The main control switch has three terminal connections - ?OC?, G, & B. The 20 minute switch also has three terminal connections - OC, OL, & I.
If these two switches were to be used together, where would terminals be connected to the 10-terminal connector block of the ventilator unit?

If space is limited, using the simplified return-return method can the ERV supply come from one central return duct and the ERV return be in another
In my basement, because of space restrains and finished walls, there is not enough of a straight return trunk exposed for me to use the minimum 13' (10' + 3') indicated in the instructions in a straight line. In my house I have three return ducts that meet in a large return that feeds into the furnace. I would be able to get adequate distance away from the furnace for the ERV duct work, but I would have to select one of the returns (in this case from the living room) to extract stale air and use another return line (basement) to supply the fresh air from the ERV which would ultimately lead to the furnace. Is this acceptable or do they need to be in a straight line?
Also, if you link the wiring as indicated in the instructions, is the system synchronized with the furnace blower operation?
