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. 14 for connecting an Infinity FE fan coil
with a 1-speed 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 transformer. Applying 24vac
isolation relay coil to furnace or fan coil HUM and COM terminals
will allow the Infinity Zone 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.
FIRE OR EQUIPMENT HAZARD
Failure to follow this warning could result in equipment
damage or fire.
Do not apply 24vac fan powered humidifier (with internal
power supply) direct to indoor unit HUM and COM termi-
nals.

SECTION 1 — POWER UP SEQUENCE
This section addresses initial power up (or commissioning) of a
new Infinity Zone Control™. The User Interface will communi-
cate and identify all Infinity components in the system. The
following is a typical example for a communicating Variable-
Speed Furnace / Fan Coil with a 2-spd. Air Conditioner / Heat
Pump (including Dual Fuel).
The User Interface display will light up and indicate that it is now
