Hi
After talking to Vaillant's tech desk today, I am even more confused about their setups.
Basically I need 2 x Ecotech Plus 630 system boilers cascaded and I would like them both with weather compensation controls.
I understand that it's not possible to have 2 x VRC 470f controllers in each of the two zones. So I need a commerical VRC 630 boiler management system (which alone costs about 65% of one of the boilers). However, I want wireless room thermostats in each zone because the current ones are wired on the wall in stupid locations in warm rooms above radiators.
According to the tech people, wireless thermostats are not possible with the VRC 630.
I take it only Vaillant's weather compensation controls work with their boilers? And the VRC 630 is the only Vaillant control that will support two cascaded boilers?
I have requested a Vaillant rep come out but anyone with any experience in this kind of setup would be greatly appreciated.
