Currently have an old Ecotec 428 (c2007) and am replacing with a new Ecotec 430.
I've been very happy with old system, nothing wrong with it but replacing / moving location as part of a bigger project.
I retrofitted weather compensation myself, its quirky but has worked fine for many years. I used the VRC430 with VR65 wiring Centre and VRT50 room stat.
Looking at new boiler, it would appear that very little if any of existing controls are compatible.
So I've bought a VRC700 with a VR70 wiring / control centre. God knows how you wire the VR70 to an existing DHW with 2 x 2 Port valves and a basic tank temperature stat????
Anyway, main question is what about the VRT50 room stat. It's now not listed as being compatible with anything apart from the Analogue Timeswitch 150?? It's not even compatible with the digital Timeswitch 160 (this appears to require an old school analogue theremostat)...totally bewildered by those combinations.
So, question is, are there options for a Vaillant eBus compatible room stat that isn't a massive box ala VR91?
