| TRUE | 1 |
|
|
|
|
|
|
|
|
| nviWSHPEnable. The states for nviWSHPEnable are as follows: If |

|
|
|
|
|
|
|
|
| nviWSHPEnable.state is SW_OFF and the nviWSHPEnable.value is 0, |
|
|

|
|
|
|
|
|
| then WSHPEnable is 0 (Disable Water Source Heat Pump). If |
|
|
|
|
|
|
|
|
|
|
|
|
|
| nviWSHPEnable.state is SW_ON and the nviWSHPEnable.value is 0, then |
|
|
|
|
|
|
|
|
|
|
|
|
|
| WSHPEnable is 0 (Disable Water Source Heat Pump). If |

|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
| nviWSHPEnable.state is SW_NUL and the nviWSHPEnable.value is any |
|
|
|

|
|
|
|
|
|

|
|
| operator terminal, used in a trend log, or used in a control process. The |

|

| siSpaceTempS7: siSpaceTempS7 is the space temperature used by the |
| (nvoCtlDataG2) |
| 40 to 100 |
|
|
|
|
|
|
|
|
|
| control process and is read from another node via nviSpaceTemp or a local |
|
|
| Degrees C |
|
|
|
|
|
|
|
|
|
| sensor via nvoIO.siSpaceTempS7 or nvoIO.siReturnTempS7. If the network |
|
|
| (4 to 38) |
|
|
|
|
|
|
|
|
|
| input is not SI_INVALID, then the network input has priority. The local |
|
|

| nciConfig.ControlUsesRtnAirTemp is 0, then the space temperature sensor |
|
|
|
|
|
|
|
|
|
|
|
|
|
| is selected. When nciConfig.ControlUsesRtnAirTemp is 1, then the return |
|
|
|
|
|
|
|
|
|
|
|
|
|
| temperature sensor is selected. If the network input and the selected local |
|
|

|
|
|

|
|
|
|
|
|
| sensor has failed or are not configured, siSpaceTempS7 is SI_INVALID. |
