The Vaillant remote room zone control is designed exclusively for use with the VRC 630. The VRC 630 can connect to up to eight VR 90 controls. The VR 90 has an operating mode and a target room temperature that can be set by the user. The user can programme up to three time periods and choose between a five-day, two-day, seven-day or 24 hour operation. If necessary, the control can consider the actual room temperature as measured by the built-in room sensor. The user can modify some parameters for the associated heating circuit and choose special functions. It is also possible to view boiler maintenance and fault messages. To enable communication, the VR 90 control is connected to the rest of the control system via a 2-core eBUS cable.
