Tip
When you upload the input and output values of the
configured custom sensors, you will not obtain the exact
values which you configured earlier. There will be slight loss in
precision always.

Occupancy sensor
Operation
When an occupancy sensor is configured, this field enables you to configure the following control
operations to determine the behavior during scheduled unoccupied modes:
UnoccupiedCleaningCrew: Effective occupancy switches to standby for the comfort of the cleaning
crew.
ConferenceRoom: Effective occupancy stays unoccupied independent of the occupancy sensor
activity. During scheduled occupancy, occupancy sensor changes mode between standby and
occupied.
UnoccupiedTenant: When the occupancy sensor is active, effective occupancy switches to
occupied for the comfort of the tenant.
Custom Sensors
Sensor Name You can configure custom sensor types when using third party sensors with the controller. You can
create a maximum of two sensor types. This page allows you to configure a 10-point sensor
characteristic curve.
NOTE: Once the sensor is configured, the same sensor name is updated in the Input
Source drop-down list. Go back to Input Source and select the Custom Sensor.
Sensor Type Displays the sensor types such as Voltage, Resistive and Unconfigured.
Unit Measure Displays all unit categories supported by the controller.
Specification Sheet Unit
Type
Allows you to select the unit used in the specification sheet of the sensor. This allows you to define
the sensor characters easily by referring to the specsheet.
NOTE: The controller uses a 12-bit Analog-to-Digital converter. Please ensure that the sen-
sor provides adequate resolution in the target control range. To get best perfor-
mance, make sure that the target range of sensor signals that are important for the
application can be mapped to the entire range supported by the controller with ade-
quate resolution.
Application Unit Type This is the unit in which the sensor value will be read by the controller. To use the custom sensor for
any of the inputs expected by the controller, this unit needs to match the unit expected by the
controller.
These are the internal units used by the VAV control application:
Temperature: DegF Temperature
Setpoint: DDF or DegF
Humidity: %
CO2: ppm
Pressure: inches of water column
Import Use this action to share/reuse custom sensor definitions. The user can import the custom sensor
definitions from other controllers or stations.
Export Use this action to save the custom sensor in a text file.
NOTE: You must save the file with a .sen extension.
