Chiller Plants: View and Control

Chiller plants are HVAC applications that regulate the operation of multiple chillers to provide a constant supply of chilled water at a specific temperature (setpoint). Chiller plants start and stop chillers as required by the chilled water demanded by the system and can also regulate the operation of the pumps that move the chilled water through the building.

In Tracer Ensemble, you can use the Chiller Plant page to view, set up data logs, and control chiller plants in the following ways:

• Manually rotate the chillers in the plant (Force Rotate). Normally the chillers rotate according to a specified interval.
• Manually put a chiller into service or take a chiller out of service (Force Add and Force Subtract).  Normally the number of chillers in service is configured to change based on chilled water demand.  You do not choose which chiller gets added or subtracted, because that is still determined by the chiller plant settings.
• Reassign the rotational order of the swing and numbered chillers.
• Make a chiller unavailable or available to the chiller plant (it must be a chiller that is already a member of the plant).
• Reset a chiller that has stopped due to a failure condition.  

Note: For more information about Trane chiller plant operations, consult the Tracer Summit programming and service documentation and engineering bulletins.

To view and control a chiller plant:

1. Go to Home | Building Name | Systems | Chiller Plant.  The Chiller Plants page appears.
2. Click on the name of the chiller plant you want to view.  The individual chiller plant status page appears, which is a list of the chillers in the plant.
3. Use the action buttons on the page to make changes to the chiller plant operation.
