timing open, timing stop and timing switch; Just plug it in and select heating/cooling system, then it works, no spin, LCD with accurate display. Connect to cooling and heating systems at the same time. The heating/cooling differential function can be set separately for cooling and heating for temperature control in case of major changes. Temperature 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. This thermostat allows you to control the ambient temperature precisely. Greenhouse, fish tank, coal crystal heater, aquaculture, incubator, room temperature control, home and other places are widely used. This thermostat with timer can automatically control the switch of appliances cooling and heating and has the function of temperature control and timing. Temperature range: -40~120CWith this thermostat, you can accurately control the room temperature. Equipped with cable temperature sensor for real-time measurement. High-definition LCD display, clear and intuitive monitoring of all data, accurate real-time temperature control.
