Control algorithms are preprogrammed. The controller
is ready to operate after selecting the application and
assigning the unit’s controller address. If desired, the
operator may adjust the air volume setpoints in cfm
(lps), room temperature setpoints and other
parameters. The controller is designed for operation
and modification without vendor assistance.
Hardware
Controller Board
The BACnet Actuating Terminal Equipment Controller
(ATEC) 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 is mounted directly on a damper
shaft.
A specific enclosure and power supply are required in
order to meet the stringent smoke control standards.
See the
Product Ordering Information table for part
numbers.
The BACnet ATEC has two AI or DI (10K/100K Ω
thermistor, selectable), one analog output (0-10Vdc)
and 4 Triac type digital outputs.
In addition to controlling the integrated damper
actuator, the controller interfaces 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.
UL864 Listed for Smoke Control
The BACnet ATEC hardware has passed stringent
electrical and thermal tests that ensure increased
product reliability and performance as a part of a
Siemens engineered smoke control system. The
BACnet ATEC is used to control the operation of the
fans and dampers based on the smoke control
strategy being initiated in the supervisory controller.
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.
Combination Temperature, Carbon Dioxide,
and Relative Humidity Models
The Series 2200/2300 range of room unit, usable with
the BACnet Programmable TEC (PTEC/ATEC)
includes temperature only or combination
temperature/humidity, temperature/CO
2
, or
temperature/CO
2
/humidity models. For these models,
all measurement variables—CO
2
, temperature and
relative humidity values—are passed digitally to the
PTEC/ATEC. This information is passed from the
room unit through the RJ-11 cable to the RTS port on
the PTEC/ATEC.
NOTE:
A CO
2
power module (product
number AQM2200) is also
needed for the CO
2
sensor
option to function.
