Hi,
In the process of installing a Heatmiser UH8 wiring centre with out Vaillant 637 ecotec plus. The Vaillant has a permanent feed (L E N) and a 230v RT connection.
I'm just trying to work out the right way of installing the 'Boiler Enable'. Heatmiser say it's a 'volt free' switch, which I believe is just like a relay (i.e. it just makes and breaks contact similar to a light switch).
I've put a few notes on the image below how I was proposing to do it - the heat enable making and breaking a live feed from the boiler spur - but wanted to check I wasn't going mad and doing something bad.
Thanks in advance!
