vykonPro-OptStartStop

The OptStartStop component allows you to use Start Time Optimization and Stop Time Optimization to save energy. This component uses a space temperature input and area characteristics to calculate an optimal amount of lead-time before a scheduled event. It can analyze area temperature changes and adjust the optimization parameters based on the actual temperature change rates after an optimized start or stop.

The OptStartStop component is available in the vykonPro energy folder.

The two basic optimization types are described, as follows:

See the following sections for additional details:

OptStartStop operation

The OptStartStop calculation is performed at 15 seconds after the beginning of every minute, when the appropriate Start Enable or Stop Enable properties are set to true, a valid schedule event is linked to the component, and the next scheduled event value is not already set

NoteFor example, if a value is scheduled to be set to "true" in 1 hour but is already set to "true", no calculation is performed, even if the Start Enable or Stop Enable properties are set to "true".

The product of this calculation is the "Calculated Start Time" and the "Calculated Stop Time". The "Calculated Start Time" defines an early start command to achieve a specified temperature range by occupancy time. The "Calculated Stop Time" defines an early stop command without sacrificing the temperature range by unoccupancy time. After an optimized event is invoked, the actual area response (temperature change rate) is analyzed and weighted adjustments are made to the calculation parameters based on the detected values so that subsequent calculations might be more accurate.

Start time and stop time operations are described below:
