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. Differenti heating/cooling 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 room temperature with precision. Greenhouse, fish tank, coal crystal heater, aquaculture, incubator, room temperature control, home and other places are widely used. Intelligent Temperature Control This timer thermostat can automatically control the switch of cooling and heating appliances and has the function of intelligent temperature control and intelligent timing. Temperature range: -40~120C Intelligent Temperature Sensor With the thermostat, you can accurately control the room temperature. Equipped with a cable temperature sensor for real-time measurement. LCD Ave Precise Display High-definition LCD display, clear and intuitive monitoring of all data, precise control of the temperature in real time. Accuracy: +/- 1%, Timing accuracy: MAX 10 minutes. F01: Cycle timing mode F01 cycle timing mode, depending on start time (open) / stop time (closed) of working cycle. F02: Timing mode on F02 timing mode on, act in off state (delayed ) enabled. F03: Timing stop mode F03 timing stop mode, current is on, delay (stop time) is off , the shutdown countdown is completed, the output is turned off, and the output is Out of Service. F04: Timer on/off mode Timer switching mode F04 , the current state is disabled, the delay (start time) is enabled, and the delay (stop time) is disabled after it is enabled. After the downtime countdown is completed, turn off the output and exit the operation. In timing mode, when the start time / stop time.
