Quality is easier: timed on, timed off, timed on and off; just plug it in and select the heating/cooling system, it works, no rotation, LCD display is accurate. Also connected to cooling and heating systems. The heating/cooling differential function sets cooling and heating independently for temperature control over large variations. Temperature Alarm Alarm: When the temperature exceeds the temperature limit or a sensor error occurs, it is not necessary to always consider the temperature change. Compressor time delay protection for compressor control and temperature can also be calibrated. Wide Device: This thermostat allows you to precisely control the temperature of your environment. Widely used in greenhouses, fish tanks, coal crystal heaters, aquaculture, incubators, room temperature control, and households. Intelligent temperature control This thermostat with a timer can automatically control the cooling and heating switches of electrical appliances, and has intelligent temperature control and intelligent timing functions. Temperature range: -40~120C Smart Temperature Sensor With this thermostat, you can accurately control the room temperature. Equipped with cable temperature sensor for real-time measurement. LCD display is accurate High-definition liquid crystal display, all data monitoring is clear and intuitive, real-time temperature control is accurate. Accuracy: +/- 1%, Timing Accuracy: Up to 10 minutes. F01: Cycle timing mode Cycle timing mode F01, according to the start time (on)/stop time (off) of the working cycle. F02: Enable timing mode F02 Timing mode enabled, currently disabled (delayed) enabled. F03: Timing stop mode F03 timing stop mode, the current is on, the delay (stop time) is off, the stop countdown is completed, the output is off, and the output is prohibited. F04: Timing on/off mode F04 timing on/off mode, the current state is off, the delay (start time) is on, and the delay (stop time) is on and then off. After the shutdown countdown is over, turn off the output and quit running. In the timekeeping mode, when the timing is started/stopped. Specification: Temperature range: -40~120C Accuracy: +/- 1% Timing accuracy: maximum 10 minutes Rated voltage: 230VAC 50HZ Rated load: MAX 16A 3680W Temperature display resolution: 0.1 Scope of delivery: 1 x thermostat socket It can display the measured temperature, set the start and stop temperature, and control heating or cooling equipment. Just plug it in, select your heating/cooling system, and it's ready to go. Power-off storage function; screen lock protection function.
