[Easy to use]: The temperature range of this temperature controller is -40-110. Easy to set up and adjust, equipped with a high-definition LCD display and 4 buttons. It is a relay temperature controller and requires additional power to be connected to the load. [High current 30A relay]: High power: 220V 30A. High-power equipment can be used, such as refrigerators, brooders, incubators, fermenters, greenhouses, etc. Connect power and heating/cooling equipment, place the probe and set the temperature, and it's ready to go. [Heating/cooling function]: Heating mode "H": When the detected temperature is less than or equal to the set temperature - hysteresis temperature, the relay is turned on and the heating device starts to work; when the detected temperature is greater than or equal to the set temperature, The relay opens and the heating equipment stops working. The principle of cooling mode 'C' is the same. [Delayed start and temperature correction function]: Delayed start 'OPH': When the heating or cooling work is completed, the system starts timing 'T'. When T is greater than or equal to OPH, the system can perform the next round of heating or cooling work. Temperature correction 'OFE' (-10.0-10.0): When the system works for a long time, deviations may occur, which can be corrected through this function. Actual temperature = measured temperature + calibration value. [High temperature alarm function]: When the actual temperature is greater than or equal to the alarm temperature, the system will turn on the sound and light alarm and disconnect the relay. Press any button to stop the sound and light alarm. light. Usage steps: 1. Connect the sensor to the controller. 2. Connect the controller power supply. 3. Adjust the start temperature, stop temperature and temperature correction. 4. Remove power supply. 5. 6. If necessary, connect power to the load at the relay output. 6. Reconnect controller power. 7.
