Step 2: Add Analog Sensed Value Input microblocks
From the Net I/O microblock menu, add one Analog Sensed Value Input ( ASVI ) microblock for each type
of sensed value (temperature, humidity, CO2, or VOC) that you want to retrieve from the ZS sensor(s). For
example, the first ASVI may retrieve temperature, and the second may retrieve humidity, etc. A control program
can have only one ASVI for each type of sensed value. Enter the following information in the Property Editor.
NOTE If your control program needs to retrieve temperature or humidity values from ZS zone sensors and ZS duct
or pipe sensors, use the same ASVI microblock and select the Zone Temp or Zone Humidity Rnet tag.
Rnet Tag The Rnet tag determines which value (Temperature, Humidity, CO2, or VOC)
is retrieved from the ZS Sensor. A zone sensor's screen will display:
or for Zone Temp
Zone Humidity
CO2 for Zone CO2
UOC for Zone VOC
Default Value The value that the microblock outputs when communication with all enabled
sensors fails or during sensor startup.
Units The unit of measurement of the microblock's present value. Select from the
BACnet engineering units in this droplist. For some microblocks, you can
customize the droplist by selecting Options > Preferences > Droplist Options .
Index/Enable The Index number corresponds to the ZS sensors defined in the Sensor
Binder microblock. Check Enable for each sensor that you want to include in
the combination algorithm used to determine the output value of the
microblock.
