formance tests.
B. The tests described in this section are to be performed in addition to the tests that the
Contractor performs as a necessary part of the installation, startup, and debugging process.
Control system testing shall be coordinated with the HVAC Shop.
C. The Contractor shall provide at least two men equipped with two-way communication, and
shall demonstrate actual field operation of each control and sensing point for all modes of
operation including day, night, summer, winter, occupied, unoccupied, fire/smoke alarm,
and power failure modes. The purpose is to test the setup, calibration, response, and action
of every point. Any test equipment required to prove the proper operation shall be
provided by and operated by the Contractor. The Commissioning agent and the Owner's
representative shall observe, direct and review these tests on site at controller panel / field
location.
1. The system software shall be complete such that each control loop shall function as
specified in the Sequence of Operation and proper PID tuning. This Subcontractor
shall be required to furnish the software program and test the operation of every
control loop.
2. After all field connections have been made and control power is available in the
control panel, the Owner's representative shall be notified and the control system shall
be energized. Any required reloading of the software shall be performed and
commissioning of the mechanical system, automatic temperature control system, and
other connected systems shall commence.
3. This Subcontractor shall be responsible for all necessary revisions to the software as
required to provide a complete and workable system consistent with the letter and
intent of the specification. Control performance criteria is specified in the sequence of
operations shown on the drawings and/or the specifications.
D. Operational logs for each system which indicate all setpoints, operating points,
valve/damper positions, mode, and equipment status shall be submitted to the Archi-
tect/Engineer. These logs shall cover a 24-hour period and have a sample frequency of not
more than 10 minutes. The logs shall be provided in printed and digital media formats.
E. Control loops shall maintain setpoint within the following tolerances:
Air Pressure
0.5" w.g. range 0-6" w.g.
0.01" w.g. range -0.1 to 0.1" w.g.
Airflow
100 cfm
Temperature
1.0°F
Humidity
5% RH
Fluid Pressure
2.0 psi range 1-150 psi
2.0" w.g. range 0-50" differential pressure
Control loops that do not meet the above tolerances shall be re-tuned.
