Installing the Termination Board
1. Remove the controller from its packaging and separate the top and
bottom frames.
2. Using the bottom frame (with termination board) as a template, mark
the four (4) mounting hole locations on the mounting surface. If the
mounting surface is metal and earth grounded, mark the location of
the termination board ground hole. If not, proceed to the next step.
3. Set the controller aside and drill four (4) holes at the marked
mounting locations large enough for #8 (4 mm) screws [not supplied].
Avoid Equipment Damage!
Self-tapping sheet metal screws can result in loose metal shards
which may damage the board or cause it to malfunction. Start and
then remove each screw to ensure metal shards are not present
before mounting the bottom frame and termination board.
4. Secure the controller to the mounting surface with #8 (4 mm)
screws.
5. Provide an earth-to-ground connection using either of the following
options:
a. Drill a pilot hole at the termination board ground hole and install
a #8 (4 mm) screw through the ground hole. With this option, the
surface on which the bottom frame is mounted must be earth-
grounded; OR
b. Wire a ground connection from the 24 Vac common bus
termination to earth ground. Common bus terminations are
found on the board at 24VAC INPUT POWER.

Installing the Main Circuit Board
The controller does not ship with the top plastic frame installed. The
board can be kept in its installed room location and programmed while
the enclosure is mounted and wired.
Note: It is not possible to program the main circuit board without
connecting it to a termination board. If choosing to program the main
circuit board in a different location, a termination board is required.
After completing programming, connect the circuit board to the
termination board. To begin, verify that the 24 Vac power cable is not
connected to the termination board, and then install the main circuit
board as shown below.

Important: The 60-pin cable ejector is designed to eject the 60-pin cable when disconnecting
(refer to the lower right inset above). Ensure that the slot keys are aligned when connecting
the 60-pin cable to the 60-pin cable
1. Hold the top frame (A) at a 90° angle to the bottom of frame (B).
2. Connect the 60-pin cable (C) to the 60-pin cable ejector slot (D) by
pressing down firmly on the cable until the ejector tabs collapse and
snap over the ends of the cable (refer to the bottom left inset above).
Then, connect the 20-pin cable (E) to the 20-pin slot (F).
3. Align the snaps on the top frame (G) with the mounting locks on the
bottom frame and then push the two frames together in the direction

indicated by the arrows. For controllers with an operator display,
connect the operator-display cable to the circuit board.
4. Locate the 24 Vac power connector on the termination board and
then remove the mating plug and screw terminals. Attach the 24 Vac
power-supply cable to the screw terminals on the mating plug.
5. Connect the 24 Vac power cable to the termination board (H). The
green status LED will light.
