Evolutionr Connext Wall Control does not power up:
1. Recheck the wiring to the ABCD connector on all devices.
Make sure all colors match for every terminal.
2. Make sure power is applied to the indoor unit, and the Yel-
low and Green LEDs are lit on the Evolutionr Damper
Control.
3. Check for 24 VAC between the C and D terminals at the
Evolutionr Connext wall control terminal block.
4. Check the fuse at the indoor unit circuit board, and the Evo-
lutionr Damper Control.
Evolutionr Connext Wall Control display says "Indoor Unit
Not Found:"
1. Recheck the wiring to ABCD on all devices. Make sure all
colors match for every terminal.
2. Press the side button at the Evolutionr Connext wall con-
trol to try again.
3. Check for power to the indoor unit.
4. Disconnect all ABCD connections from every device and
only reconnect the Evolutionr Connext wall control to the
indoor unit. If the indoor unit is identified by the wall con-
trol, then another device on the ABCD connection may be
at fault. Reconnect each device's ABCD connection one at a
time and perform a Re- -Install from the Service Menu after
each connection is made. If one or more devices are not
found after reconnecting the last device, the last device may
be suspect.
5. If the ABCD connection only contains an indoor unit and
an Evolutionr Connext Wall Control, then the wiring, in-
door unit control board, or Evolutionr Connext Wall Con-
trol may be at fault.
Evolutionr Connext Wall Control display says "Outdoor
Unit Not Found" when applied with a two- -speed communicat-
ing outdoor unit:
— Recheck the wiring to the ABCD connector on the
outdoor unit. Make sure all colors match for every
terminal.

Evolutionr Connext Wall Control cannot find Zones 5 - - 8:
1. Make sure zone module 5 - - 8 has the dip switches set to the
far right.
2. Recheck the wiring to the ABCD connections.
Evolutionr Connext wall control can find zones 5 - - 8, but not
1 - - 4:
1. Make sure zone module 1 - - 4 has the dip switches set to the
far left.
2. Recheck the wiring to the ABCD connections.
Some zones do not provide enough comfort (a noticeable
difference exists between the actual room temperature and
operating set point, or equipment does not turn on):
— The zone airflow limit may be set too low. Perform the
zone airflow limit checkout procedure. See the
Evolutionr
Connext
Instructions for details.
Some zones provide too much airflow and are noisy:
— The zone airflow limit may be set too high. Perform the
zone airflow limit checkout procedure. See the
Evolutionr
Connext
Instructions for details.
Zone dampers do not move:
1. Check the fuse located on the Evolutionr Damper Control.
If the fuse is failed, check the damper wiring and inspect for
shorts. No more than five damper motors should be con-
nected to a single damper output. The fuse should be re-
placed with an identical 3A automotive type.
2. Use the System Checkout procedure (refer to the Installa-
tion Instructions) to test the zoning dampers and to verify
that the correct set of dampers is opening for each zone.
3. Dampers may be powered directly—for testing purposes
only—by connecting 24VAC directly across Com and
Open, or Com and Close. The damper should open or
close, based on which input is being powered. This will
rule out the damper.
