Balboa GS504SZ 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 patented M7 technology which eliminates pressure switches or flow switches and uses Balboa temperature sensors.
It can manage the following equipment:
- 24-hour circulation pump
- Pump 1 single or two-speed
- Pump 2 single-speed (to replace this pump with a blower, use a GS501SZ instead)
- Ozonator
- Underwater lighting
- Sound system
- Built-in 3 kW heater
The equipment connects to the control system using AMP plugs.
The GS504SZ can be converted to GS514SZ by adding a Balboa X-P231 expansions board.
