START-UP
Use the Carrier network communication software to start up
and configure the zone controller.
All set-up and set point configurations are factory-set and
field-adjustable.
Changes can be made using the System Pilot or Carrier soft-
ware. During start-up, the Carrier software can also be used to
verify communication with each zone controller.
For specific operating instructions, refer to the literature
provided with the software.
Perform System Checkout
1. Check correctness and tightness of all power and commu-
nication connections.
2. Check that all air terminals, ductwork, and zone control-
lers are properly installed and set according to installation
instructions and job requirements.
3. Check that all air duct connections are tight.
4. At the air terminals, check fan and system controls for
proper operation. Verify that actuator screws are properly
tightened.
5. At the air terminals, check electrical system and connec-
tions of any optional electric reheat coil. If hot water re-
heat is used, check piping and valves against job draw-
ings.
6. At the air terminals, make sure that all balancing dampers
at box outlets are in the fully open position.
7. If using an air source with field-installed controls, make
sure controls and sensors have been installed and wired
per manufacturer installation instructions.
8. At air source, verify that the motor starter and, if applica-
ble, the Hand/Off/Auto (HOA) switch are installed and
wired.
