Performing system checkout
1
Verify that all power and communication connections are correct and tight.
2
Verify that all zone terminals, ductwork, and zone controllers are properly installed and set according to
installation instructions and job requirements.
3
Verify that all air duct connections are tight.
4
Verify that zone terminal fans and system controls operate properly. Verify that actuator screws are properly
tightened.
5
At the zone terminals, check electrical system and connections of any optional electric reheat coil. If hot
water reheat is used, check piping and valves against job drawings.
6
Verify that all zone terminal dampers are fully open.
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
Verify that the air source motor starter and, if applicable, the Hand/Off/Auto (HOA) switch are installed and
wired.
9
Verify that the area around the air source is clear of construction dirt and debris.
10
Verify that final filters are installed in the air handler(s). Dust and debris can adversely affect system
operation.
11
Verify that the space sensor and all optional sensors are reading correctly.
NOTE
You must use the i-Vu® application or Field Assistant to configure ZS Sensors.
CAUTION
Before starting the air source fan, make sure the zone terminal dampers are not closed. Starting
the fan with dampers closed will damage the system ductwork.
