Note: To determine which wires from your ERV/HRV need to be
connected to the ACC+/ACC- terminals on your ecobee3, you
will need to refer to your ERV/HRV manual. The two wires will
be listed under configurations that enable “optional auxiliary
control for high speed fan” or “dry contact timer configuration”.
