The new Wago 207-4301 heating junction box simplifies the installation of central heating and hot water systems. In this video, we run through the wiring of an s-plan system for hot water and a single-zone central heating system.
We include a step by step wiring diagram and a link to a downloadable version.
The Wago heating junction box is available fully populated or as a chassis to configure your own terminal block arrangement. We build this version from Wago 221 – 3 and 5-way variants to create what we believe is a logical layout for s-plan heating systems.
