Siemens BACnet Programmable TEC Unit
Conditioner Controller for Smoke Control
The Siemens BACnet PTEC Unit Conditioner
Controller is an integral part of BACnet network. The
controller provides high performance Direct Digital
Control (DDC) of pressure-dependent terminal boxes,
fan coil units, and unit conditioners.
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.
 Plenum rated controller.
 User adjustable offset for the room temperature
reading when required for validation purposes.
Applications
Pressure Dependent Terminal Boxes
 Cooling or Heating (Application 6640)
 Cooling and Hot Water Heat (Application 6641)
