| true | Value of “Reliability” property is not NO_FAULT_DETECTED | |
| OVERRIDDEN | false | Always false |
| OUT_OF_SERVICE | false | “Present Value” and “Reliability” properties are not writeable via BACnet |
| true | “Present Value” and “Reliability” properties are writeable via BACnet |
Event State Property:
The following table describes the possible states of the “Event State” property:
| State | Reason |
| NORMAL (0) | Value of “Reliability” property is NO_FAULT_DETECTED |
| FAULT (1) | Value of “Reliability” property is not NO_FAULT_DETECTED |
Units Property:
The following table lists the possible units for each analog input object:
| Initial Value | Alternative 1 | Alternative 2 |

a.) Not an ASHRAE defined unit.
Reliability Property:
The following table describes the possible states of the “Reliability” property:
| State | Reason |
| NO_FAULT_DETECTED (0) | No fault detected |
| NO SENSOR (1) | Sensor is damaged or not connected |
COV Increment Property:
Default value is NaN (not a number). When the “COV Increment Property” is NaN or greater than 1000,000,000.0 then COV reporting is disabled.
MISCELLANEOUS INFORMATION
Reinitialize Device (RD):
The RD function is used to restart/ reboot the entire transmitter via BACnet. To use reinitialize device functionality a password is needed. The password is: “BACnet123”.
Device Communication Control (DCC):
The DCC functionality is used to stop initiating messages on the BACnet network. After receiving a DCC stop initiate message, the device does not respond to a request any more, except to RD or DCC requests. The use of the device communication control functionality is password protected. The password is: “BACnet123”.
Unsolicited COV Reporting:
When COV reporting is activated, a BACnet message is broadcasted every time when the difference between actual “Present Value” and the previous measured “Present Value” since last COV message exceeds the “COV Increment” value. Since no subscription list is supported, the COV message is always broadcasted. This function is useful for many BACnet clients which need the same information of one BACnet device (e.g. outdoor temperature)
