kitControl-OutsideAirOptimization

This component supports applications that need to allow for enthalpy based free cooling. This object is typically used during occupancy periods.

OutsideAirOptimization is available in the Energy folder kitControl palette.

The freeCooling output is set to false if outside >= inside and set to true if outside <= inside - (abs) thresholdSpan.

There is also a low temperature check to protect against freezing.

Property	Value	Description
Temperature Facets	Config Facets window	Selects units and configures how the value displays: `units` defaults to temperature. `precision` defines the number of decimal places of temperature. `min` defines the lowest temperature allowed. `max` defines the highest temperature allowed. This configuration applies to `Outside Temp`, `Inside Temp`, and `Low Temperature Limit` properties.
Humidity Facets	Config Facets window	Selects units and configures how the value displays: `units` defaults to percentage of relative humidity (%RH). `precision` defines the number of decimal places of humidity percentage. `min` defines the lowest humidity allowed. `max` defines the highest humidity allowed. This configuration applies to the `Outside Humidity` and `Inside Humidity` property values.
Outside Temp	number of degrees of temperature (defaults to 0.0 degrees F) and null definition	Defines the current outside air temperature. This input must be valid for this object to function. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Outside Humidity	percentage of humidity (defaults to 0.0 RH percent) and null definition	Defines the current outside air humidity. This input must be valid for this object to function. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Inside Temp	number of degrees of temperature (defaults to 0.0 degrees F) and null definition	Defines the current inside air temperature. This input must be valid for this object to functio
Inside Humidity	percentage of humidity (defaults to 0.0 RH percent) and null definition	Defines the current inside air humidity. This input must be valid for this object to function.
Low Temperature Limit	number of degrees of temperature (defaults to 0.0 degrees F) and null definition	Provides freeze protection. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Outside Enthalpy	number (defaults to 0.00) and null definition	Displays the calculated outside air enthalpy. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Outside Enthalpy String	text (defaults to blank) and null definition	Provides the outside enthalpy value as a string or possible status/error message. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Inside Enthalpy	number (defaults to 0.00) and null definition	Displays the calculated inside air enthalpy. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Inside Enthalpy String	text (defaults to blank) and null definnition	Provides the inside enthalpy value as a string or possible status/error message. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Free Cooling	`true` or `false` (default) and null definition	Sets the value of the `Free Cooling Command` when the component determines that free cooling should be used. Otherwise, the value is null. When null value is checked, the value displayed defaults to the incoming value from the device. If you remove the check mark you can configure the `In` value.
Current Mode	text (defaults to No Free Cooling)	Indicates what mode this object is currently in: Input out of range Free Cooling No Free Cooling Low temperature Input error
Threshold Span	number to two decimal places (defaults to 1.00)	Configures the difference between the inside enthalpy and the outside enthalpy. The actual difference must be greater than this value before the system enables free cooling.
Use Enthalpy	`true` (default) or `false`	Enables (`true`) and disables (`false`) the use of enthalpy for determining if free cooling is available. Otherwise, the component uses outside and inside temperature to decide.
Free Cooling Command	`true` (default) or `false`	Defines the Boolean value to be set in the `Free Cooling` property if free cooling is available.
Use Null Output	`true` (default) or `false`	`true` sets the null flag on `Free Cooling` output when free cooling is not available.
