Global Series Controls

Next Generation of Entry Level Hot Tub Control Systems

The Global Series (GS) family of hot tub control systems were designed using Balboa’s patented M7 temperature and flow sensor technology and a new universal control platform. These features increase the reliability, ease of installation and serviceability of the control.

Designed for Easy Installation and Service

The GS family is based on a common universal control platform, which increases feature flexibility while reducing installation and configuration problems The GS family has exceptionally good feature flexibilities, so its performance is competitive with much higher-end products. The units incorporate Balboa’s patented M7 temperature probe technology, which eliminates the more failure prone pressure switches and simplifies the installation process by not having to drill additional holes in the spa.

Flexible, High Reliability, Feature Rich

The systems have a plastic enclosure to eliminate water intrusion. Connectors are built on to the circuit board minimizing wires and simplifying service. The different models have controls for a single two-speed pump or an additional blower or pump. All models feature a power supply that is wired for 230 volts, a 1.0, 2.0, 3.0 Kw heater and support mini, duplex or serial standard panels.
