These three terms get used interchangeably, but they're different parts, and knowing which one you need narrows the search fast:

What It Does |
Where It Lives |
|
Control board (PCB) |
The internal circuit that reads sensors and switches relays to run pumps, heaters, and lights |
Inside the equipment pad enclosure or spa cabinet |
|
Control panel / keypad |
The buttons, touchscreen, or overlay you actually press to set functions |
Mounted on the equipment or spa's topside, wired back to the board |
|
Enclosure / junction box |
Weatherproof housing that protects the board or wiring connections from the elements |
Mounted near the equipment pad, outdoors in most residential setups |
This collection covers Balboa Water Group and Gecko, both widely used in spa and hot tub control systems; Pentair and Hayward, common in residential and commercial pool automation; Intermatic, known for timers and enclosures rather than smart panels; Jacuzzi, used in jetted tub and spa PCBs; and smaller-volume brands including AquaCal, AquaComfort, Aqua Creek, Caretaker, and Raypak for heater and specialty control parts. Stock varies by brand and part number, so search by the exact model printed on your existing board or panel rather than by brand alone.
A pool heater control panel is the interface that sets water temperature and manages burner or heat pump cycling, separate from the pump or lighting controls on the same system. Heater-specific panels and boards in this collection come from brands like Raypak, Pentair, and Hayward, and are generally not interchangeable with a pump or general automation control board even on the same equipment pad. Match the replacement to your heater's brand and model number, not just to "pool control panel" as a category, since a mismatched board won't communicate correctly with the burner or ignition system.
Start with the part number printed directly on the board or panel label, not just the equipment brand, since most manufacturers use several board revisions across a single product line. If the label is unreadable, the system voltage (typically 120V or 240V) and what the board controls, such as a single pump versus a pool/spa combo, narrows the search further. Universal or newer automation panels can sometimes bridge multiple brands, but confirm wiring and communication protocol compatibility before ordering rather than assuming. For the automation systems these boards plug into, browse that collection separately.
