Siemens BACnet Programmable TEC Heat
Pump Controller—Multi-Stage
The Siemens BACnet PTEC Heat Pump Controller
provides high performance Direct Digital Control
(DDC) technology for room temperature control of
heat pumps. The BACnet Heat Pump Controller and
related components provide a completely electronic
control system.
The Siemens BACnet PTEC Heat Pump 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.
 Supports Room Sensor with relative setpoint
adjustment.
 Control capable of modulating floating control
electronic or electric damper actuator.
 Damper status can be reported in either
percentage open notation with floating control or
in voltage notation with 0-10 Vdc actuators.
 User-adjustable offset for the room temperature
reading when required for validation purposes.
Applications
 Slave Mode (Application 6590)
 Multiple Compressor Heat Pump with Reversing
Valve and Mixed Air Control (Application 6573)
 Multiple Heating and Cooling Heat Pump with
Mixed Air Control and Internal Reversing Valve
(Application 6574)
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
