great i will ask for the kit what exactly does it do i would assume it just connects the two so you can run off one t-stat, its in a new house the power is not on.

Been a while since I've installed one, but it has a relay that wires to W and R (and possibly G) of the second furnace so that it is isolated from the first furnace but able to be controlled by a single stat. It also has a second door switch for your second furnace that breaks Furn 1 when Furn 2 panel is removed.

I don't do much residential installs anymore except for highrises. If I condemn it someone else puts it in.
Seventeen years at the same company has its priviledges. Now if only I could pick up a second weeks vacation.
