controller is designed for operation and modification
without vendor assistance.
If required, new custom code using our 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 Siemens BACnet PTEC Unit Conditioner
Controller consists of an electronic controller
assembly.
The controller interfaces with the following external
devices:
 Floating control valve and damper actuators
 Temperature sensors (room, pipe, and duct)
 Service and commissioning tools
 Digital input devices (dry contacts from motion
sensors, alarm contacts, switches)
 Digital output devices (fan speeds, stages of heat,
stages of cooling)
Room Sensor
The room sensor connection to the controller board
consists of a quick-connect RJ-11 jack. This
streamlines installation and reduces controller start-up
time.
Combination Temperature and Relative
Humidity Models
The Series 2200 range of TEC room units includes
combination temperature and humidity models. For
these models, both temperature and relative humidity
values are passed digitally to the TEC. This
information is passed from the room unit through the
RJ-11 cable to the RTS port on the TEC. See the
Series 2200 Temperature Room Units for TEC and
ATEC Technical Specification Sheet
(149-820), for
more information.
