Balboa GS501SZ control system

This economical Balboa spa control system is a great option for retro-fitting older hot tubs if the original equipment has died. It uses Balboa's M7 technology which eliminates pressure switches or flow switches and uses Balboa temperature sensors. It has a built-in 3 kW heater.

It manages the following equipment:

• Pump 1 single or two-speed
• Circulation pump
• 1 blower (to replace this blower with a single-speed pump, use the GS504SZ instead)
• 1 ozonator
  Underwater lighting
• 1 sound system

The equipment connects to the control system using AMP plugs.

The system can be converted into a GS510SZ by adding a Balboa X-P231 expansions board.
