Vaillant opentherm compatibility

[wattsie1987]

Hello lads are these Vaillant only controls for comp or are they opentherm compatible, seeing mixed opinions and some saying an ebus adapter is required? Cheers

Vaillant is ebus only. Not open therm
Mate. I use Vaillant’s cheap RF plug in stat. It is boiler plus compliant. I say cheap but it isn’t.

Which one bud? Looking at the honeywell rf2 pack 1 it's about 140 and complies with optimisation and automation but needs opentherm to do load comp aswell

VRT350F mate. If you are going down the route of a stat. Then the only ones you can fit on a Vaillant are the Vaillant ones.

Ok mate cheers are they very user friendly? My past experience with Vaillant controls most customers have struggled a bit.

Not really to be honest. But once set up they are ok.

Mmmm wish they'd make something more simple click in receiver with programmer in built and a basic wireless digi stat with an override button . It could do load comp from that. The problem I find is that their existing controls are capable of much more than combi heating control and it just baffles customers and is stressful showing them how to adjust the times ect.
