproof sensor Output: Two relay 10A Environmental requirements: -10 ° ~ + 60 ° Humidity 20% to 75% Size: 70mm * 39mm Instructions: Tips: Set the temperature when the buyer must ensure that the upper limit temperature is greater than the lower limit temperature, the system will work properly. Circuit connection: Connect the power supply with reference to the circuit diagram and load, the temperature sensor is missing or damaged digital tube will show "- - -", before using buyer must check the temperature sensor is installed. The temperature output 10A relay, to meet a variety of high-power load, make sure that the line is correct. LEDs, LED status descriptions: LED: Off indicates the relay off, ON means the relay is closed Digital: Display "- - -", 1, check the temperature sensor 2 is missing or damaged, heating mode, high temperature protection 3, cryogenic cooling mode protection. In protected mode relay automatically disconnected. Use keys: temperature control panel has three buttons, button + button - SET button Button +: Achieving Rapid accumulation value Key: - fast diminishing value SET key SET: Temperature set temperature and operating mode interface query interface parameter setting interface During the SET press SET press according to different times, the corresponding digital temperature limit will be blinking, you can set the upper and lower temperature through the key addition and subtraction. After setting 8s automatically save data or short press three times data can be saved. SET Press to enter the ac
