From the manufacturer's datasheet for WRF06 RS485 Modbus.
Overview
The WRF06 is a flush-mounted room sensor for temperature, humidity and air quality in living rooms and offices. It is designed to sit in a switch frame range and can be mounted alone or in a multiple frame. Operating elements for HVAC control can be added as an option. It connects to controller and display systems over RS485 Modbus RTU. Versions measure temperature, temperature and humidity, CO2, CO2 with VOC, or combinations of these. Humidity versions can also give absolute humidity, enthalpy and dew point. The frame is supplied.
