Table 1. System Enable Attributes

Name

Type 1

Description

Default Value

HeatingCooling

 

Determines the polarity of the comparison. Set HeatingCooling to Heating for a heating device, and set HeatingCooling to Cooling for a cooling device.If HeatingCooling is set to Cooling, a greater than comparison is used, so State is true if the OA Temperature is greater than the OA Temperature Setpoint.If HeatingCooling is set to Heating, a less than comparison is used, so State is true if the OA Temperature is less than the OA Temperature Setpoint.

Cooling

Set Name: Heating/Cooling

HWSYS-AVAILABLE or CHWSYS-AVAIL

 

Indicates if the State output is true when the device is available and is false when the device is not available.

False

Boolean

isAvailable

 

Enables or disables a device.

True

Boolean

OA Temperature

 

Indicates the outdoor air temperature.

24, 70

Display Units: °C, °F

OA Temperature Diff

 

Indicates the differential for the setpoint.

4

Display Units: °C, °F

OA Temperature Enable Setpoint

 

Indicates the outdoor air temperature setpoint above which, the cooling is enabled, or below which the heating is enabled.

15, 61

Display Units: °C, °F

Emergency Mode

 

Enables pumps to start when there is a frost event. This is an input connected to the State output of the Frost Protection Determination module.

Normal

Set Name: CP Frost Protect

1 C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and Commissioning Modes Only, V - Calculated Value (Outputs)
