desired, the operator may adjust the room
temperature setpoints and other parameters. The
controller is designed for operation and modification
without vendor assistance.
Hardware
Controller Board
The TEC Unit Vent Controller consists of an electronic
controller assembly.
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 unit ventilator. An optional
enclosure (P/N 550-002) protects the controller
assembly.
The controller interfaces with the following external
devices:
 0-10V Damper Spring Return Actuator
 0-10V Valve Spring Return Actuator
 Temperature sensors (room and averaging)
 Portable Operator's Terminal
 DDC Automation Systems
 Digital input devices (dry contacts from motion
sensors, alarm contacts)
 Digital output devices (fan, stages of electric heat,
DX cooling, 2 position valves)
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.
