Air Handler/Furnace
Terminal Strip
Connecting the HRV/ERV as illustrated will ensure
the Air Handler/Furnace Blower Motor is operating
whenever the HRV/ERV is ventilating.
Consideration must be given to competing
airflows when connecting the HRV/ERV in
conjunction with an Air Handler/Furnace Blower
system.
