I am just about finished installing my Rewaire ERV 130, just have a few more section of insulation to finish up with, but my question is related to the ERV as I will be calling Renewaire next week hopefully Monday or Tuesday.
What I would like to know, is if there's a way of controlling the ERV so that it runs only when there no call for heat ? The reason being is that when there's a call for heat and the ERV is running the return duct that I am currently using is not large enough to handle both the 130 CFM's plus the cold air the furnace is pulling in (roughly 430 CFM's) when in low fire (70% of the time)+ the 130 CFM's in the return that is approximately 11" X 11". So for a temp fix until I move to my next project which will include a separate return for the ERV built into my down stair closet I need to have the ERV run only when the furnace isn't calling for heat. My furnace is the Infinity 58MVC 60K. Any suggestion for a temp. fix?
