Navien combi boiler and evohome opentherm problem

[bheading]

Bit far. Buy a cheap OT stat, 30 quid, and try it. Do you have Plumb Centre/Wolseley?

Yes, Woseley's about a mile away. Either way it's easy to lay hands on that stuff.

I am pondering whether to be a little more radical and purchase something like this so that I can inject commands in between the Honeywell gateway and the boiler. That should definitely work if nothing else does.

has the boiler manufacture/ importer been asked,they will have the answers (eventually) Why make life hard-work

Up the nav's u r up the nav's

Yes, they have been asked and are investigating.

On my phone so can't really see the site well. Not sure all gateways give control, they just show what's happening. I have one though a different model. If you search for converting Vokera RF stat to OpenTherm on YouTube you'll get an idea what might show up on a Navian boiler. Wolseley have a part number for a low price deal, I can find it if you like otherwise it's twice the price.

Yes that would be great!

Wolseley branches are not always aware of the offer and sell the stat at list, you need the part number (I'm assuming the offer is still available)

Tbh it is not diy but others will argue=persons of entitlement (kind of person who disobey all existing guidelines including covid19)

Its so easy to professionally adapt that nav,there is a clue there

love the nav £$£ there currently ok appliances but they need professional installation including anything attached including accessories like many new uk boiler imports,

Yes your getting the idea,they are not for diy fiddling

Others will have different opinions,geographical location of the install is a factor
