Functional Performance Test Checklist - VAV Terminals
The Contracting officer will select VAV terminals to be spot-checked during
the functional performance test. The number of terminals shall not exceed
[2] [10] [10 percent].
1. Functional Performance Test: Contractor shall demonstrate operation of
selected VAV boxes as per specifications including the following:
a.
Cooling only VAV boxes:
(1) Verify VAV box response to room temperature set point
adjustment. Turn thermostat to 5 degrees F above ambient and measure maximum
air flow. Turn thermostat to 5 degrees F below ambient and measure minimum
air flow.
