Service-Part, Main Pcb, Hpc-4 (Ecommand 4) | GLX-PCB-HPC-4

Compatibility
The GLX-PCB-HPC-4 is a replacement main board for the ECOMMAND 4 (HPC-4) pool control. This circuit
board is compatible with all ECOMMAND 4 models including HPC-4, HPC-4-ACT, HPC-4-RC, and HPC-4-ACTRC.
Circuit Board Replacement
1. Record the System Settings: The Configuration, Timers, and Settings menus contain all of the information regarding how the ECOMMAND 4 is programmed to operate a specific pool system. This information
is stored on the main PCB and it is very important that all of this information gets transferred from the old
PCB to the new PCB. Record all programming information (Configuration menu, Timers menu, and Settings menu) before attempting to replace the board.
2. Remove the old board: Make sure that ALL circuit breakers are OFF prior to PCB removal.
a. Remove metal panel to expose the local display and circuit board.
b. Remove the local display by pulling up and unplugging cable.
c. Unplug the sensor and display communication terminal blocks from the old PCB – you don’t need to
disconnect/reconnect individual wires.
d. Remove transformer wires and any other wires that are connected to the old board, making note of
their locations.
e. Remove the board by loosening the 2 mounting screws and sliding the board forward and up. When
the board comes loose from the enclosure, pull it up and out.
3. Install the new GLX-PCB-HPC-4 circuit board:
a. Install the new board using the two mounting screws.
b. The locations of the transformer lugs may be different from the old board.
c. Connect the remaining wires including the sensor and display communication terminal blocks onto
the new circuit board. If there are any questions about wiring locations, refer to your Installation
manual.
d. Plug in and install the local display.
e. Replace metal panel.
