5. Preliminary ChecksThe following general check list must be done before starting the test:

1. Proper pneumatic pressures and conditions2. Proper electric voltage and amperages, and all circuits are free from grounds or faults.3. Integrity/safety of all electrical [and pneumatic] connections4. Proper interface with fire and life safety systems5. Identification of all necessary control settings determined from balancing procedures including: Optimum VAV duct pressure set points VAV fan VFD minimum and maximum speed settings VAV Return fan volume tracking settings Minimum outside air damper settings for air handling units. VAV box minimum and maximum volume settings. Optimum differential pressure set points for variable speed pumping. Variable volume pumps VFD minimum and maximum speed settings. Verification of air-handler maximum design flow.6. Testing, calibration, and setting of all digital and analog sensing and actuating devices.7. Checking and setting zero and span adjustments for all actuating devices.8. Checking of each digital control point.9. Programming and testing of all sequences of operation, schedules and set points.10. Proper tuning of all control loops.

6. Testing Procedure

6.1 Verification checks:Those full range of physical inspections and checks that are conducted to verify that specific components, equipment, systems, and interfaces between systems conform to a given criteria. These checks typically verify proper installation, start-up and initial contractor checkout, prior to equipment being functionally tested. Documentation checks: verify specifications, submittals, TAB report, pre-commissioning report, as-built drawings, and training implementation. Hardware/software installation checks: verify nameplate data, verify installed characteristics, and verify system is operational. Software implementation checks: verify AI, AO, DI/DO I/O points, verify sensor calibrations; demonstrate offline setpoints, control sequence logic, graphics, alarm codes and standard reports.

6.2 functional tests:Those full range of tests that are conducted to verify that specific components, equipment, systems, and interfaces between systems conform to a given criteria. These tests are typically used to verify that a sequence of operation is correctly implemented or that a design intent criterion has been met. They typically are done after equipment is placed in full operation. Performance tests, which include efficiency, capacity, load, monitoring and M&V or savings protocols, are considered a subset of functional tests. Software functionality tests. Operational trend tests: observed range of control; can be used to verify many control sequences. Control sequence tests. Possible tests include: start/stop (on/off); schedule (scheduled start/stop, optimum start/stop [includes warm-up and cool-down], unoccupied setback [includes night purge], sweep); lead/lag (includes runtime and equipment failure); staging; reset (including setpoint change, control by flow and speed control); safeties; economizer; life safety interface; power failure.

6.2 Networks (LAN/WAN):The media that connects multiple intelligent devices. LAN (local area network) implies a network over small geographic area. A building may have two LANs, one for the building computer network and one for the DDC system. WAN (wide area network) implies data transfer through a router. The most basic task of the network is to connect the DDC controllers so that information can be shared between them.

6.3 user interface devices:Operator workstation (desktop computer with necessary software to provide full access and operational capabilities to the entire DDC system); remote workstation, also known as a portable terminal (laptop computer with necessary software to provide full access and operational capabilities to the entire DDC system from a remote location); mobile terminal station, also known as a hand-held terminal (typically supplied and programmed by the vendor for specific set-up tasks); smart stats (thermostats that allow a multiple hierarchy of user entered offsets and adjustments); web browser (an internet based device with limited software that provides some level of access and operational capabilities).
