6. Secure mounting plastic to wall using two screws and
anchors provided.
7. Adjust length and routing of each wire to reach each wire
entry on the connector backplate. Strip ¼ inch of insulation
from each wire.
8. Match and connect thermostat wires to proper terminals on
User Interface backplate. See wiring diagram figures 12, 13
and 14.

B — Yellow = Data B
C — White = 24VAC (Com)
D — Red = 24VAC (Hot)
NOTE:
It is not mandatory that the above color code be used, but
each ABCD connection in the system MUST be wired consis-
tently. A separate ABCD Connector comes inside packaging and
should be used when connecting to the furnace (or fan coil). (See
Fig. 10)
NOTE:
Insert connector properly into circuit board.
CAUTION:
ELECTRICAL OPERATION HAZARD
Failure to follow this caution will result in equipment
damage or improper operation.
Improper wiring of the ABCD connector will cause the
Evolution Control™ to operate improperly. Check to
make sure all wiring is correct before proceeding with
installation or turning on power.
9. Push any excess wire into the wall. Seal hole in wall to
prevent 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.
humidifier, ventilator, UV lights, etc.)
12. Turn on power to equipment.
EQUIPMENT WIRING DIAGRAMS:
See wiring diagram Figs. 12, 13 and 14.
NOTE:
For other applications not listed, refer to the Network
Interface Module (NIM) Installation Instructions.
See wiring diagram figure 12 for a Typical Four-Wire Connection
Diagram, which includes an Evolution indoor communicating
furnace or FE fan coil with a 2-speed Puron® communicating
outdoor unit. No additional OAT (outdoor air temperature) sensor
is required because the Evolution Control will use the temperature
sensor inside the 2-speed unit.
See wiring diagram figure 13 for a Typical Connection Diagram,
which includes a variable-speed indoor communicating furnace or
FE fan coil, with a 1-speed air conditioning unit (non-
communicating outdoor). An Outdoor Air Temperature sensor
may be installed (not required) at the indoor furnace or fan coil
OAT terminals. When OAT is applied, the Evolution System will
provide full system features and benefits.
See wiring diagram Fig. 14 for a Typical Connection Diagram for
FE fan coil with a 1-speed heat pump (using non-communicating
outdoor unit). When OAT is applied, the Evolution System will
provide full system features and benenfits.
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 System
control humidifier operation.
Bypass Humidifiers — A bypass humidifier should be wired
directly to the furnace or fan coil HUM and 24vac COM terminals.
The Evolution Control will automatically energize the HUM
output during a call for humidification.
Fan Powered Humidifiers — Most fan powered humidifiers
produce internal 24vac in order to energize upon a switch or
contact closure. For this application, a 24vac N.O. Isolation Relay
(DPST) MUST be used to prevent mixing the internal humidifier
power with the indoor equipment transformer. Applying 24vac
isolation relay coil to furnace or fan coil HUM and COM terminals
will allow the Evolution Control to automatically energize the
HUM output during a call for humidification. The N.O. relay
contacts will be used to energize the humidifier. See fan powered
humidifier installation instructions for more details.
