NTERLOCKING TO A FURNACE
/
AIR HANDLER
The circuit board has three available “dry contact” relays. Contact 3 is not available.
Maximum 115V, 10 amp resistive load.
Contact 1
These relays initiate whenever the ERV is in defrost.
Contact 2 and 4
These relays initiate whenever the ERV fans are operating.
•
Use contact 2 or 4 to interlock the ERV to an Air Handler or Furnace.
Note: Connecting the ERV as illustrated will ensure the Air Handler Blower Motor is operating
whenever the ERV is ventilating.
Caution
•
Consideration must be given to competing air flows when connecting the ERV in conjunction
with an Air Handler/Furnace Blower system.
