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.
Outdoor control is in
IDLE
mode
(No heating or cooling demand)
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.
Turn room thermostat
to
OFF
Push and hold button until the solid
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.
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.

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.
