This document introduces the features and characteristics of the universal controller RWD62, which is used for comfort control in HVAC and refrigeration systems. The controller has independent electronic control functions and can select application programs through application numbers. It operates at AC 24V and the range of input and output values can be set. The controller can be set and changed through buttons or software tools.
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.
