Siemens BACnet Programmable TEC Dual
Duct Two Air Velocity Sensors Controller for
Smoke Control
The Siemens BACnet PTEC Dual Duct Controller
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 DDC can
operate independently, stand-alone or networked to
perform complex HVAC control, monitoring and
energy management functions. This controller 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.
 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.
 Meets low dict static pressure requirements
 PID control of HVAC systems to minimize offset
and maintain tighter setpoint control.
 Unique control algorithms for specific applications.
 No calibration required, thereby reducing
maintenance costs.
 Separate minimum and maximum air volume
seeting for heating and cooling modes.

Separate air voume setpoints for occupied and
unoccupied modes (CV Aplication only).
Applications
 Constant Volume – Two Inlet Sensors with
Optional Reheat (Application 6565)
 Constant Volume – One Inlet and One Outlet
Sensor with Optional Reheat (Application 6566)
 Variable Air Volume – Two Inlet Sensors with
Optional Reheat (Application 6567)
 Variable Air Volume – One Inlet and One Outlet
Sensor with Optional Reheat (Application 6568
)
