Hello,

 The furnace is up and running, no problems.
I have a Broan air to air heat exchanger and would like to include the furnace interlock feature.
Ideally the A2A would run when the blower at the furnace is running and the other inputs to the A2A are met.

I see in the manual there is an interlock to the compressor but I see nothing for the blower.

 Am I off base here? Should I interlock to the compressor or is there another way.

Thanks for you help

Steve

Wondering if I can use G- Fan and C - 24v common at the furnace?
I know the terminals at the A2A unit.

I would do the opposite. Have the thermostat and geo tell the broan when to come on. I don't like to subordinate the heat to the air exchange.
A stat with ventilation control is a good fit (i.e. honeywell IAQ).

Just got off the phone w/Broan - they said R and G, looks like I'm good.

thanks
