kitControl-OptimizedStartStop
Start Time Optimization and Stop Time Optimization to save energy. It 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.
OptimizedStartStop component is available in the Energy folder of the kitControl palette.
Figure 47. OptimizedStartStop properties
| Property | Value | Description |
|---|---|---|
| Heat Cool Mode | drop-down list and null definition | Selects heating or cooling. The selected option applies only to optimized stop calculations. This means that optimized stop
calculations are performed only for the selected mode. Optimized start calculations are performed for both heat and cool modes
regardless of this property value.

or other possible messages. For example, the following message indicates that an optimized stop has occurred: Optimized stop for 14-Jun-07 5:18 PM EDT schedule time. Space temp is 75.0. When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you
can configure the |
| Upper Comfort Limit | degrees to two decimal places (defaults to 0.00) (defaults to 77.00 F, 25.00 C) | Defines the cooling mode target temperature. |
| Lower Comfort Limit | degrees to two decimal places (defaults to 0.00) (defaults to 68.00 F, 20.00 C) | Defines the heating mode target temperature. |
| Dynamic Parameter Adjust | true (default)or false |
Controls if calculation the component programmatically adjusts parameters after an execution. After the component completes
a start or stop control, if this property is set to true, the component evaluates the actual recovery rate (degrees/hour) and automatically adjusts the values of the runtime and
drifttime properties so that they are influenced by actual drift time and run time.
|
| Old Parameter Multiplier | single-digit number (defaults to 2) | Applies a weighting factor to the dynamic parameter adjustment calculation. This value affects how much weight to assign to the previous runtime property value when the component uses it in a dynamic parameter adjustment calculation. A larger value increases the weighting factor given to the previous runtime value, and a smaller value decreases this weighting factor. |
| Earliest Start Time | hours minutes seconds (defaults to 12 and 10 seconds AM EDT (Eastern Daylight Time)) | Specifies a time, before which, the component may issue no optimized start command. If this value is set earlier than the
Calculated Command Time, the component adjusts the Calculated Command Time to equal this time.
|
| Earliest Stop Time | hours minutes seconds (defaults to 4 PM EDT (Eastern Daylight Time)) | Specifies a time, before which, the component may issue no stop command. If this value is set earlier than the Calculated Command Time, the component adjusts the Calculated Command Time to equal this time.
|
| Drifttime Per Degree cooling User Defined | single-digit number to two decimal places (defaults to 0.00) | Sets a default value for calculating the rate of drift in cooling mode. The component copies this value to the Drifttime Per Degree Cooling property.
|
| DriftTime Per Degree Heating User Defined | single-digit number to two decimal places (defaults to 0.00) | Sets a default value for calculating the rate of drift in heating mode. The component copies this value to the Drifttime Per Degree Heating property.
|
| Runtime Per Degree cooling User Defined | single-digit number to two decimal places (defaults to 0.00) | Sets a default value for calculating the runtime value in cooling mode. The component copies this value to the Runtime Per Degree Cooling property.

adjusts this value if Dynamic Parameter Adjust value is set to true.
|
| Runtime Per Degree heating | two-digit number to two decimal places (defaults to 10.00) | Displays the actual value used to calculate an optimized start time when the equipment is in heating mode. The component automatically
adjusts this value if Dynamic Parameter Adjust value is set to true.
|
| Last Start Time | date, hours:minutes (defaults to 7 PM EST (Eastern Standard Time) | Displays the last start time used to calculate an optimized start time. Since the component allows only one optimized start per day, this value does not display start times (restarts) that occur subsequent to the initial start time for the day. |
| Last Stop Time | date, hours:minutes (defaults to 7 PM EST (Eastern Standard Time)) | Displays the last stop time used to calculate an optimized stop time. Since the component allows multiple optimized stops per day, this value changes to reflect the latest optimized stop time. |
| Outside Temp At Beginning | number of degrees (defaults to 0.00) and null definition | Displays the outside air temperature at the time of the last start or stop command. This is the temperature used in the dynamic
parameter adjustment calculations.
When null is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you
can configure the |
| Space Temp At Beginning | number of degrees (defaults to 0.00) and null definition | Displays the space temperature at the time of the last start or stop command. This is the temperature used in the dynamic
parameter adjustment calculations.
When null is checked, the corresponding value defines the default when a calculation returns null. |
| Calculated Command Time | hours:minutes (defaults to 7 PM EST (Eastern Standard Time)) | Shows the calculated time for the next command. This could be a start or a stop command. |
| Program Mode | read-only single-digit number (defaults to zero (0)) | Displays one of five current heating or cooling states for an optimized start or stop. These states serve primarily in logic
control and may also inform the system engineer.
0 (no calculation) indicates that no calculation is in progress. 1 (start calculation) indicates that the optimized start calculation is ongoing, but no optimized start or stop is yet in progress. 2 (start in process) indicates that the component initiated an optimized start. 3 (stop calculation) indicates that an optimized stop calculation is ongoing, but no optimized start or stop is yet in progress. 4 (stop in process) indicates that the component initiated an optimized stop. |
