General
The General expander is where you provide the information necessary for start and stop optimization, and heating operation calculation. The information provided in the Temperatures, Heating Set Points, and Cooling Set Points sections are used by SSTO in calculations to determine optimal start and stop times for heating and cooling.
For some fields, the following buttons display:
Button | Description |
| The Data Point button allows you to enter a point in the field. Drag-and-drop the point from System Browser. |
| The Number button allows you to enter a number in the field. |
Operation
Item | Description |
Start Optimization Stop Optimization Night Operation Virtual Start/Stop | These boxes specify whether that type of optimization or operation is enabled or not. If a box is checked, the optimization is enabled. You can check more than one box. If no boxes are checked, SSTO is disabled. The Virtual Start/Stop option disables Start Optimization, Stop Optimization, and Night Operation. You can then only view data for these sections. Virtual Start/Stop is disabled when any of the other boxes are checked. |
Allowed Operation | Specifies the type of schedule operation that can take place. You can check one or both of the following:
It is recommended that you enable both Heating and Cooling, even if there is heating only or cooling only, since this allows for any future changes in the specifications. If neither are selected, SSTO is disabled. |
Desired Operation | Specifies the operation that is allowed at a given time (Seasonal). It is recommended that you enter a season point whose value represents the allowed operation (heating only in winter or cooling only in summer) at a given time. > Click the > Click the |
Temperatures
Item | Description |
Outside Temperature | The point name that stores the outside air temperature. The outside air temperature and the zone temperature are used to calculate the start and stop times. It is recommended that you enter an outside air temperature sensor point in this field. > Click the > Click the |
Zone Temperature | The point name or value of the current temperature of the zone. The outside air temperature and the zone temperature are used to:
It is recommended that you enter a zone temperature sensor point in this field. If you type a value in the Zone Temperature field, SSTO calculates the start and stop times without the zone temperature. Therefore, the start and stop calculations may not be as accurate as with a zone temperature sensor point. You can do one of the following: > Click the > Click the |
Heating Set Points
Item | Description |
During Occupancy | Defines the heating setpoint to which SSTO warms the zone. SSTO uses these values to:
NOTE: An early start of heating will NOT occur if the Zone Temperature is above the During Occupancy parameter. This is true for all Time Shift options. It is recommended that you type a setpoint value in this field. You can do one of the following: > Click the > Click the |
During Vacancy | Defines the heating setpoint to which SSTO warms the zone while in Vacant (VAC) mode. You only need to complete this field if you checked the Night Operation box. It is recommended that you type a setpoint value in this field. You can do one of the following: > Click the > Click the |
Cooling Set Points
Item | Description |
During Occupancy | Defines the cooling setpoint to which SSTO cools the zone. SSTO uses these values to:
It is recommended you type a setpoint value in this field. You can do one of the following: > Click the > Click the |
During Vacancy | Defines the cooling setpoint while the zone is in Vacant (VAC) mode. You only need to complete this field if you check the Night Operation box. It is recommended that you type a setpoint value in this field. You can do one of the following: > Click the > Click the |
