Compatibility & Fitment
- Fits Hayward E-Command 4 / HPC-4 automation systems.
- Use when the original control board is failing, the display is unresponsive, or multiple equipment relays are malfunctioning.
- Designed to be a direct replacement for systems specifying part number GLX-PCB-HPC-4.
Features & Specifications
- Controls up to 4 equipment loads (pumps, heater, lights, cleaner, etc.).
- Includes four high-voltage relays for external equipment control.
- Supports AquaConnect home network integration.
- Manufactured by Hayward for long-term reliability in pool system automation.
Installation Notes
Turn off all power sources to the controller and pool equipment. Remove the old board, disconnect all wiring and label connections for reference. Mount the new GLX-PCB-HPC-4 board in the existing enclosure, reconnect wires matching the original layout, restore power and test each controlled equipment function to ensure correct operation.
Maintenance Tip
Inspect council connections and relays annually. If you experience erratic behavior, equipment failures or display errors, replacing the control board with this unit often restores full automation functionality.
