Balboa Controller GS501DZ 3KW Titanium Heater-55471

Product Description 

The Balboa GS501DZ Spa Controller is a reliable, industry‑standard control pack designed for single‑pump spa systems. It is a direct replacement for the Balboa GS501Z, with identical electronics, functionality, and software — the “DZ” suffix simply indicates the Australian / New Zealand compliant version.

Commonly used across a wide range of spa brands, the GS501 controller manages your spa’s heater, pump, ozone system, and topside control panel with Balboa’s proven reliability. This unit is ideal for spa repairs or upgrades where the original GS501 or GS501Z control pack has failed.

Supplied as a bare control pack, the GS501DZ is compatible with existing Balboa sensors, heaters, and topside panels, making it a straightforward replacement with no reprogramming required.

Fully interchangeable with GS501Z
AU/NZ electrical compliant
Trusted Balboa quality
