TEC Constant Volume Controller
The TEC Constant Volume Controller provides high
performance Direct Digital Control (DDC) technology
for supply air flow and temperature control of constant
volume systems. The TEC Constant Volume
Controller can operate either stand-alone or be
networked to perform complex HVAC control,
monitoring and energy management functions. This
controller is designed to reside on the Siemens
Industry control system.
Features
 Advanced PID algorithm for the temperature
control loops is employed to provide stability and
to reduce unnecessary changes in the Flow
setpoint when the room temperature is at or near
the room temperature setpoint.
 Unique control algorithms for specific applications.
 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.
 Reports airflow in cfm (lps).
 Meets low duct static pressure requirements.
 Separate minimum and maximum air volume
setting for heating and cooling modes.
Applications
 Slave Mode (Application 2092)
 Constant Volume Cooling Only (Application 2030)
 Constant Volume with Electric Reheat
(Application 2032)
 Constant Volume with Hot Water Reheat
(Application 2033)
Control algorithms are pre-programmed. The
controller is ready to operate after selecting the
application. If desired, the operator may adjust the
room temperature setpoints and other parameters.
The controller is designed for operation and
modification without vendor assistance.
Hardware
Controller Board
The TEC Constant Volume Controller consists of an
electronic controller assembly and on-board
differential pressure sensor.
This controller provides all wiring terminations for
system and local communication and power. The
cable from the room sensor (purchased separately)
