When the correct unit size code is displayed, release
button. Selected code will flash for 10-second period.
During that period, press and hold button for 5 seconds.
Integrated control will store code in memory and will
automatically exit Field Test mode and reset. (If second
period expires or button is held less than 5 seconds,
control will automatically exit Field Test mode and go
into Idle mode without storing unit size code. If this
happens, programming function must be repeated.)
Verify that the selected unit size code is correct and
stored in non-volatile memory by cycling the 24 volt
power to the furnace control. (At 24 volt power-up of
the furnace control, the 7-segment LED will display a
unit size code. If three horizontal bars display, the board
does not recognize the unit size code. The programming
function must be repeated.)
