BACnet ATEC Controller for Smoke Control
The BACnet Actuating Terminal Equipment Controller
(ATEC) is an integral part of the BACnet network. The
controller provides high performance direct digital
control (DDC) of pressure-independent, variable-air-
volume zone-level routines. The BACnet ATEC can
operate stand-alone or can be networked to perform
complex HVAC control, monitoring and energy
management functions and is designed to reside on
any BACnet control system.
Features
 UL864 Listed for Smoke Control
 Controller integrated with actuator for ease of
installation.
 PID control of HVAC systems minimizes offset
and maintains tighter setpoint control.
 Communicates using BACnet MS/TP protocol for
open communications on BACnet MS/TP
networks.
 BTL Listed as a B-ASC device.
 BACnet VAV Actuator requires only 5 VA, an
advantage when sizing electrical capacity.
 Unique control algorithms for specific applications.
 Setpoints and control parameters assigned and
changed locally or remotely.
 Electrically Erasable Programmable Read Only
Memory (EEPROM) used for storing setpoints
and control parameters—no battery backup
required.
 Return from power failure without operator
intervention.
 No calibration required, thereby reducing
maintenance costs.
 Auto-discovery and Auto-addressing over entire
MS/TP network.
 Advanced digital room unit for temperature, CO
2
,
and relative humidity.
 Supports analog or digital room units with either
absolute or warmer-cooler setpoint adjustments.
 Includes a user-adjustable temperature offset for
the room temperature reading when required for
validation purposes.
 Automated fault detection and diagnostics
procedure for ease of startup/commissioning and
troubleshooting.
Applications
Operating independently, or as part of a BACnet
System, the BACnet ATEC can control the following
VAV pressure- independent zone applications:
 Slave Mode (Application 6684)
 VAV Cooling Only (Application 6630)
 VAV Cooling or Heating (Application 6631)
 VAV with Electric Reheat or Baseboard Radiation
(Application 6632)
 VAV with Hot Water Reheat (Application 6633)
