Details

When a spa control pack begins to fail, the effects show up everywhere. Heating may become inconsistent, pumps may not behave the way they should, and the whole spa can start to feel less dependable than it once was. This BP100G2 control system is designed to restore central control in compatible two-pump setups that use a 4.0kW heater.

With support for Pump 1 and Pump 2, this system is intended for spas that need more than basic single-pump control. That makes proper replacement especially important because the pack has to coordinate multiple pieces of equipment smoothly instead of simply powering one function at a time.

The included 4.0kW heater pairing keeps the package aligned with systems built around that output level, which helps make the repair more complete and reduces the need to source mismatched components separately.

Once installed in the right spa, this control system helps restore a more organized, reliable operating rhythm, bringing pumps and heating back into sync and making the spa easier to trust every day.

Paired with a 4.0kW heater for a more complete replacement solution
Helps restore coordination between heating and pump functions
Useful when the original control pack becomes unreliable
Supports a steadier and more dependable spa experience
