Availability Determination Common Attributes

DEVICE-AVAILABLE, CLG-AVAILABLE, HTG-AVAILABLE, PH-AVAILABLE, RH-AVAILABLE, ZNHTG-AVAILABLE (State)

G, V

Displays True when the device is available and False when the device is not available

 

isAvailable

 

Network input for enabling or disabling a device.

True

OA Temperature

 

Contains the temperature that is compared to the outdoor air temperature setpoint to determine if heating or cooling is available.

21 °C, 70 °F

OA Temperature Diff

 

Contains the differential input to the comparison between the OA temperature and the OA temperature enable setpoint. When Heating/Cooling = Cooling, a greater than comparison is used. When Heating/Cooling = Heating, a less than comparison is used.

2 °C, 4 °F

OA Temperature Enable Setpoint

 

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

16 °C, 61 °F

Resolution Mode

 

Allows the module to be configured to use the outdoor air temperature, the network input, or either of the two to enable a cooling or heating device

Either Can Activate

Set Name: Resolution Mode

Cooling Availability Determination-Specific Attributes

HeatingCooling

 

Specifies that when Heating/Cooling = Cooling, a greater than comparison is used, so State is True if the OA Temperature is greater than the OA Temperature Setpoint.

Cooling

Set Name: Heating/Cooling

Heating Availability Determination-Specific Attributes

HeatingCooling

 

Specifies that when Heating/Cooling = Heating, a less than comparison is used, so State is True if the OA Temperature is less than the OA Temperature Setpoint.

Heating

Set Name: Heating/Cooling

Preheat Availability Determination-Specific Attributes

HeatingCooling

 

Specifies that when Heating/Cooling = Heating, a less than comparison is used, so State is True if the OA Temperature is less than the OA Temperature Setpoint.

Heating

Set Name: Heating/Cooling

Reheat Availability Determination-Specific Attributes

HeatingCooling

 

Specifies that when Heating/Cooling = Heating, a less than comparison is used, so State is True if the OA Temperature is less than the OA Temperature Setpoint.

Heating

Set Name: Heating/Cooling

Zone Heating Availability Determination-Specific Attributes

HeatingCooling

 

Specifies that when Heating/Cooling = Heating, a less than comparison is used, so State is True if the OA Temperature is less than the OA Temperature Setpoint.

Heating

Set Name: Heating/Cooling

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