Siemens BACnet Programmable TEC
Constant Volume
The Constant Volume Controller is an integral part of
BACnet network. The controller provides high
performance Direct Digital Control (DDC) technology
for room pressure and temperature control of constant
volume systems. The Constant Volume Controller can
operate stand-alone or can be 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.
 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.
 UL and cUL Listed for Energy Management
Equipment.
 Setpoints and control parameters assigned and
changed locally or remotely.
Applications
 Slave Mode (Application 6594)
 Constant Volume Cooling Only (Application 6560)
 Constant Volume with Electric Reheat
(Application 6562)
 Constant Volume with Hot Water Reheat
(Application 6563)
Control algorithms are preprogrammed. The controller
is ready to operate after selecting the application. If
desired, the operator may adjust the air volume
setpoints in cfm (lps), room temperature setpoints and
other parameters. The controller is designed for
operation and modification without vendor assistance.
If required, new custom code using our PPCL
programming language can be added to replace or
supplement the standard application residing in the
controller. This provides the flexibility to meet many
job specifications with the assurance of having a
proven and tested standard application to rely upon.
