Configuring Unit Selection Code - Lennox XP25-024-230-01 Installation And Service Procedure

Configuring Unit
When installing a new or replacement outdoor control, the unit selection code may have to be manually assigned using the
7-segment 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 appears 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 code,
push and hold button next
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 choose the unit selection
code (number combination) that
matches the outdoor unit type and
inverter.
Press and hold the button during
the PU cycling display.
NOTE: The PU sequence repeats
5 times. If a selection is not made,
the control returns 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.
