Digital LED Microcomputer Thermostat Controller Switch Temperature Sensor 12VBrand New:Temperature measurement range: -50Celsius-110CelsiusTemperature 0.1,other paragraph 1 CelsiusAccuracy: 0.1CelsiusReturn difference accuracy: 0.1CelsiusRefresh rate: 0.5sHigh temperature protection: 0-110CelsiusThe input voltage: DC12VMeasurement input: NTC (10K 0.5%) waterproof type sensorOutput: 20 a relay all the wayEnvironmental requirements:-10Celsius,-60Celsius humidity 20%-85%Size:47.5mm(length) x 28.7mm(width) x 32mmHole size: 46 x 26.5mmIntroduction:Power consumption: Static current 35MA pull current: 65MAConnect the power supply and the load supply to the controller. The currently measured temperature (top) is displayed as red. The desired temperature to be set (bottom) is blue. Press STC (+) C / F (-) to set the desired temperature. 3 seconds after setting just confirm that it has been set, then the controller will automatically execute. The thermostat output is 10A relay which meets a variety of high-power loads, but just make sure that the line is connected correctly.LEDs, LED Status Description.LED: Off indicates the relay off; Always indicates the relay is closed.Digital tube: if the open display HH LL sensor measurement range is exceeded, the thermostat will be forced off the relay display. This is high temperature protection.The package includes:1pc x Thermostat Controller1pc x Temperature Sensor
