Smart Temperature Controller: Temperature range: -40°C-120°C, temperature control accuracy: ±1%. The controller outlet can automatically switch between heating and cooling modes and control heating/cooling during operation by setting the start and stop temperature equipment. Versatile Functions: The LCD screen displays the temperature control mode and 4 timing modes F01-F04. It also features temperature correction, screen lock protection, and a memory function (all current settings are saved after a power failure). Intelligent Time Control: This thermostat outlet can detect temperature, set on/off temperatures, and control cycle time, on-time, off-time, and time switching. Time interval: 0-99 hours and 59 minutes, time accuracy: up to 10 minutes. Maximum load: 16A (2), 3680W. 1.8m Temperature Probe: The thermostat outlet comes with a 1.8m cable temperature probe for connection to the measurement point, with a temperature detection range of -40°C ~ +120°C. Multiple Applications: This digital temperature controller intelligently manages temperature and time. It's commonly used in household wall heating and other applications such as greenhouses, aquariums, carbon crystal heaters, thermostat switches, mobile air conditioners, and intelligent aquaculture control. Product Description: Specification: 1. Rated voltage: 230VAC 50HZ. 2. Rated power: MAX 16A 3680W. 3. Temperature range: -40 ~ 120℃. 4. Temperature control error: ± 1%. 5. Temperature display resolution: 0.1℃. 6. Timing error: MAX 10 minutes. F01: Cycle Time Mode: Press the "MODE" button to switch to F01. Press the "SET" button to set the ON value (start hour/minute) and OFF value (stop hour/minute). The ON value is the system's working time, and the OFF value is the system's shutdown time. This mode is cycle time, which can control the system to work intermittently. F02: Synchronous Mode Enabled: Press the "MODE" button to switch to F02. Press the "SET" button and set the hours/minutes. In this mode, the system is controlled to operate at the specified time. For example, if CD ON is set to 30 minutes, the countdown starts, and the system automatically starts after 30 minutes. F03: Timer Mode: Press the "MODE" button to switch to F03. Press the "SET" button and set the hours/minutes. In this mode, the system is controlled to shut down at the specified time. For example, if you set CD OFF to 30 minutes, the countdown starts, and the system automatically shuts down after 30 minutes. F04: Timer On/Off Mode: Press the "MODE" button to switch to F04. Press the "SET" button and set the CD ON value (hour/minute) and CD OFF value (hour/minute). In this mode, the system is controlled to start and stop at the set time. For example, if you set CD ON to 30 minutes and CD OFF to 40 minutes, the system starts working after 30 minutes, and when the system starts working, it stops after 40 minutes.
