Description
The HLX-PCB-MAIN is a replacement Main Board for the OmniLogic pool controller.
Installation
DANGER of Death, Injury or Property Damage if procedure not followed. This accessory con-

lation. Power to the OmniLogic panel MUST be completely shut off before the dead front is removed.
Pre-2023 Models
Identify and Remove all Wiring Connections
Before you start disconnecting wires, you may want to take photos or mark the wiring with tape to
identify connections. These wires will be reconnected to the new OmniLogic Main Board included in
the kit. A general description of the connectors is shown below. Note that the sensor/interlock and
heater output screw terminal blocks will fit on the new OmniLogic Main Board. Rather than remove
each connection from the screw terminals, pull up on the entire terminal block to remove.
1. COMPLETELY DISCONNECT POWER TO THE CONTROL AND ITS ELECTRICAL PANEL.
2. Remove the deadfront panel to expose the Main Board.
3. Unfasten the screw holding the TurboCell extension board in place and then remove the board.
4. If using the optional I/O expansion board, disconnect all connections from the I/O expansion
board and then remove it from the plastic scaffolding.
5. Remove the Local Display by disconnecting the ribbon cable and pulling straight up.
6. Remove the plastic scaffolding by pulling each leg straight up away from the Main Board.
7. Take a picture of all wiring connections and then remove all connections. Refer to the graphic
below for wiring connection labels.

8. Loosen the two screws that secure the Main Board to the enclosure.
9. Remove the Main Board from the enclosure by lifting the board up and then out.
Replace the Main Board
With the old Main Board removed from the enclosure, install the new Main Board in its place. Note
that each wiring connection is in the same location as the old Main Board. The only difference is the
connector for the new remote Control Pad (not included). Refer to the illustration on page 4 for the
location of the new remote Control Pad connector.
1. Install TurboCell extension board into the new Main Board.
2. Mount the new Main Board into the enclosure by aligning the standoffs on the back with the
holes in the enclosure then pushing the Main board in and then down until it stops.
3. Secure the Main Board in place using the two screws that were previously loosened. Fasten the
TurboCell extension board with the previously removed screw.
4. Reattach all previously removed wiring connections. If you did not take a picture, refer to the
graphic above for wiring connections.
5. Reinstall the plastic scaffolding, local display, and I/O expansion board (if used).
6. Reinstall the deadfront panel.
Configuration
Now that the Main Board has been replaced, all wiring is reconnected, and the deadfront panel is in
place, the system is ready to be reconfigured.
1. Apply power to the OmniLogic system and wait for it to fully power on.
2. Navigate to the config wizard menu and follow the instructions in the OmniLogic Installation
manual to reconfigure the system.
