Easier quality: timing open, timing stop and timing switch; Just plug it in and select heatingcooling system, then it works, no spin, LCD with accurate display. Measuring range: 50~99 degrees C. Resolution: 0.1 VS; 3. Accuracy: 1C (20~60C). The digital temperature controller can supply all 100250V, 16A (max.), Connect to cooling and heating systems at the same time. The heatingcooling 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 have to be taken into account. Compressor delay protection for compressor control and temperature can also be calibrated. Wide device: this thermostat allows you to control the room temperature with precision. Greenhouse, fish tank, coal crystal heater, aquaculture, incubator, room temperature control, home and other places are widely used.
