Have a W-M Gold CGa6 boiler with two heating zone circulating pumps (on the supply side to each zone) controlled by room tstats. I'd like to add a bypass to prevent condensation because the boiler return water doesn't always heat up to 130 degrees before the tstats turn off the circulators and, in turn, the boiler. CGa manual has a sketch and instructions on how install the bypass. Simple enough but I'd also like to add an outdoor reset controller. W-M manual warns not to apply their sketch if using an outdoor reset controller and to contact the local W-M rep for suggested piping and control methods. Unfortunately, local W-M rep wasn't any help. Any recommended piping and control schemes on how to utilize outdoor reset while at the same time preventing boiler condensation?
