Note: This product has three buttons and three status indicators, two output indicators. Description: It is difficult for human senses to perceive small temperature differences. When an environment needs constant temperature, why not buy a thermostat, which can accurately measure and control the temperature in the room, and the intelligent digital display function makes the temperature value clear at a glance. Features: Temperature control accuracy: Small error, accurate data, suitable for constant temperature. Wide-voltage power supply: Even if the voltage is unstable, it can work, and it can adapt to a certain power supply voltage change. High-precision probes: High-precision probes can accurately measure data and show you more accurate values. Power-off protection function: High temperature setting and low temperature setting have anti-power-down function, and after the power is turned off, it is still convenient to quickly reset the temperature value you previously set. Accurate temperature control: Dual relay output, which can connect cooling and heating systems at the same time. The heating/cooling differential function can be set to protect the cooling and heating separately to control the temperature that changes drastically. Compact and space-free: Small and compact, it does not occupy large space and is easy to place. The operation is simple: Set the temperature corresponding to high temperature and low temperature separately, and then the self heating or cooling will occur when the temperature exceeds the set range. Specifications: Output Current: 10A Sensor: NTC (10k) Working Voltage: AC110V-250V Operating Frequency: 50Hz-60Hz Temperature Range: 0-99°C Temperature Control Range: 0-99°C Refresh Frequency: 0.2s Temperature Accuracy: ±1°C Load Power: 2200W Environmental Requirements: -Temperature: -10°C~60°C -Humidity: 20%~85% Output: Two Relay Outputs (Heating, Cooling) Packing List: 1 * Thermostat 1、Temperature control accuracy: Small error, accurate data, suitable for constant temperature. 2、Wide-voltage power supply: Even if the voltage is unstable, it can work, and it can adapt to a certain power supply voltage change. 3、High-precision probes: High-precision probes can accurately measure data and show you more accurate values. 4、Power-off protection function: High temperature setting and low temperature setting have anti-power-down function, and after the power is turned off, it is still convenient to quickly reset the temperature value you previously set. 5、Accurate temperature control: Dual relay output, which can connect cooling and heating systems at the same time.
