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.
EQUIPMENT HAZARD
Failure to follow this caution may result in equipment damage.
Do not apply 24VAC fan powered humidifier (with internal
power supply) direct to indoor unit HUM and COM terminals.

Power Up Sequence
This section addresses initial power up (or commissioning) of a
new Infinity Zone Control. The User Interface will communicate
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--stage Air Conditioner / Heat Pump (including
Hybrid Heat).
The User Interface display will light up and indicate that it is now
“ESTABLISHING COMMUNICATIONS WITH EQUIPMENT
PLEASE WAIT”. The User Interface will automatically continue
by
“SEARCHING
FOR
EQUIPMENT”,
followed
by
“SEARCHING FOR OUTDOOR EQUIPMENT” (See Fig. 16).
Once the indoor and outdoor equipment has been found, the
Installer will be asked to select Accessories. Packaged Products
will be automatically identified and the Installer will be asked to
select Accessories. Proceed to Selecting Accessories.

NOTE
: If the variable--speed indoor equipment (furnace or fan
coil) cannot be found, the User Interface will display “CANNOT
COMMUNICATE WITH INDOOR UNIT”. This MUST be
corrected before the initial power up sequence can continue. If
indoor unit is found, but outdoor unit is not found, “OUTDOOR
UNIT NOT IDENTIFIED” will appear. Proceed to the next section
for Outdoor Unit Identification.
Selecting Outdoor Unit
If there is no communicating outdoor unit, the screen, shown in
Fig. 17, will appear. Press either Left or Right Up/Down button to
select AC (air conditioner), HP (heat pump), or None (no unit
installed). Press right--side button to continue to next screen.

Fig. 17 -- Selecting Outdoor Unit
If either AC or HP has been selected as the outdoor unit type, the
middle screen will appear (See Fig. 17). Press either Left or Right
Up/Down button to select appropriate Btu size of outdoor unit,
then press right side button to continue. If a NIM (Network
Interface Module) is applied for non--communicating two--stage
outdoor equipment, select 1 or 2--stage compressor operation, and
press right--side button to continue.
NOTE
: Range of outdoor unit Btu selection is limited by model
number of indoor unit installed. The Infinity Zone Control will not
allow an outdoor unit size that is not supported by the installed
indoor unit.
NOTE
: On new system installations, the model and serial number
will be recognized and displayed. On any indoor/outdoor board
replacements, the equipment will be recognized but the exact
model/serial number will not be displayed.
Selecting Indoor Evaporator Coil
If a furnace is installed with a variable capacity heat pump, a screen
will appear to select the installed indoor evaporator coil. This
selection is used to adequately calculate refrigerant charge required
while in the Heat Pump Charging screens under the Heat Pump
Checkout menu. Select “other” for non--Carrier evaporators.
Selecting Electric Heater
If the equipment is a fan coil, packaged heat pump, or packaged
AC and the electric heater is not self--identifying, “ELECTRIC
HEATER NOT IDENTIFIED” will appear (See Fig. 18). Press
either Left or Right Up/Down button to select appropriate size of
electric heater installed, then press right--side button to continue.
An asterisks (*) will appear next to electric heater sizes that may
cause excessive airflow.
