When the correct unit size code is displayed, release
button. Selected code will flash for 10-second period.
During that period, press and hold push button for 5
seconds. Integrated control will store code in
memory and will automatically exit Program Unit
Capacity/Size Mode and reset. (If second period
expires or push button is held less than five seconds,

storing unit size code. If this happens, programming

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
