INTELLIZONE2 BACNET INSTALLATION MANUAL
Safety Considerations
Installing and servicing heating and air conditioning
equipment can be hazardous due to system electrical
components. Only trained and qualified 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
BACnet 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 4 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 airflow.
• 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.
General Installation Information
Installation and Design Steps
1. Decide which areas of a building or office 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 flow and zone size settings
using IntelliZone2 BACnet 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 zone sensors.
8. Install the unit and the IntelliZone2 BACnet Comfort
Zoning system.
IntelliZone2 BACnet Control Panel
Locate the IntelliZone2 BACnet 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 BACnet 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 BACnet 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 BACnet Relay Panel to be mounted
indoors.
