Step 2: Add Analog Sensed Value Input microblocks
From the
microblock menu, add one
Analog Sensed Value Input
(
) 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.
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
or
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
for Zone CO2
for Zone VOC
The value that the microblock outputs when communication with all enabled
sensors fails or during sensor startup.
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

.
The Index number corresponds to the ZS sensors defined in the Sensor
Binder microblock. Check
for each sensor that you want to include in
the combination algorithm used to determine the output value of the
microblock.
