Easier quality: timing on, timing stop, and timing switch. Just plug it in and select heating or cooling system, then it worksno spinning required. LCD with accurate display. Connects to both cooling and heating systems simultaneously. The heating and cooling differential function can be set separately for precise temperature control during significant changes. Temperature alarm: alerts when temperature exceeds set limits or sensor errors occur, reducing the need for constant monitoring. Compressor delay protection included; temperature calibration available. Wide application: this thermostat allows precise ambient temperature control. Ideal for greenhouses, fish tanks, heaters, aquaculture, incubators, room temperature management, home use, and more. Intelligent temperature control: this timer-equipped thermostat automatically controls cooling and heating appliances with smart temperature and timing functions. Temperature range: -40C to 120C. Equipped with a cable temperature sensor for real-time measurement. High-definition LCD display provides clear, intuitive monitoring of all data for accurate real-time temperature control. Accuracy: +/- 1%. Timing accuracy: up to 10 minutes. F01: Cycle timing mode sets start (on) and stop (off) times for operating cycles. F02: Timing mode enabled currently disabled (delayed state). F03: Timing stop mode currently on; delay (stop time) turns off output after countdown completes. Output disabled. F04: Timer on/off mode current state is off; delay (start time) turns on, then delay (stop time) turns off after operation. After shutdown countdown, output turns off and exits operation. In timing mode, start and stop times are configurable. Specifications: Temperature range: -40C to 120C Accuracy: +/- 1% Timing accuracy: up to 10 minutes Rated voltage: 230VAC 50Hz Rated load: MAX 16A / 3680W Temperature display resolution: 0.1C Package includes: 1 x Thermostat Socket Displays measured temperature and allows setting of start and stop temperatures to control heating or cooling equipment. Simply plug in and select heating or cooling mode to operate. Features power-off memory storage and screen lock protection.
