Simpler Quality: Timed opening, timed stop, and timed switch; just plug it in and select the heating/cooling system, then it works, no spinning, LCD with accurate display. Connect to heating and cooling systems simultaneously. Differential heating/cooling 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 don't always need to be considered. Compressor delay for compressor control and temperature can also be calibrated. Wide Application: This thermostat allows you to precisely control room temperature. Greenhouses, aquariums, coal crystal heaters, aquaculture, incubators, room temperature control, homes, and other places are widely used. Intelligent Temperature Control: This thermostat with a timer can automatically control the switch of cooling and heating appliances and has the function of intelligent temperature control and intelligent timing. Temperature Range: -40~120°C Intelligent Temperature Sensor: With this thermostat, you can accurately control room temperature. Equipped with a cable temperature sensor for real-time measurement. LCD with Accurate Display: High-definition LCD display, clear and intuitive monitoring of all data, accurate control of real-time temperature. Accuracy: +/- 1%, Time Accuracy: MAX 10 minutes. F01: Cycle Time Mode: F01 cycle time mode, based on the start time (open) / stop time (closed) of the working cycle. F02: Time On Mode: F02 time on mode, acts in the off state (delayed) activated. F03: Time Stop Mode: F03 time stop mode, power is on, delay (stop time) is off, the power-off countdown is completed, the output is turned off, and the output is out of operation. F04: Timer On/Off Mode: Timer switching mode F04, the current state is disabled, the delay (start time) is activated, and the delay (stop time) is disabled after it is activated. When the operation stop is completed, turn off the output and end the operation. In time mode, when start time / stop time.
