Hi folks, I'm working on a Honeywell ER200 Ventilation system (temp and humidity exchanger) that has been incorrectly installed, and I'd like to get your input on the extent of the fix needed. The system is geothermal. Below is my diagram that shows how it is, how it should be, and how I'm thinking of doing it.
Does the fresh air return have to be before the air handler or can I run it to a point after the AH to use the existing duct junction? This will result in some air bypassing conditioning, and I can see how it would be undesirable, but I guess I'm wondering how undesirable if so :)
