VR 90 room/zone control
A wired room/zone control for use with the VRC 630 only
- Enables users to set the target room temperature and various heating modes
- Includes a built-in room sensor
- View maintenance and fault messages for connected boilers
- Connects via 2-core eBUS cable
The VR 90 is designed to be used alongside the VRC 630 on commercial heating systems, where up to eight VR 90 controls can be connected to the VRC 630. The VR 90 enables a user to set the operating mode, target room temperature and program up to three time periods over 24-hours, 2-days, 5-days or 7-days. The control can take into account the actual room temperature measured by the built-in room sensor and provides additional adjustment of some parameters for the associated heating circuit (time program, heating curve etc), in order to select special functions (over-ride/party etc). It is also possible to view maintenance and fault messages for the boiler for a simple diagnostics overview. The VR 90 control is connected to the rest of the control system via 2-core eBUS cable to enable communication.
