Control algorithms are pre-programmed. 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 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.
Hardware
Controller Board
The BACnet PTEC Terminal Box (VAV) 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)
connects to an RJ-11 jack on the controller. All other
connections are removable terminal blocks. The
controller assembly is mounted on a plastic track that
mounts directly on the terminal box.
An optional enclosure (P/N 550-002) protects the
controller assembly.
Autozero Modules (optional devices) are available for
mounting with the controller for those applications
where uninterrupted airflow is necessary. An optional
Pneumatic Transducer provides control of pneumatic
damper and valve actuators.
The controller interfaces with the following external
devices:
 Averaging air velocity sensors provided by VAV
terminal unit manufacturers
 Floating or analog (0-10 Vdc) control valve and
damper actuators
 Temperature sensors (room, supply, discharge,
duct, immersion, and outside air)
 Service and commissioning tools
 Analog input devices (0-10 Vdc, 4-20 mA,
thermistor sensors, room temperature sensor,
room setpoint dial, auxiliary temperature sensor)
 Analog output devices (0-10 Vdc) valve and
damper actuators, variable speed fan control
 Digital input devices (dry contacts from motion
sensors, alarm contacts)
 Digital output devices (fan, stages of electric heat,
2 position valves, floating control actuators)
Combination Temperature, Carbon Dioxide,
and Relative Humidity Models
The Series 2200/2300 range of BACnet
Programmable TEC (PTEC) room units includes
temperature only or combination
temperature/humidity, temperature/ CO
2
, or
temperature/ CO
2
/humidity models. For these models,
all measurement variables— CO
2
, temperature and
relative humidity values—are passed digitally to the
PTEC. This information is passed from the room unit
through the RJ-11 cable to the RTS port on the
PTEC.
NOTE:
A CO
2
power module (product number
AQM2200) is also needed for the CO
2
sensor option to function.
