Digital Thermostat XY-WT02 — clear temperature control, Modbus integration, and reliable alarms Key benefits Precise, automatic temperature selection: when an 18B20 sensor is connected, the thermostat automatically uses the 18B20 temperature reading for control and display. Easy integration with control systems: supports the standard Modbus protocol for straightforward communication with PLCs, controllers, and monitoring systems. Safety and protection: configurable high and low temperature alarms for both heating and cooling modes to protect equipment and processes. Ready for wet environments: includes a waterproof temperature sensor for direct deployment where moisture resistance is required. Note: the 18B20 digital sensor is supported but not included. Main features Model: XY-WT02 digital thermostat Communications: standard Modbus protocol support for system integration and remote monitoring Sensor support: accepts 18B20 digital temperature sensors; automatically switches to 18B20 readings when connected Alarm functions: independent high- and low-temperature alarms in heating and cooling operation modes Sensor package: supplied with a waterproof temperature sensor; 18B20 digital sensor must be supplied separately if required Why customers choose the XY-WT02 Reduces manual monitoring by automatically prioritizing the connected 18B20 sensor for the most accurate digital readings Simplifies integration into building automation or industrial control networks through Modbus Enhances process safety with separate alarms for over- and under-temperature in either heating or cooling operation Provides immediate usability in damp or wet installations with the included waterproof sensor Typical applications HVAC and building automation: integrate into control panels to manage heating and cooling zones with Modbus data logging and alarm reporting Equipment and process protection: set high/low alarm limits to protect pumps, compressors, freezers, or heat-producing machinery Agriculture and labs: maintain stable temperatures in greenhouses, incubators, or fermentation tanks using the included waterproof sensor and optional 18B20 probes for more precise digital monitoring What is included / not included Included: XY-WT02 thermostat and a waterproof temperature sensor Not included: 18B20 digital temperature sensor (supported, must be provided separately) Order the XY-WT02 when you need a Modbus-compatible digital thermostat with automatic 18B20 sensor prioritization, reliable high/low alarms for heating and cooling, and a waterproof sensor for immediate deployment.
