PT100 Cable Length: 50cm  Temperature range :-50-110 ℃ Dimensions: 48.5 * 40mm Temperature control mode: ON / OFF Control accuracy: 0.1 ℃ Hysteresis accuracy: 0.1℃ Refresh rate: 0.5S High temperature protection： 0-110℃ Supply voltage: DC 12V Static current: ≤ 35MA, attract current ≤ 65MA Output voltage: DC 12V; Output power: 20A relay Measurement input: NTC (10K 0.5%) Waterproof Sensor Environmental requirements: -10 ~ 60 ℃ ，Humidity 20% -85% How to use: Connect the power supply and the load, you can supply to the controller. It displayed as a measured temperature. Press the SET button, the display flashes the temperature; Press - to set the desired temperature; After setting press SET to confirm return; The controller automatically performs the relay by setting off. Lights, LED status descriptions: Indicator: Off The relay is switched off, Always indicate the relay is closed. LED: Shows LL is the sensor open, showing HH is out of range, the thermostat will be forced to close the relay, the display --- as high temperature protection. Note : Relay output interface is a switch, when it working ,these two ports are connected. If not work, these two ports are not connected. Pls know it .
