BACNET DATA TABLES

BACnet Data Tables
CAUTION
Please note that each time a command is written to a configuration property,
(noted by a "cp" in front of the BACnet object name) the data is stored in
the unit controller's non-volatile or Flash memory. Writing to Flash memory
is an operation that has a finite limit. For this reason, the number of writes
made to BACnet objects linked to configuration properties must be limited
to avoid damage to the hardware.

Parameter is stored in FLASH/EEPROM (non-volatile memory) in either the communication module or in the unit controller . If Non-volatile Memory = Y, then the
1
value is saved through a power cycle . Writes to this parameter must be limited . If Non-volatile Memory = N, the value is not saved through a power cycle .
R = Read Only, W = Writeable, C = Commandable

3 A Null value is equal to 621.806ºF/327.67ºC. Its purpose is to indicate a sensor failure condition or when the unit controller is not using that particular temperature
value .

details . Also see BACnet PICS .
NOTE: Changing a temperature setpoint's minimum or
maximum value may result in an "Out of Range"
error . This is due to the internal Fahrenheit to Celsius
conversion . To prevent this error from occurring,
use an offset of 0.1º when writing to a minimum or
maximum temperature setpoint value .

installed and configured with a valid input.
Reflects the entering water temperature sensor value, if
R N
installed and configured with a valid input.
Reflects the discharge air temperature sensor value, if
R N
installed and configured with a valid input.
Reflects the value of the selected control temperature

determine if a brownout condition exists . Also see AV:9 .
Reflects the value of the indoor relative humidity sensor, if
R N installed and configured with a valid input. The input is also
used to calculate the local space dewpoint value .
