Temperature Sensors
Temperature sensors used with the PRC-OAVS with Floating Damper, AOV or
Floating Reheat, (optional) Discharge Temperature Control and AOV Perimeter
Heating include an electronic room temperature sensor and an optional duct
temperature sensor.
Room Temperature Sensor
The controller room temperature sensor connects to the controller by means of a cable
terminated at both ends with a six-conductor RJ-11 plug-in connector.
See the Ordering Notes section for the location of the room temperature
sensor/Human Machine lnterface (HMl) port.
NOTE:
When using a Series 2000 Room Thermostat:
During
unoccupied mode, you cannot change the Room Setpoint using a Siemens
Industry Series 2000 thermostat. Any attempt to change Room Setpoints during
unoccupied mode using a Series 2000 stat will be ignored.
During
occupied mode, the Room Setpoint can be changed using a Series 2000 stat,
but if it is, then the controller initial values should be uploaded to the field panel.
Otherwise the controller will not keep the adjusted Room Setpoint value upon return
from a power failure.
Duct Temperature Sensor
An optional duct temperature sensor provides duct air temperature sensing inputs to
the controller.
For more information about temperature sensors, contact your local Siemens Industry
representative.
Discharge Temperature Sensor
An optional discharge temperature sensor provides BTU compensation sensing to the
controller.
Actuators
Actuators used with the PRC-OAVS with Floating Damper, AOV or Floating Reheat,
(optional) Discharge Temperature Control and AOV Perimeter Heating include
electronic damper motor. This actuator is controlled by the controller to position the
damper or air valve.
