V. INSTALL BAROMETRIC BYPASS DAMPER
NOTE:
The barometric bypass damper is a critical part of Zone
Perfect Plus System for controlling noise at minimum airflow. A
barometric bypass should be installed unless the duct work and
indoor unit have been sized for use without a bypass.
The bypass should be installed according to local codes and
SMACNA standards. Be sure bypass is properly supported.
For proper installation, refer to Installation Instructions packaged
with barometric bypass.
CAUTION:
Failure to properly install leaving air tem-
perature sensor can cause permanent damage to the
HVAC equipment.
VI. INSTALL LEAVING AIR TEMPERATURE (LAT)
SENSOR
Locate LAT sensor in main supply trunk after heating and cooling
coil and before bypass damper and first branch. The LAT sensor is
radiant shielded to prevent heat from affecting correct air tempera-
ture.
1. Drill a 1/4-in. hole at location in supply trunk where sensor
will be installed.
2. Insert sensor in hole and use as a template to mark the 2
mounting holes.
3. Drill two 1/16-in. holes to accept No. 6 screws through
pre-drilled holes in duct temperature sensor back plate.
4. Use 2 No. 6 sheet metal screws to mount duct temperature
sensor to unit.
5. Connect sensor to 2-conductor wire using provided wire
nuts. (See Fig. 9, 10, or 11 for connection to Equipment
Controller.)
VII. INSTALL HEAT PUMP TEMPERATURE (HPT)
SENSOR
The HPT sensor is required in all heat pump/fan coil installations.
It is not used in dual fuel(heat pump/furnace installation). It
measures the temperature of the air leaving the indoor coil. The
sensor is to be installed downstream of the indoor coil but before
the electric heaters. It can be installed through the wall of the fan
coil or may be located entirely inside the fan coil near the blower
inlet. Anchor firmly in place with cable ties so that it cannot
interfere with the blower wheel. (See Fig. 9, 10, or 11 for
connection to Equipment Controller.)
VIII. FINAL WIRING
Bring all Equipment Controller wires together at Equipment
Controller. Make all connections as indicated on Fig. 9 (for 2-zone
installations), Fig. 10 (for up to 4-zone installations), or Fig. 11
(for up to 8-zone installations).
Figures 15 through 38 show the connection between the Equip-
ment Controller and the HVAC equipment. Select proper diagram
for your equipment and connect accordingly. This connection will
require as few as 4 or as many as 7 conductors. See Table 4 to
identify the correct wiring figure.
NOTE:
Table 4 and wiring diagrams appear in sequence near the
end of this document.
NOTE: It is good practice to mark each wire as the final
connection is made. This will preserve its identity if it is ever
disconnected.
