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 Control to the mounting plastic by lining up
the plastic guides on the back of the control with the open-
ing 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. 12, 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 Infinity Control will use the temperature
sensor inside the outdoor unit.
See wiring diagram, Fig. 13, 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.
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.

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 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 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
