Baxi 600 without opentherm

[natcho_98]

I've got a Baxi 600 combi, with a Google Nest thermostat, fitted a year ago. I've just learnt about OpenTherm, so went into my Nest settings, and found that it is disabled (only on/off mode is selectable, OpenTherm gives an error message). I spoke to the installer who says that he never enables OpenTherm, it's more hassle than it's worth, and apparently I'm the first one to ask about it. Is it worth enabling? Does it really cause problems? How big a job would it be, presumably switching some wires?

Y,N, not very, precisely.

So, it's basically moving two wires on the heatlink, and two on the boiler? And it doesn't matter which way round they go?

Dosen't matter no, not polarity sensitive.
