Fujitsu RLS3H on 1st floor living room.
We have 2 exhaust and 1 supply upstairs. 2 exhaust are in 2 bathrooms. 1 supply is in MBR. The MBR is like 2 degrees colder than any other part of upstairs and it would be nice if the heat were a little more even.
My thought is the supply in the MBR should be turned into an exhaust making all of the HRV registers on 2nd floor exhaust, drawing up the air from downstairs. Thoughts ?
To compensate for turning the MBR supply into an exhaust, I think a large supply should be added, probably in the room with the heat pump head unit, to get good blending of cold and warm air (???).
Any thoughts on whether this will help? Hurt?
I know there was a GBA article about this, but it seemed like it was mostly speculation as to whether all exhausts upstairs would work well.
