The RWD32/RWD82 universal controller is an independent electronic universal controller with P and PI response, which can be used for comfort control in HVAC and refrigeration systems. The working voltage is AC 24 V or 220 V, and the application can be selected by the application number. Two universal input points are used for Ni 1000, Pt 1000 resistance temperature sensors and 0...10 V signals. Units can be set to °C, °F, % or unspecified units. One three-digit output or two digital outputs, direct action and reverse action. A digital input for day/night conversion. All data can be entered or changed via the keys on the controller without additional tools.
The RWD32 and RWD82 are independent electronic general controllers for HVAC and refrigeration systems. They support AC 24 V (RWD82) or AC 230 V (RWD32) supply, offer configurable inputs and outputs, and can be programmed via front‑panel buttons or a PC software tool.
The manual covers mechanical design, mounting options (DIN rail, wall‑mounted protective housings ARG62.21/ARG62.22), electrical installation, wiring diagrams, and detailed technical specifications such as power consumption, weight, and sensor ranges. This manual is written in Chinese.
| Working voltage (RWD32) | AC 230 V ±15 % |
|---|---|
| Working voltage (RWD82) | AC 24 V ±20 % |
| Power consumption | 6.5 VA (RWD32), 3.5 VA (RWD82) |
| Weight | 0.465 kg (RWD32), 0.297 kg (RWD82) |
Programming can be done with the front‑panel buttons or via the 9‑pin interface using a Windows‑based software tool.
The RWD32 operates on AC 230 V, while the RWD82 operates on AC 24 V.
Day/night mode is controlled by digital input D1 (or the contact between D1 and M).
