Siemens BACnet Programmable TEC Unit
Vent Controller
The Siemens BACnet PTEC Unit Vent Controller
provides high performance Direct Digital Control
(DDC) technology for room temperature control in unit
ventilators. The Unit Vent Controller and related
components provide an electronic control system. The
Siemens BACnet PTEC Unit Vent Controller 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. The electronic approach
to temperature control includes the following features.
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.
 No calibration required, thereby reducing
maintenance costs.
 PID control of HVAC systems to minimize offset
and maintain tighter setpoint control.
 Unique control algorithms for specific applications.
 Control capable of modulating 0-10V valve
actuators and damper actuators.
 Optional Temperature Offset.
Applications
 Slave Mode (Application 6595)
 Heating and/or Chilled Water Cooling, ASHRAE
Cycles l and II (Application 6575)
 Heating and/or Chilled Water Cooling, ASHRAE
Cycle III (Application 6576)
 Heating and DX Cooling, ASHRAE Cycles I and II
(Application 6577)
 Heating and DX Cooling, ASHRAE Cycle III
(Application 6578)
 Nesbitt Cycle W (Application 6579)
Heating can be provided by hot water, steam or
electric heat while cooling can be chilled water or DX
coils.
