Use contact 2 or 4 to interlock the HRV to an Air Handler
or Furnace.
Connecting the HRV as illustrated will ensure the Air Han-
dler Blower Motor is operating whenever the HRV is venti-
lating.
Contact 2 and 4
These relays initiate whenever the HRV fans are operat-
ing.
Consideration must be given to competing air-
flows when connecting the HRV in conjunction
with an Air Handler/Furnace Blower system.
