INTELLIZONE2
● 24V 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
● 24V
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 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
1.
Decide which areas of a home or offi ce will comprise
each of the individual zones. A maximum of four
individual zones with dual capacity (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.

● 24V Comfort
Zoning system.
Zone Control Panels
Locate the IntelliZone2 and IntelliZone2
● 24V panels 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 and
IntelliZone2
● 24V is not approved for outdoor installation
and, therefore, must be installed inside the structure being
conditioned. Do not locate the control panels in areas
where ambient conditions are not maintained within 45°F
to 95°F and are greater than 75% relative humidity. The
IntelliZone2 and IntelliZone2
● 24V control panels should
be mounted on or as close to the unit as possible by using
the mounting hardware provided. See Figure 1 for mounting
hole locations.
