Easier quality: timing open, timing stop, and timing switch; simply plug in and select the heating or cooling system to operate, no spinning required, with an LCD for accurate display. Measuring range: 50–99 degrees 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 precise temperature control during significant fluctuations. Temperature alarm: alerts when temperature exceeds set limits or in case of sensor error, ensuring reliable monitoring. Compressor delay protection included, and temperature calibration is available. This thermostat provides precise room temperature control and is widely used in greenhouses, fish tanks, heaters, aquaculture, incubators, home environments, and other applications.
