Configuring Unit - Lennox XC25-024-230-01 Installation And Service Procedure

Configuring Unit

When installing a replacement outdoor control, the unit selection code may have to be manually assigned using the 7-seg­
ment display and push button on the control. The unit code sets unit type, capacity and outdoor fan RPM.
Power-up - Unit selection code (two-digit number) displayed
represents unit size code (outdoor unit capacity).
During initial power-up, firmware version, unit type, unit capacity
and unit selection code will appear on the 7-segment display.
If three horizontal bars are shown in the 7-segment display
during power-up, the outdoor control did not store the last
configuration setting. If this happens, the configuration se­
quence for that setting must be repeated.
To enter unit selection
mode, push and hold the
button next to the 7-segment
display until dash symbol
appears and immediately
release button. Once dash
starts flashing, proceed to
next step.
Push and hold button until the solid
PU sequence is displayed on the
7-segment display then immediately
release the button. This
configuration sequence allows the
installer to select unit selection code
(number combination) that matches
the outdoor unit type and inverter.
Press and hold the button during
the PU cycling display.
NOTE - Either the PU sequence
will repeat 5 times and if a
selection is not made the control
will return to idle mode.
SELECTED
If three horizontal bars display in any
part of the 7-segment display string
during power-up, the outdoor
control did not store the unit
selection code. If this occurs, the
configuration sequence for that
section of the display string must be
repeated.
