New Boiler Advice

[GraRob]

From the two terminals in the boiler 24 volts out through the stat then these 24 volts come back. Don’t connect 240v pr the board is toast.

Supplier is recommending this?

Recommendations welcome!

Sorry about that, thought I was answering a different thread. You can use that stat which has a timer in it and just not use the onboard clock of the boiler.

You could also convert it to open therm which would give you more information on the boiler and run it a little more efficiently. Look on you tube for how to convert the Vokera rf stat to OpenTherm for details if interested.

Don't think so, there are two stats there, one a programmable stat the other a stat only. Either will do.

Just front box pic, theres a transmitter and receiver in the box.

Ok, you have the programmable version. You have two ways to go

Set boiler clock to 24 hrs and use the 1 hour timings on the room stat.

Set the room stat timings to 24 hours and use the boiler clock.

Your installer will know what I mean

"Set boiler clock to 24 hrs and use the 1 hour timings on the room stat" eg: always on?

Yes, otherwise you'll have two time schedules. Cut off plug. Red and black into the black link in the boiler contr box. Brown and blue to power terminals.

Thanks very much, i watched a few YouTube videos last night.I didn't realise how much was possible using open therm configuration, I've got the installer to wire it up that way.
Great tip. Thanks

It's only the beginning and the higher the spec boiler the more it can do. I can repressurise my system from the room control but we will not release that in the UK; maybe ever. Great to check pressure or reset boiler if in the loft (not on your model).
