This is an excellent and practical multifunctional device that is used to control the temperature and humidity of the air environment to make your work easier. Please do not soak in water.<br>Widely used: various sensor control boxes, water heaters, refrigerators, fans, etc.<br>Input voltage: AC110~220V and relay output: maximum charging current 10A. Temperature and humidity control can be realised at the same time. Temperature and humidity correction can be realised.<br>Temperature range: -20~80C; Humidity range: 0%~100%RH<br>Microcomputer thermostat with intelligent digital display and built-in 1M sensor, dual display. Flame Retardant ABS Plastic Housing<br><br>Product description:<br>Switch the modes between cooling and heating; control the temperature by adjusting the temperature setting value and the differential value;<br><br>Temperature calibration: cooling control output delay protection; temperature exceed, temperature limit or sensor error alarm.<br><br>Heating and cooling mode setting.<br>Setting (start temperature):<br>Press and hold the button 3 seconds until the start temperature flashes. Use the button to set the value for the start temperature.<br><br>Setting (stop temperature):<br>Press and hold the button 3 seconds to stop the flashing of the temperature. Use the button to adjust the value of the stop temperature.<br><br>Set start temperature (humidity):<br>Press the "Up" button once to show the start temperature (humidity). Press and hold the "On" button for about 3 seconds. The desired temperature (humidity) can be adjusted with the up and down buttons<br><br>Set stop temperature (humidity):<br>Press the "Down" button once to display the stop temperature (humidity). Press and hold the button for about 3 seconds and the number of stop temperature (humidity) flashes. The desired temperature (humidity) can be adjusted with the up and down buttons<br><br>Temperature/humidity correction:<br>Press the "Up" and "Down" buttons at the same time.<br><br>Function:<br>temperature and humidity at the same time.<br>Can be connected to humidifier and dehumidifier devices at the same time.<br>Be able to connect with cooling/heating and moisture<br><br><br><br>
