Honeywell S9200U Integrated Furnace Control

Re: 80v Glow Plugs/Ignitors

Oftentimes, a furnace (particularly Trane) will appear to have a control board compatible with the Honeywell S9200U control board; however, if the model number does not appear in the S9200U manual DO NOT replace the original board with the S9200U. 

Why: Although the board appears to be compatible, some units use a 80 volt glow plug. The unit will function properly for a few days then the igniter will fail.
