Integrated Furnace Controller Board for Lennox Single Stage Furnaces manufactured by White Rogers. We just upgraded our furnace and we had this controller as a spare in the event the one in our old Lennox furnace failed. It has never been used and still in the original box with instructions. This is for a Lennox furnace with:

Single Stage
PSC Blower Motor
80V HSI Ignition

It's always a good idea to keep a spare controller on board in the event of a failure. The first time our original board failed we were without heat for 2 days while they located a board in the area.
