XY-WT02 Digital Thermostat - Alarm for high and low temperatures during heating or cooling to prevent expensive or unsafe conditions. - Compatibility and sensing - The digital thermostat XY-WT02 supports the standard Modbus protocol and the 18B20 sensor. - When the 18B20 sensor is connected, the temperature automatically switches to the 18B20 test temperature. - Sensor configuration - Includes a waterproof sensor. - 18B20 digital sensor is not included. - Practical applications - Use in automation systems that communicate via Modbus for precise temperature monitoring and alarm triggering. - Suitable for environments where 18B20 sensors are preferred for temperature sensing, with automatic switching when connected. - Ideal for damp or wet environments requiring a waterproof sensor while maintaining compatibility with non-included 18B20 digital sensing options.
