Program Unit Capacity Size Modes

Power-Up - Number displayed represents by integrated control unit size code (furnace
model and capacity). If three horizontal bars are displayed followed by continuous E203,
furnace control does not recognize unit size code. Configure per the following:

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 Program Unit Capacity/Size mode and
reset. (If second period expires or button is held less
than 5 seconds, control will automatically exit Program
Unit Capacity/Size 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.)
