Ok, there's a couple of ways to do this.

-Damper opens no matter if the furnace is running or not. (Most simple)
-Damper only opens when there's call for heat. (need a relay)
-Damper opens and forces fan on. (need relay and little more complex, and I would not advise this for cold winters)

No, you will have to buy a relay for this.

You need to order the 90340 relay.

Are you using a damper or a HRV system for this set up?
