Easier quality: 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 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. Wide device: 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. Intelligent Temperature Control This thermostat with timer can automatically control the switch of appliances cooling and heating and has the function of intelligent temperature control and intelligent timing. Temperature range: -40~120C Intelligent Temperature Sensor With this thermostat, you can accurately control the room temperature. Equipped with cable temperature sensor for real-time measurement. LCD With Accurate Display High-definition LCD display, clear and intuitive monitoring of all data, accurate real-time temperature control. Accuracy: +/- 1%, Timing Accuracy: MAX 10 minutes. F01: Cycle timing mode Cycle timing mode F01, according to the start time (open) / stop time (close) of the working cycle. F02: Timing mode enabled F02 timing mode enabled, currently in disabled (delayed) state enabled. F03: Timing stop mode F03 timing stop mode, current is on, delay (stop time) is off, stop countdown is completed, output is off and Disabled output. F04: Timer on/off mode F04 timer switch mode, the current state is off, the delay (start time) is on, and the delay (stop time) is off after it is turned on. After the downtime countdown is completed, turn off the output and exit the operation. In timing mode, when the start time / stop time.
