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 heating systems, 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: -72F to 176F (-40C to 120C). 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 activates heating mode. If the start temperature is higher than the stop temperature, it activates cooling mode. Timing Function: Offers cycling timer and countdown functions. Modes include: F01 Cycle Timer; F02 Countdown ON; F03 Countdown OFF; F04 Countdown ON and OFF. Timing range: 0 to 99 hours 59 minutes. Backlit LCD Display: Enables clear viewing of current and set temperature values in low-light conditions. Includes calibration, memory retention, and reset functions for enhanced usability. Wide Application: Suitable for use in greenhouses, homes, reptile enclosures, incubators, terrariums, refrigeration units, vivariums, fermentation setups, and other environments requiring precise temperature control.Specifications: Plug Type: EU, US, UK, AU (optional) Working Voltage: 240V (AU), 230V (EU & UK), 110V (US) Maximum Working Current: 10A (AU), 13A (UK), 15A (US), 16A (EU) Material: PC flame retardant material Temperature Display Range: -40C to 120C Temperature Display Resolution: 0.1C Accuracy: 1% Timing Accuracy: Up to 1 minute deviation Standby Power Consumption: Less than 0.8W Package Weight: 165g (5.82oz) Package Size: 8.2 x 6.5 x 10.4cm (3.23 x 2.56 x 4.09in) Package List: 1 x Temperature Controller 1 x User Manual (English)
