Hi -
I'm having a new Vaillant ecoTec 630 boiler installed and I want to know how I can make it run most efficiently with a megaflo plus two central heating (radiator) zones. From reading Vaillant's website, it sounds like a VRC430, VR61 + VR81 is what I need, but I've also read there are some difficulties getting the megaflo's temperature sensor to play well with the VR61. Has anyone got any advice on how this should be done?
Thanks in advance...
