Easier quality: timing open, timing stop and timing switch; Just plug it in and select the heating/cooling system, then it works, no spinning, LCD with precise display. Measuring range: 50 ~ 99 degrees C. Resolution: 0.1C; 3. Accuracy: 1C (-20~60C). The digital temperature controller can supply all 100-250V, 16A (max.), connect to cooling and heating systems at the same time. The heating/cooling differential function can be set separately for cooling and heating for temperature control in case of major changes. Temperature alarm alarm: When the temperature exceeds the temperature limit or when a sensor error occurs, temperature changes do not always need to be considered. Compressor delay protection for compressor control and the temperature can also be calibrated. Wide device: This thermostat allows you to control the room temperature precisely. Greenhouse, aquarium, coal crystal heater, aquaculture, incubator, room temperature control, home and other places are widely used.
