SERVICE-PART, MAIN PCB, HPC-4(EC | GLX-PCB-HPC-4
Hayward HPC-4 Main PCB (GLX-PCB-HPC-4) is the central control board for managing and automating various functions of your pool system. Here's a breakdown of how it works and its role in your pool setup:
- Control and Automation
- The Main PCB is the "brain" processing user inputs and operating your pool equipment automatically or manually.
- It connects to other components such as pumps, heaters, valves, and lights, to control their operation based on settings or schedules.
- Features It Manages
- Pump Control: Regulates the pool pump's on/off cycles and speed if you're using a variable-speed pump.
- Heater Activation: Turns the pool or spa heater on or off based on the desired water temperature.
- Lighting: Controls pool and spa lighting, often with color options and schedules.
- Valves: Operates automated valves for features like waterfalls, spa jets, or switching between pool and spa modes.
- Sanitization Systems: May manage chlorinators or saltwater generators to maintain pool chemistry.
- User Interface
- The PCB connects to a control panel where users can set schedules, monitor temperatures, and activate or deactivate features.
- Many systems also support remote controls or smartphone integration via apps for convenient management.
- Sensors and Inputs
- The board uses sensors to gather information, such as water temperature or flow rate, to make decisions.
- Inputs from the user (manual control) or pre-set schedules dictate its operation.
- Power Distribution
- It's a hub for distributing power to various components, ensuring they operate efficiently and safely.
- Communication
- Modern systems often allow communication with remote devices, enabling control via Wi-Fi or proprietary remote systems.
