Configuring Unit Size Code
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:
Furnace control in IDLE mode
No heating, cooling or indoor fan
operation)
To enter Field Test
Mode: push and hold
button next to
7−segment LED display
until solid dash symbol
appears. Release
button.
Turn room thermostat to OFF
Push and hold button until the solid P
symbol is displayed on the 7−segment
LED. Release button. This mode allows
the user to select a unit size code number
that matches the furnace model size and
capacity.
Solid P starts
blinking on
7−Segment LED
Push and hold button. Integrated control will
display unit size code number for each
furnace model for five seconds.
When the correct unit size code is displayed,
release button. Selected code will flash for
10−second period. During that period, hold push
button until code stops blinking (disappear for 2
seconds). Integrated control will store code in
memory and will automatically exit Field Test Mode
and reset. (If second period expires or push button
is held less than five 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, board does not
recognize unit size code. Programming
function must be repeated)
Yes
No
IMPORTANT: Field replacement controls may
need to be manually configured to validate
furnace unit size code.
