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 (-20–60°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 precise temperature control during significant fluctuations. Temperature alarm: alerts when temperature exceeds set limits or if a sensor error occurs, ensuring reliable monitoring. Includes compressor delay protection; temperature calibration is also supported. Wide application: this thermostat allows precise room temperature control and is widely used in greenhouses, fish tanks, incubators, aquaculture, heaters, home environments, and other temperature-sensitive settings.
