Siemens BACnet Programmable TEC Dual
Duct Two Air Velocity Sensors Controller
The Siemens BACnet PTEC Dual Duct 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
 Communicates using BACnet MS/TP protocol for
open communications on BACnet MS/TP
networks.
 BTL listed as a B-ASC device.
 Programmable using PPCL.
 Plenum rated controller.
 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 duct 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
setting for heating and cooling modes.
 Separate air volume setpoints for occupied and
unoccupied modes (CV Application 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)
 Variable Air Volume with Changeover (Application
6569)
If required, new custom code using our PPCL
programming language can be added to replace or
supplement the standard application residing in the
