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.
Outdoor control is in
IDLE
mode
(No heating or cooling demand)
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.
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 select 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.
