The Terminal Box Controller (Figure 1) is an integral
part of the APOGEE� Automation System. The
controller provides high performance Direct Digital
Control (DDC) technology for room temperature
control in Variable Air Volume (VAV) systems. The
Terminal Box Controller and related components
provide a totally electronic control system. The
Terminal Box Controller can operate independently,
stand-alone or networked to perform complex HVAC
control, monitoring and energy management functions
without relying on a higher level processor. The totally
electronic approach to temperature control includes
the following features.
Features
� PID control of HVAC systems to minimize offset
and maintain tighter set point control,
� Unique control algorithms for specific applications,
� Reports airflow in CFM (l/s),
� HVAC diagnostics through communication with a
Portable Operator's Terminal at a room sensor or
any field panel,
Technical Specification Sheet
Rev. 7, October, 1998
� Set points and control parameters assigned and
changed using the Portable Operator's Terminal,
� Electrically Erasable Programmable Read Only
Memory (EEPROM) used for storing set points
and control parameters�no battery backup
required,
� Returns from power failure without operator
intervention,
� Meets low duct static pressure requirements,
� Uses proven APOGEE Automation System DDC
architecture,
� No calibration required, thereby reducing
maintenance costs, and
� Separate minimum and maximum air volume
setting for heating and cooling modes.
Applications
Operating independently, or as a part of the APOGEE
Automation System, the Terminal Box Controller can
control a variety of Variable Air Volume (VAV) pressure
independent terminal box applications, including:
� VAV Cooling Only,
� VAV Cooling or Heating,
� VAV with Hot Water Reheat (proportional),
� VAV with Electric Reheat (one-, two-, or threestage),
� VAV Fan Powered Series or Parallel with Hot
Water Reheat, and
� VAV Fan Powered Series or Parallel with Electric
Reheat (one-, two-, or three-stage).

Description
The Terminal Box Controller consists of a differential
pressure transducer and an electronic controller
assembly. An Autozero Module is available for
mounting on the controller for those applications
where uninterrupted airflow is necessary. A Pneumatic
Transducer provides for control of pneumatic damper
and valve actuators.
Control algorithms are preprogrammed. The controller
is ready to operate after selecting the application and
assigning the unit's controller address with the
Portable Operator's Terminal. If desired, the operator
may use the Portable Operator's Terminal to adjust
the air volume set points in CFM (l/s), room
temperature set points and other parameters. The
controller is designed for operation and modification
without vendor assistance.
Differential Pressure Transducer
The averaging air velocity sensor (provided by the VAV
terminal unit manufacturer) sends an average air
velocity measurement of the duct air velocity to the
controller. The air velocity sensor connects to the
differential pressure transducer (which is mounted in
the Terminal Box Controller) and measures the
average differential pressure. The Terminal Box
Controller converts this value to actual airflow in CFM
(l/s).

Terminal Box Controller
This controller provides all wiring terminations: input/
output, system and local communication and power.
The cable from the room sensor connects to a RJ-11
jack on the controller. All other connections are
removable terminal blocks. The controller assembly is
mounted on a plastic track that is mounted directly on
the terminal box. An optional enclosure protects the
controller assembly.
The controller interfaces with the following external
devices:
� Averaging air velocity sensor provided by VAV
terminal unit manufacturers,
� Floating control valve and damper actuators,
� Temperature sensors (room, duct, immersion, and
outside air),
� Portable Operator's Terminal,
� APOGEE Automation System,
� Digital input devices (dry contacts from motion
sensors, alarm contacts), and
� Digital output devices (fan, stages of electric heat).

Optional Accessories
Autozero o Module
The optional Autozero Module (Figure 2) is required
when continuous operation at occupied flow is
required for an area. The Autozero Module is
connected to the air velocity inlet ports of the Terminal
Box Controller and provides periodic recalibration of
the air velocity transducer without changing air volume
being delivered to a room. This recalibration ensures
long-term precise airflow delivery.

Pneumatic Transducer
The PTS Pneumatic Transducer (Figure 3) contains the
transducers that provide the signal conversion from
electronic to pneumatic. The module is piped to the
pneumatic actuator and wired to the Terminal Box
Controller. This transducer provides for accurate
control of pneumatic actuators for precise temperature
and air volume control.

Terminal Box Controller Communication
Up to 32 Terminal Box Controllers or other Terminal
Equipment Controllers can be connected to each of
the three field panel LAN trunks. Communication with
the Terminal Box Controller can be initiated from any
system field panel on the system network. The
system network does not require additional hardware
to connect Terminal Equipment Controllers. When
Terminal Equipment Controllers are wired to a field
panel, features such as energy management
programs, alarm reporting, centralized control,
modification of the system database, system-wide
troubleshooting, and the global commanding of
devices are available to them.
Portable Operator's Terminal
The DOS-based laptop computer serving as the
Portable Operator's Terminal can communicate with
Terminal Box Controllers or any field panel. The
terminal connects to the controller, the room
temperature sensor associated with the Terminal Box
Controller or field panel. The terminal can be used to
remotely adjust air volume settings or temperature set
points, to troubleshoot and start-up the system. When
connected to the RS-232 port of a field panel, the
terminal provides system-wide communication. The
terminal uses full English language for all functions,
eliminating the need to remember coded commands.
