Siemens RWD62 General Controller User Manual
The RWD62 is a universal controller designed for HVAC and refrigeration comfort control. It can be mounted in a control panel or in wall‑mounted protective housings (ARG62.21/ARG62.22) and supports temperature, humidity, pressure, flow and indoor air quality measurements.
The controller offers two analog input points (X1, X2) for Ni 1000, Pt 1000 or 0‑10 V DC sensors, two analog output points (Y1, Y2) with selectable forward or reverse action, a digital input for day/night switching, and optional auxiliary functions such as PI limiting, remote set‑point, cascade control, set‑point compensation, winter/summer mode and maximum priority.
