BACnet Programmable TEC Dual Duct Two
Air Velocity Sensors Controller for Smoke
Control
The BACnet PTEC Dual Duct 2 AVS Controller is an
integral part of BACnet network. The controller
provides high performance Direct Digital Control
(DDC) technology for room temperature control in
Dual Duct Variable Air Volume (VAV) systems or air
volume setpoints and room temperature control in
Constant Volume (CV) systems. The DDC and related
components provide a totally electronic control
system.
The BACnet PTEC 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
 Communicates using BACnet MS/TP protocol for
open communications on BACnet MS/TP
networks.
 BTL listed as a B-ASC device.
 Auto-discovery and Auto-addressing over entire
MS/TP network.
 Programmable using PPCL.
 Setpoints and control parameters assigned and
changed locally or remotely.
 Setpoints and control parameters stored in
Electrically Erasable Programmable Read Only
Memory (EEPROM)—no battery backup required.
 Returns from power failure without operator
intervention.
 No calibration required, thereby reducing
maintenance costs.
 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.
 PID control of HVAC systems minimizes offset
and maintains tighter setpoint control.
 Unique control algorithms for specific applications.
 Separate air volume setpoints for occupied and
unoccupied modes (CV Applications only).
 Uses proven DDC architecture.
