Easier quality: timing open, timing stop, and timing switch; just plug it in and select heating or cooling system, then it works—no spinning required. LCD with accurate display. Measuring range: 50–99°C. Resolution: 0.1°C. Accuracy: ±1°C (-20 to 60°C). The digital temperature controller supports 100–250V, 16A (max), and can connect to both cooling and heating systems simultaneously. The heating and cooling differential functions can be set separately for compatible temperature control during significant temperature fluctuations. Temperature alarm: alerts when temperature exceeds set limits or in case of sensor error, ensuring reliable monitoring. Compressor delay protection included; compressor control and temperature calibration available. This thermostat allows precise room temperature control. Widely used in greenhouses, fish tanks, aquaculture, incubators, coal crystal heaters, home temperature management, and other applications.
