ATEC Base VAV Controller & ATEC VAV
Reheat Controller
Description
The ATEC (Actuating Terminal Equipment
Controller) Variable Air Volume Controllers provides
high performance direct digital control (DDC) of
pressure-independent, variable-air-volume zone-
level routines. The ATEC controllers can operate
stand-alone or can be networked to perform
complex HVAC control, monitoring and energy
management functions. The ATEC controllers are
designed to reside on any Siemens control system.
Features
• Controller integrated with actuator for ease of
installation.
• Automated checkout procedure for ease of
startup/commissioning and troubleshooting.
• PID control of HVAC systems to minimize
offset and maintain tighter set point control.
• HVAC diagnostic capability at the BLN level
using the TBC Test Tool in CT 4.8.
• ATEC Base VAV Controller requires only 3.5
VA, an advantage when sizing electrical
capacity.
• 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.
• Return from power failure without operator
intervention.
• No calibration required, thereby reducing
maintenance costs.
Applications
Operating independently, or as part Siemens
APOGEE System, the ATEC VAV Controller can
control the following VAV pressure- independent
zone applications.
ATEC Base VAV Controller:
• VAV Cooling Only (Application 2520—similar
to 2020 for the ATEC)
• VAV Cooling or Heating (Application 2521—
similar 2021)
• Slave Mode (Application 2486)
ATEC VAV with Reheat Controller:
• VAV Cooling Only (Application 2500—similar
to 2020)
• VAV Cooling or Heating (Application 2501—
similar to 2021)
• VAV with Electric Reheat or Baseboard
Radiation (Application 2522—similar to 2022)
