The external temperature detector can monitor ambient temperature and allows users to set start and stop temperatures. Features include cycle timing, start and stop time settings, and timer switch functionality. 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: -72°F to 176°F (-40°C to 120°C). Accuracy: ±1%. Heating & Cooling Mode: The thermostat automatically selects heating or cooling mode based on the set temperatures. If the start temperature is lower than the stop temperature, it enters heating mode; if higher, it enters cooling mode. Timing Function: Equipped with cycling timer and countdown functions. Modes include: 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 viewing of current and set temperatures 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 temperature-sensitive environments.
