Vaillant VR66/2 Control Centre

Vaillant VR66/2 Control Centre Overview

The Vaillant VR66/2 Control Centre sits at the core of Vaillant’s Total System Solution, acting as the main hub that allows different heating controls and components to communicate with each other. It enables eBUS controllers to be connected with room thermostats, motorised valves, multi-zone heating systems, and domestic hot water cylinder systems, giving you greater control over your heating setup. This control centre is designed to improve the efficiency and flexibility of your heating system by allowing multiple heating zones to be controlled independently, or alternatively, by managing a single heating zone depending on the system requirements.

Multi-Zone and Mono-Zone Functionality

The VR66/2 Control Centre has two main operating modes: Multi-zone mode and Mono-zone mode. Multi-zone mode allows different areas of a property to be heated separately, making it ideal for larger homes or buildings where different rooms may require different temperatures. This mode is compatible with the VRT 350 programmable room thermostat and works with system, combi, and open vent boilers. Mono-zone mode is designed for simpler heating systems where only one heating zone is required. In this mode, the VR66/2 works with the Vaillant eBUS controller range and is suitable for system or open vent boilers.

Compatibility and Installation

The Vaillant VR66/2 is required when linking certain Vaillant controls to a heating system or open vent boiler. It is compatible with the VRT 350F, VRC 470, VRC 470F, and timeSWITCH 160 digital controllers. However, it is important to note that the VR66/2 is only compatible with the newer range of Vaillant ecoTEC boilers manufactured from March 2012 onwards. As a wiring centre, the VR66/2 helps simplify installation by providing a central connection point for heating controls and system components, ensuring reliable communication between devices and efficient system operation.
