Balboa BP7 5.5kW Spa Control Retrofit Kit with TP500 – G6505

The Balboa BP7 G6505 5.5kW Spa Control Retrofit Kit with TP500 provides a modern replacement solution for many older Balboa hot tub and spa control systems. Built around Balboa's highly configurable BP7 platform, this retrofit kit is designed to replace many aging or discontinued spa controls while providing a current Balboa control system and topside interface.

The G6505 kit combines a Balboa BP7 control system with a 5.5kW heater and TP500 topside control. The BP7 platform can be configured for a wide range of spa equipment combinations, making it an excellent option when the original control box or circuit board is obsolete or no longer available.

Modern Replacement for Older Balboa Spa Controls

One of the biggest advantages of the Balboa BP7 is its ability to replace many older Balboa control platforms. Balboa designed the BP7/8 platform specifically with aftermarket retrofit applications in mind.

Depending on the original spa equipment and configuration, the BP7 platform can be used when replacing many controls from the following older Balboa families:

• Balboa VS Series
• Balboa GS Series
• Balboa EL Series
• Balboa ML Series
• Many other compatible Balboa and non-Balboa spa control applications

Important: BP7 compatibility is determined by the equipment installed in the spa and the required BP7 setup. Matching only the appearance of the original control box is not enough to confirm compatibility.

Highly Configurable BP7 Platform

Unlike a control system designed for only one equipment combination, the BP7 platform supports numerous configurations. Depending on the selected setup and electrical requirements, BP7 can operate combinations of:

• Pump 1
• Pump 2
• Pump 3
• Additional pump configurations
• Circulation pump
• Blower or auxiliary equipment
• Ozone system
• Spa lighting
• Compatible Balboa accessories

The exact BP7 setup must be selected according to the pumps, circulation system, blower, ozone, lighting and other equipment installed in the spa.

5.5kW Heater

The G6505 version uses Balboa's 5.5kW BP7 heater configuration. Balboa also offers BP7 retrofit systems with a 4.0kW heater for applications requiring that configuration.

When replacing an existing spa pack, the heater rating and electrical requirements should be verified before ordering.

Includes Balboa TP500 Topside Control

The G6505 retrofit kit includes a Balboa TP500 topside control. This allows an older spa control and incompatible legacy keypad to be upgraded together rather than attempting to reuse a discontinued topside.

The BP7 platform is also compatible with a variety of Balboa TP and SpaTouch interfaces when the appropriate model, software version and configuration are used.

Replacing an Older Balboa VS, GS, EL or ML System?

If your original Balboa spa control has been discontinued, the BP7 may provide a modern retrofit solution. Older Balboa systems were produced in many configurations, so the part number on the original control box is important when determining the correct replacement.

Whirly Bros is building an extensive cross-reference database for older Balboa spa controls to help identify the correct modern replacement system.

Why Upgrade to a Balboa BP7?

• Modern replacement option for many discontinued spa controls
• Genuine Balboa Water Group control system
• Multiple equipment configurations
• Supports complex multi-pump spa applications
• Modern Balboa TP-series topside interface
• Future access to commonly available Balboa replacement components
• Excellent retrofit platform for repairing older hot tubs

Installation Information

The BP7 is a configurable spa control system and is not a plug-and-play replacement for every spa. The correct setup, electrical configuration and equipment connections must be selected for the specific hot tub.

Installation should be performed by a qualified spa service technician or electrician familiar with spa control systems and applicable electrical requirements. Always follow Balboa installation instructions and applicable electrical codes.

Frequently Asked Questions

Will the Balboa BP7 replace my old VS control system?

The BP7 platform is designed to replace many older Balboa VS systems as well as GS, EL and ML systems. Compatibility must still be verified using the original control number and the equipment installed in the spa.

Does the G6505 include a topside keypad?

Yes. The Balboa G6505 is a BP7 retrofit kit paired with a TP500 topside control and 5.5kW heater.

Can the BP7 operate multiple spa pumps?

Yes. BP7 supports numerous equipment configurations, including multi-pump applications. The available outputs depend on the BP7 setup selected for the spa.

Can BP7 replace a spa control made by another manufacturer?

The BP7 platform can be used for many non-Balboa retrofit applications. However, the spa's pumps, heater requirements, accessories, electrical configuration and topside control must be evaluated before determining compatibility.

How do I know which BP7 configuration I need?

Start with the model and part number on the existing control box. It is also helpful to identify the number of pumps, pump speeds, circulation pump, blower, ozone system, lighting and other equipment connected to the control. Whirly Bros can help review this information before you order.
