Hardware
Controller Board
The Actuating Terminal Equipment Controller (ATEC)
VAV with Reheat and the Base VAV consists of an
electronic controller, a differential pressure sensor
and a damper actuator assembly.
This controller provides all wiring terminations for
system and local communication and power. The
cable from the room sensor (purchased separately)
connects to an RJ-11 jack on the controller. All other
connections are removable terminal blocks. The
controller assembly, with integral actuator, is mounted
directly on the terminal box damper shaft.
The ATEC VAV with Reheat has two AI (100K Ω
thermistor) or DI inputs and two Triac type digital
outputs. The ATEC Base VAV controller has no
additional input/outputs.
In addition to controlling the integrated damper
actuator, both controllers interface with the following
external devices (purchased separately):
 Room temperature sensor with optional setpoint
dial and night override button
 Service and commissioning tools
 Building Automation System from Siemens
Industry, Inc.
Room Sensor/Room Unit
The room sensor connection to the controller board
consists of a quick-connect RJ-11 jack. This
streamlines installation and reduces controller start-up
time.
Differential Pressure Sensor
The differential pressure sensor is easily connected to
the box’s air-velocity sensing elements to provide
measurement of the differential pressure. The
measured value is converted to actual airflow in cfm
(lps) by the controller.
