Control Board Replacement
for
If the control board must be replaced, the new board must be
programmed with the correct Model Program Number before the furnace
will operate. Do NOT program the control board with a Model Program
Number different than what is specified on the rating plate. The control
may be programmed by either of these approved methods:
1. Use the supported mobile app to flash the model program onto the
board using Near Field Communication (NFC). Scan the QR code
on page 1 of this manual for more information and a link to
download the mobile app.
2. Use the correct Super Plug (available from distributor / replacement
component) for the control board to copy the correct model
program onto the new board.
Further details and instructions for these programming methods are
provided with the replacement control board.
