Overview
The Vaillant VR 61/4 Wiring Centre is for use with the VRC 470/VRC 470f. The VR 61/4 mixer module was created to enable the integration of Vaillant's low voltage eBus controls into conventional 230 V S-plan installations, resulting in a complete system solution that includes an ecoTEC system or open vent boiler, a uniSTOR cylinder, and a control. When all of the components are provided by the same manufacturer, installation is made simpler. The VR 61/2 is an intelligent wiring centre that may be used to connect two central heating zones with separate time and temperature settings as well as two hot water zones. It is only compatible with Vaillant cylinders and the VRC 470 and VRC 470f weather compensators. A supplementary circulation pump or storage loading pump may also be connected.
- Maintains correct flow of water through the boiler
- For use with ecoTEC plus 48 and 64 kW
- Aids in providing a constant temperature supply of water to reach multiple heating circuits downstream of the low-loss header connection
- Designed for new clean systems up to 70 kW net input
