Operating my new EcoTEC Plus 831 combination boiler in conjunction with VRC430f results in one oddity. Although the Warmstart function (preheating of the DHW heat-exchanger) can be switched on at the boiler, with appearance of "C" on LCD display, the preheating does not work.
On the VRC430f controller, as set up by the installer, the HC1 registrations appear on the LCD display, but no DHW settings appear. In other words, all the DHW registrations and screens are blanked out. [This blanking out does not seem to be documented.]
I have reported the Warmstart issue to the installer, who has gone away to think about it.
Does anyone please know if this is correct --- is there a way to get the Warmstart to work in conjunction with VRC430f? Or is there an undocumented restriction?
[Otherwise the new setup seems to be working well --- in particular, the optimum start and carefully targeted CH flow temperatures. In my property, heating curve 1.5 seems to be about right.]
