Siemens BACnet Programmable TEC Unit
Conditioner Controller
The Siemens BACnet PTEC Unit Conditioner
Controller provides high performance Direct Digital
Control (DDC) of pressure-dependent boxes, fan coil
units, and induction units. The Siemens BACnet
PTEC Conditioner 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.
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.
 Separate minimum and maximum air volume
setting for heating and cooling modes.
 User adjustable offset for the room temperature
reading when required for validation purposes.
Applications
Pressure Dependent Terminal Boxes
 Cooling or Heating (Application 6540)
 Hot Water Heat (Application 6541)
Fan Coil Units
 Cooling or Heating (Application 6550)
 Cooling and Heating (Application 6551)
 Two-stage Cooling and Electric Heat (Application
6552)
 Two-stage Cooling and Hot Water Heat
(Application 6553)
 Cooling and Electric Heat or VAV Pressure
Dependent with Electric Heat (Application 6554)
Control algorithms are preprogrammed. The controller
is ready to operate after selecting the application. If
desired, the operator may adjust the room
temperature setpoints and other parameters. The
