The VR 32 is an eBUS coupler for use with ecoTEC plus and ecoCRAFT boilers. VR 32 is required for cascade installations and allows the VRC 630, VRC 700 and VRC 700f controllers to identify the boilers connected to it.
The VR 32 sits alongside the boiler’s main PCB and connects via an interface cable. A simple numbered rotary switch is used to set the address of the boiler and is connected to the relevant controller using the eBUS terminals.
