Features:100% Brand new and high quality.Quantity: 1Applicable to Various spatial temperature control，Water temperature control，Incubators， etcMaterial : Plastic and metalTemperature range: -9-99 centigrade Accuracy: 1 centigrade Control accuracy: 1 centigrade Setting Range: -9-99 centigrade Refresh rate: 0.5SInput Power: DC12VOutput: relay output， capacity 220V 10A / 12V 10AEnvironmental requirements: -10-60 centigrade Humidity: 20% -85%Size: 78x51mmTemperature sensor: NTC(3950-10k 1%)Lights， digital tube， key state descriptionRed start Indicator:START (red) indicator light， which means that the relay is closed， the device begins to workGreen stop light:Stop (green) light is on， which means that the relay is disconnected， the device stops workingDigital TubeMiddle red LED display for the current detection temperature， the left green digital display tube as set start temperature， the right side of the green digital display for the set stop temperature1 High temperature start:Set the starting temperature value> stop temperature value，When the detected temperature ≥ start temperature， the relay is closed， refrigeration equipment work;When the detected temperature ≤ stop temperature， the relay off， refrigeration equipment stops working.For example: Set the starting temperature is 30 centigrade ， stop temperature is 25 centigrade ，When the detected temperature ≥ 30 centigrade ， the relay is closed， the start Indicator (red) lights;When the detected temperature value ≤ 25 centigrade the relay off， stop Indicator (green) light.2 cold start: start temperature set valueWhen the detected temperature ≤ start temperature relay is closed， the heating device operates;When the detected temperature ≥ stop temperature， the relay off， the heating device is stopped.For example: Set the starting temperature is 25 centigrade ， stop temperature is 30 centigrade ，When the detected temperature value ≤ 25 centigrade ， the relay is closed， the start Indicator (red) lights;When the detected temperature ≥ 30 centigrade ， the relay off， stop Indicator (green) light.3 set to start when the temperature value = stop temperature value， the relay offPackage Include:1PC Temperature Control with NTC temperature sensor(without retail package)
