Measuring range: 50~99 degrees C. Resolution: 0.1 VS; Accuracy: 1C (-20~60C). This digital temperature controller supports all 100-250V, 16A (max.) and can connect to both cooling and heating systems simultaneously. The heating/cooling differential function can be individually set for temperature control during significant changes. Temperature alarm: when the temperature surpasses the limit or a sensor error is detected, temperature variations may not always need to be considered. Compressor delay protection is provided for compressor control, and temperature calibration is also possible. This thermostat offers precise room temperature control. It is widely applicable in greenhouses, fish tanks, coal crystal heaters, aquaculture, incubators, room temperature regulation, homes, and more.
