SensoCOMFORT

Vaillant VR 32/B is an eBUS coupler used to cascade Vaillant aroTHERM heat pumps alongside the sensoCOMFORT range of controls. It comes with a housing. One VR 32B is required for each additional heat pump in the cascade. 

In cascade systems, a VR 71 wiring centre is also a requirement. A VR 70 may be needed on the control side alongside your sensoCOMFORT or VRC700 controls, and any additional thermostats based on the use case. (see sensoCOMFORT or VRC700 listings for more information).

This product is a universal bus coupler and is used to connect bus systems. This version is a galvanically isolated connection for eBUS systems.
