Commissioning Sensor
Description
The Commissioning Sensor is a cost-effective
discharge air sensor used with controllers. It is
designed to be installed quickly into metal ductwork
and to connect to the controller's auxiliary sensor port
to provide a discharge air temperature point for use
with automated commissioning tools. The sensor's
resistance varies proportionally to the actual duct air
temperature being measured.
Applications
The controller uses the commissioning sensor when a
simple indication of duct temperature change is
needed. These sensors are also well-suited for
proofing HVAC equipment in heating and cooling
applications prior to the installation of room sensors.

The commissioning sensor is not recommended for
closed-loop control or for applications where precise
temperature monitoring is required.
NOTE: An RJ-11 jack SHOULD NOT be added to
the 10K sensor leads for input into an RTS
port on a Siemens Terminal Equipment
Controller. The resulting sensor will not
work in this configuration, and is only
designed for use by an auxiliary input.
