Temperature Sensors
Temperature sensors used with the TEC Constant Volume Controller include an
electronic room temperature sensor and an optional duct temperature sensor.
Room Temperature Sensor
The 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.
Actuators
Actuators used with the TEC Constant Volume Controller include electronic damper
motors, electronic valve motors, and electronic valve assemblies. These actuators are
powered through the controller to position cooling and/or reheat valves or supply air
dampers.
