This upgrade kit is for Thelin Gnome pellet stoves that were made prior to 2005. This older Gnome pellet stove has a rotary dial control vs. newer units that have push buttons.
The update kit is for a new controller, motherboard, and mounting bracket. The firmware includes the 16.6 microchip (for 1992-2003 models) which was the last non-auto ignition revision of the software. Contrary to what Thelin may tell you or publish on their website, this controller does NOT have to be sent back to Thelin for programming, the firmware INCLUDED.
This controller replaces an outdated version which is now obsolete. The update is the original programming and still will not support electronic ignition. There is no way to convert these older style Gnomes without auto-light to auto-light.
