Input Points
| Name | Point Template | Positional Requirements | Optionality | Multiplicity |
|---|---|---|---|---|
| Outside Air Temperature | OaTemp | This point must be a direct child of the equipment that the rule is attached to. | Mandatory | Scalar |

Input Constants
| Name | Data Type | Default Value | Description |
|---|---|---|---|
| Delay | Numeric | 360 | The delay represents a span of time in minutes during which the sensor must be in a fault state before the rule starts to actually report that it is in a fault state. The intent of the delay is to reduce the level of alert noise by ensuring that the system does not alert until the fault condition has been in effect for some minimal interval of time. |
| Temperature Sensor Threshold | Numeric | 5 | This number (in Fahrenheit) is the temperature sensor threshold. The difference value of the on-premise temperature and off-premise temperature must exceed the temperature sensor threshold for a period longer than the delay in order for a fault condition to exist. |
