Overview

The WRF06 RC is a flush-mounted room temperature sensor that connects to controllers and display systems over RS485 Modbus RTU. It is designed to match the frames of common switch ranges, so it can sit alone or in a multiple frame. One version, DI4, has four digital inputs for floating contacts. The other, AO2V, has two 0 to 10 V outputs for heating and cooling or for a 6-way valve, and two digital inputs. It mounts in a standard 60 mm EU box at least 45 mm deep and is configured with software, DIP switches or jumpers depending on the type.
