Going mad about system boiler efficiency - HELP!

[Knappers]

Ideal logic has two switch inputs I believe

Thanks Shaun. Really don't like Ideal tho.
I swear I'm not being intentionally awkward.
I might go for intergas but never fitted one before (have you/what do you think of them?), or look for controls to do it on baxi/worcester - like evohome (without trv's).
I really liked my (now old and clunkey) vaillant VRC 430 for functionality - like it has legionella/pasturising cycle and actually came with a full manual!

tbh us as engineer have gone lazy / not needing tech controls like in the commercial game you think what a standard dom house requires with combi or heat just standard on or off if you can get you hand on an old Viessmann you can do what you want eg wc with internal room influence etc

Have a look at the 200e from Viessmann’s I think that’s compatible with the new version

I did fit a Viessmann 200-w a few months back but with vicare, which just had a room sensor and adjustable curve on boiler. lack of thermostatic control inside was a step too far for customer to get their head around and ended up swapping it out for 3rd party controls.
Did say they're bringing out a 200e type control for vicare wifi system and I'll prob be all over that when they do.
Currently I like worcester as a complete system inc controls (I like matching boiler & control) but this system boiler efficiency hole is bothering me.
There definitely was a clear split for a while before legislation prompted the rush to dumb down efficient controls. To be fair tho I couldn't sell good controls 10 years ago and now everyone wants 'smart' controls. So I don't know perhaps it's all good...?
