Will This Replace My Existing Spa Control?

The BP7 can replace many older Balboa VS and EL control systems when paired with a compatible topside keypad, such as the included TP500. It may also suit other spa control retrofit applications after checking the equipment and installation requirements.

Compatibility depends on your spa’s pump speeds and voltages, circulation system, blower, accessories, plumbing, and available mounting space. Existing equipment cords or plumbing may require adaptation.

Replacing an older keypad? Check the TP500 dimensions and adapter-plate coverage against your existing opening before ordering.

Specifications

Before You Install

The BP7 must be configured for the equipment connected to it. Pump and accessory voltages, equipment connections, heater alignment, and electrical supply requirements must be verified during installation.

Installation should be completed by a qualified spa technician or electrician following the instructions supplied with the system.

Frequently Asked Questions

Does this kit include the keypad?
Yes. The TP500 keypad, overlay, adapter plate, and spa light cord are included.

Can I reuse my existing pumps?
Often, provided their voltage, speeds, current requirements, and connections are compatible with the selected BP7 configuration. Send us your pump-label photos for help checking.

Can I keep my old topside keypad?
Compatibility depends on the keypad model. Older VS and EL keypads generally require replacement with a compatible BP-series interface. This kit includes the TP500 for that upgrade.

Is this a direct replacement for every spa?
Fitment varies. Configuration changes, equipment cords, keypad-opening adjustments, or plumbing modifications may be needed.
