NFC and Supported App Method
This furnace control board is also equipped with NFC (Near Field
Communication) technology which allows the adjustment of operating
parameters, diagnostics, and service via a field-supplied mobile device
with NFC capability and supported mobile app. Remove 115-V power
from the furnace control board to use this method. See Fig. 38 for the
location of the NFC antenna. Additional instructions and help may be
available through the supported mobile app.
Scan the mobile app QR Code on page 1 of this manual for more
information and a link to download the mobile app.
Control Board Replacement
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.
