APOGEE BACnet Schedule Optimization Editor

For related procedures, see the step-by-step section.

NOTE: The system assumes that all command objects in the list are homogenous, so it checks only the first command object in the list for SSTO optimization criteria.

The Optimization (SSTO) tab displays a list of the following expanders from which you can configure Start/Stop Time Optimization (SSTO) for a BACnet schedule:

• Settings: Specify unit of measurement for optimization.
• General. Specify the information necessary for start and stop optimization, and heating operation calculations. The values or points provided in the Temperatures, Heating Setpoints, and Cooling Setpoints sections are used by SSTO in calculations to determine optimal start and stop times for heating and cooling. To complete the General expander, you must:
• specify the type of operation you want to implement for the schedule optimization.
• define the allowed and desired operations (heating only, cooling only, heating and cooling, none).
• specify a point name or value for the outside and zone temperatures.
• define the heating and cooling setpoints during occupancy and vacancy.
• Start. Specify start optimization parameters for heating and cooling. To complete the Start expander, you must:
• identify the schedule mode to start heating and cooling.
• select the actions SSTO takes if the heating or cooling setpoints are reached too early or late.
• select the algorithm SSTO uses to calculate start optimization.
• enable or disable learning.
• Stop. Specify stop optimization parameters for heating and cooling. To complete the Stop section, you must:
• identify the schedule mode to stop heating and cooling.
• define the maximum stop duration, calculation constant, and tolerated deviation.
• enable or disable learning.
• Night. Set the heating and cooling modes and the allowed temperature differential for night operation.

Validation for BACnet Schedule Optimization

Validation helps protect against inadvertent changes that may affect the system. This means that user action might be required for changing validated BACnet schedule objects on an APOGEE BACnet network. The action required, depends on the validation profile of the selected BACnet schedule. This means when editing the configuration, to be able to save the changes, the user will be asked to provide a comment (Validation Profile = Enabled), a comment and a password (Validation Profile = Supervised). In addition, you might be required Four eyes validation (supervisor user name and password).

Details of the validation action are recorded and stored in the Detail Log tab.
