Balboa GS501DZ control system

The Balboa GS501DZ control system (as well as its rare cousin, the GS504DZ), is no longer manufactured, but the printed circuit board is still available as a spare part. If you need to replace the complete system (not just the motherboard), we advise you to install a BP6031G1, plus a compatible keypad.

The GS501DZ can control the following equipment:

• Circulation pump
• Pump 1 single or two-speed
• 1 blower (to replace this blower with a single-speed pump, use the GS504DZ instead)
• 1 ozonator
• 1 underwater lighting

Dimensions
Height: 268 mm
Width of box: 311 mm

Compatible keypads
Primary keypads, with screen: VL801D, VL802D

Power supply
The GS501DZ system is delivered pre-configured for a single-phase power supply. It can also be configured with a two-phase and three-phase power supply (for a distribution of the various units between the phases). If you have additional questions, please refer to the user's manual or contact us when placing your order, and we will take care of the configuration before sending the system.
You may also want to replace your cable gland if necessary!
