Simpler quality: timed open, timed stop and timed switch; Just plug it in and select heating/cooling system, then it works, no spinning, 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 during large changes. Temperature alarm: when the temperature exceeds the temperature limit or when a sensor error occurs, temperature changes do not always need to be taken into account. Compressor delay cushion for compressor control and temperature can also be calibrated. Wide unit: This thermostat allows you to control the ambient temperature precisely. Greenhouse, aquarium, carbon crystal heater, aquaculture, incubator, room temperature control, home and other places are widely used. Intelligent temperature control This thermostat with timer can automatically control the switch for cooling and heating appliances and has the function of intelligent temperature control and intelligent timing. Temperature range: -40~120C Intelligent temperature sensor With this thermostat you can control the room temperature precisely. Equipped with cable temperature sensor for real-time measurement. LCD with accurate display High-definition LCD screen, clear and intuitive monitoring of all data, accurate real-time temperature control. Accuracy: +/- 1%, Time accuracy: MAX 10 minutes. F01: Cycle time mode Cycle time mode F01, according to the start time (open) / stop time (close) of the work cycle. F02: Time mode enabled F02 time mode enabled, currently in disabled (delayed) state enabled. F03: Time stop mode F03 time stop mode, power is on, delay (stop time) is off, stop countdown is complete, output is off and disabled output.
