5. Drill two 3/16--in (4.8 mm) mounting holes in wall where
marked.
6. Secure mounting plastic to wall using two screws and an-
chors provided.
7. Adjust length and routing of each wire to reach each wire
entry on the connector backplate. Strip 1/4--in (6.4 mm) of
insulation from each wire.
8. Match and connect thermostat wires to proper terminals on
User Interface backplate. See wiring diagram Fig. 8, 9, and
10.

NOTE
: It is not mandatory that the above color code be used, but
each ABCD connection in the system MUST be wired consistently.
A separate ABCD Connector comes inside packaging and should
be used when connecting to furnace (or fan coil). Ensure connector
is inserted properly into circuit board. (See Fig. 11.)

ELECTRICAL OPERATION HAZARD
Failure to follow this caution may result in equipment damage
or improper operation.
Improper wiring of the ABCD connector will cause the
Evolution System to operate improperly. Check to make sure
all wiring is correct before proceeding with installation or
turning on power.
CAUTION
!
9. Push any excess wire into the wall. Seal hole in wall to pre-
vent any air leaks. Leaks can affect operation.
10. Attach Evolution Control to the mounting plastic by lining
up the plastic guides on the back of the control with the
opening on the mounting plastic and push on.
11. Perform installation of all other system equipment (i.e.
dampers, humidifier, ventilator, UV lights, etc.).
12. Turn on power to equipment.
See wiring diagram, Fig. 8, which includes an indoor
communicating furnace or FE fan coil, with a communicating
outdoor unit. No additional OAT (outdoor air temperature) sensor
is required because the Evolution Control will use the temperature
sensor inside the outdoor unit.
See wiring diagram, Fig. 9, for connecting an indoor
communicating furnace or FE fan coil with a 1--stage air
conditioning unit (non--communicating outdoor). An Outdoor Air
Temperature (OAT) sensor may be installed (but is not required) at
the indoor furnace or fan coil OAT terminals. When OAT sensor is
applied, the Evolution System will provide enhanced system
features and benefits.
See wiring diagram, Fig. 10, for connecting an FE fan coil with a
1--stage heat pump (non--communicating outdoor unit). When
OAT is applied, the Evolution System will provide enhanced
system features and benefits.
In a hybrid heat installation with a non--communicating heat pump,
an OAT sensor must be installed or the heat pump will not run.
NOTE
: For other applications not listed, refer to the Network
Interface Module (NIM) Installation Instructions.
Humidifier Connection
A 24VAC bypass or fan powered humidifier may be installed.
NOTE
:
Do Not Use
a traditional humidistat to control humidifier
operation. If a humidifier is installed, let the Evolution Control
operate humidifier.
Bypass Humidifiers
A bypass humidifier should be wired directly to the furnace or fan
coil HUM and 24VAC COM terminals. The Evolution Control will
