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. 14.)

CAUTION
!
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
Infinity Zone System 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 pre-
vent any air leaks. Leaks can affect operation.
10. Attach Infinity Zone Control to the mounting plastic by lin-
ing 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 diagrams Fig. 11, 12, and 13 for connecting the Infinity
Zone Control and Smart Sensors to the Damper Control Module.
More information regarding Damper Control set- -up and wiring
can be found in Damper Control Module Installation Instructions.
See wiring diagram, Fig. 11, which includes an indoor
communicating furnace or FE fan coil, with a 2- -stage Puron
refrigerant communicating outdoor unit. No additional OAT
(outdoor air temperature) sensor is required because the Infinity
Zone Control will use the temperature sensor inside the outdoor
unit.
See wiring diagram, Fig. 12, 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 Infinity 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.
See wiring diagram Fig. 13 for connecting an FE fan coil with a
1- -stage heat pump (non- -communicating outdoor unit). When
OAT is applied, the Infinity System will provide enhanced system
features and benefits.
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 Infinity Zone Control
operate humidifier.
Bypass Humidifiers
A bypass humidifier should be wired directly to the furnace or fan
coil HUM and 24VAC COM terminals. The Infinity Zone 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
