ATEC Base VAV Controller & VAV Reheat
Controller
The ATEC Base VAV and VAV Reheat Controllers,
with integral damper actuator, provide high
performance direct digital control (DDC) of pressure-
independent, variable-air-volume zone-level routines.
The ATEC can either operate stand-alone or be
networked to perform complex HVAC control,
monitoring and energy management functions. It is
designed to reside on any Siemens control system.
Features
 Controller integrated with actuator for ease of
installation.
 PID control of HVAC systems minimizes offset
and maintains tighter setpoint control.
 Unique control algorithms for specific applications.
 ATEC Base VAV Actuator requires only 5 VA, an
advantage when sizing electrical capacity.
 Plenum rated controller.
 Setpoints and control parameters assigned and
changed locally or remotely.
 Electrically Erasable Programmable Read Only
Memory (EEPROM) used for storing setpoints
and control parameters—no battery backup
required.
 Return from power failure without operator
intervention.
 No calibration required, thereby reducing
maintenance costs.
 Automated fault detection and diagnostics
procedure for ease of startup/commissioning and
troubleshooting.
Applications
ATEC Base VAV Controller
 VAV Cooling Only (Application 2520)
 VAV Cooling or Heating (Application 2521)
 Slave Mode (Application 2486)
ATEC VAV with Reheat Controller
 VAV Cooling Only (Application 2500)
 VAV Cooling or Heating (Application 2501)
 VAV with Electric Reheat or Baseboard Radiation
(Application 2522)
 VAV with Hot Water Reheat (Application 2523)
 VAV Series Fan Powered with Electric Reheat
(Application 2524)
 VAV Parallel Fan Powered with Electric Reheat
(Application 2526)
 Slave Mode (Application 2473)
Control algorithms are preprogrammed. The controller
is ready to operate after selecting the application and
assigning the unit’s controller address. 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.
