INTELLIZONE2 INSTALLATION MANUAL
Safety Considerations
Installing and servicing heating and air conditioning
equipment can be hazardous due to system electrical
components. Only trained and qualifi ed service personnel
should install, repair or service heating and air conditioning
equipment. When working on equipment, observe
precautions in the literature, tags and labels attached to the
unit, and other safety precautions that may apply. Follow all
safety codes. Wear safety glasses and work gloves.
WARNING: Before performing service or
maintenance operations on the system, turn
off main power switches to the indoor unit.
Turn off accessory heater power switch if
applicable. Electrical shock could cause
serious personal injury.
Delivery Information
When the equipment is received, all items should be
carefully checked against the bill of lading to be sure
all crates and cartons have been received. Examine the
contents for shipping damage, removing them from the
cartons if necessary. If any damage is noted, the carrier
should make the proper notation on the delivery receipt,
acknowledging the damage.
General rules to follow when installing a zone
system:
CAUTION: When installing the IntelliZone2 in
a structure with fossil fuel (oil, gas, propane)
appliances, it is important that both supply and
return dampers are used in each zone to avoid
potential back-drafting of fossil-fueled appliances.
•
Up to six zones on variable speed, up to four zones
with dual capacity units (two with single-speed units).
•
All dampers should be located as close to the main
trunk as possible to limit the amount of pressurized
trunk line and thus limit air leakage.
•
No less than three branch runs in a zone to prevent
a single branch obstruction (curtains or clothes etc.)
from affecting unit airfl ow.
•
Insulate and seal around rectangular dampers to
prevent leakage.
•
All dampers must be wired with 18-gauge wire.
NOTE:
Crimp connections should never be used on
solid conductor wire.
•
Ensure that the transformer can handle the power
requirements of the system.
•
No more than three dampers per zone.
•
Ductboard-mounted dampers should be supported
within six inches of the damper due to the weight and
stress on the ductboard.
General Installation Information
Installation and Design Steps
The IntelliZone2 Comfort Zoning system is to be used
only with heat pumps/air handlers equipped with Aurora
AXB or AHB controls. If the heat pump/air handler does
not have Aurora AXB or AHB controls you must use the
IntelliZone2•24V Comfort Zoning system.
1.
Decide which areas of a home or offi ce will comprise
each of the individual zones. A maximum of six
individual zones (four with dual capacity and two with
single-speed equipment) can be chosen.
2.
Calculate loads using software or other
recognized methodology.
3.
Use software to determine the equipment size and
performance based on the total heating and cooling
demands of the building, not the sum of the individual
zone demands.
4.
Find the peak heating and cooling demands and the
peak cfm required for each of the zones.
5.
Determine zone design air fl ow and zone size settings
using IntelliZone2 Design software.
6.
Lay out and size the supply air ductwork and dampers.
Care should be taken to avoid under sizing either the
supply air systems, return air systems, or diffusers.
7.
Decide where to locate the thermostats.
8.
Install the unit and the IntelliZone2 Comfort
Zoning system.
IntelliZone2 Control Panel
Locate the IntelliZone2 panel in an indoor area that
has enough space for service personnel to perform
maintenance or repair. Provide sufficient room to make
electrical connection(s). The IntelliZone2 is not approved
for outdoor installation and, therefore, must be installed
inside the structure being conditioned. Do not locate the
control panel in areas where ambient conditions are not
maintained within 45°F to 95°F and are greater than 75%
relative humidity. The IntelliZone2 control panel should be
mounted on or as close to the unit as possible by using the
sheet metal screws provided. See Figure 1 for mounting
hole locations.
NOTE:
IntelliZone2 Relay Panel to be mounted indoors.

NOTE:
Use longer screws (not provided) to penetrate
through drywall into stud.
