ComfortID™ Controls Start-Up
GENERAL — Air volume delivery to the conditioned space
is controlled by the modulating of the primary air damper and
the sequencing of the air source supply fan. The controller po-
sitions the damper by way of an actuator and turns the fan on
and off through linkage for the CCN compatible air source
equipment control.
PRIMARY SYSTEM CHECK
1. Check that all controls, control box, and ductwork have
been properly installed and set according to installation
instructions and job requirements.
2. Check that final filters have been installed in the air-
handling apparatus. Dust and debris can adversely affect
system operation.
3. Check fan and system controls for proper operation.
4. Check electrical system connections.
5. Check that all air duct connections are tight.
6. See that all balancing dampers at box outlets are in full-
open position.
ComfortID CONTROL SYSTEM CHECK
1. Check interconnections between thermostats and unit
controls.
2. Force all dampers to control to the maximum cooling cfm
using the Building Supervisor, ComfortWORKS
®
,
Network Service Tool or ComfortID Test and Balance
Tool software.
3. Set supply-duct balancing dampers, if used, in maximum
cool position.
4. Check that the static pressure available at each box is
above the minimum required, force all dampers to control
to the minimum cooling cfm and verify that the static
pressure is below the maximum safe operating limits
when the damper is providing minimum cooling airflow.
5. Set air source supply fan speed and duct static pressure
regulator to obtain satisfactory static pressure at design
airflow.
6. While at peak system load, check system operation and
pressures.
7. Check duct pressure at various points in the system. If sys-
tem static pressure probe has been properly located, pres-
sure at last units of all branch headers should remain essen-
tially the same. If pressure has changed considerably, re-
check the supply air static pressure controller or relocate
the probe to better sense system pressure changes.
8. Remove all forces and balance each control box zone
using through the balancing procedure described on
page 9.
