Zone Controllers
The Zone Controllers are mounted in snap-track which is typically located in the control
enclosure on each zone damper. Orient the board in the snap-track so that the actuator,
flow sensor (optional), and auxiliary relay board (optional) cables will reach their respec-
tive connectors on the Zone Controller. Carefully press the board into the snap-track to
avoid damaging any of the electronic components on the circuit board. To remove a
board from the snap-track, carefully pull one edge of the snap-track away from the board
with your fingers and remove the board.
Caution: Do not use any tools to pry the board loose. This will damage the
board and/or snap-track.
Warning:
When mounting the snap-track, be sure the heads of the screws do not
protrude far enough to touch the bottom of the Zone Controller circuit
board.
Consider serviceability of the location when mounting the Zone Controllers. They should
be easily accessible to facilitate servicing.
Tip: Use small stickers on the ceiling grid or tiles to help future service personnel
locate system components. If you use small stickers from an office supply store,
you can get different colors to code the location of various components.
