Room Zone Controls VR90

VR 90 room/zone control (for use with VRC630 only)
A separate control can be connected to eight heating circuits (room/zone/ 1 … room/zone 8). The VR 90 allows a user to set the operating mode and the target room temperature. The control can take into account the actual room temperature measured by the built-in room sensor, if necessary. It is also possible for the user to adjust some parameters for the associated heating circuit (time program, heating curve etc.) and to select special functions (over-ride/party etc.). It is also possible to query the heating circuit, and show maintenance and fault messages for the boiler. The VR 90 control is connected to the rest of the control system via 2-core eBus cable to enable communication.
