The external temperature detector can monitor environmental temperature. Users can set start and stop temperatures, cycle timing, start and stop times, and timer switch functions. It is widely used in intelligent temperature control applications such as carbon heating, aquaculture, greenhouses, and home environments. Features: Plug and Play: Easy to program and safe to use. Simply plug the temperature controller into a socket, select the timing mode, and set the start and stop temperatures to control heating or cooling devices. Temperature Control Range: -40°C to 120°C (-40°F to 248°F). Accuracy: ±1%. Heating & Cooling Mode: The thermostat automatically determines the operating mode based on the set temperatures. If the start temperature is lower than the stop temperature, it activates heating mode. If the start temperature is higher than the stop temperature, it activates cooling mode. Timing Function: The thermostat offers multiple timing modes: F01: Cycle Timer mode F02: Countdown ON mode F03: Countdown OFF mode F04: Countdown ON and OFF mode Timing Range: 0 to 99 hours 59 minutes Backlit LCD Display: Enables clear visibility of current and set temperature values in low-light conditions. Includes calibration, memory retention, and reset functions for added convenience. Wide Application: Suitable for use in greenhouses, homes, reptile enclosures, incubators, terrariums, refrigeration units, vivariums, fermentation setups, and other environments requiring precise temperature management.
