(Balboa Retrofit Kit 4.2) Balboa GS510DZ + VL801D


Only 1 left in stock


This Balboa GS510DZ spa control box bundle benefits from having a 3kw heater and a high-quality VL801D deluxe touch panel which is ideal for fitting over spa shell holes from other removed panels due to its size. The GS510DZ control box will operate a two-pump and air blower hot tub system but can also operate a three-pump system if no air blower is used. 

This Balboa bundle can also be used for upgrading from a Chinese spa control system or updating an old unserviceable one where parts are unobtainable.

Due to this system having a 3kw heater and being able to run this many electrical components, you will need to have a 32 amp supply to it from your home consumer unit so you may need an electrician to wire this for you if you don’t already have this installed.

This bundle can operate:

  • Pump 1 – Two Speed (One speed if using circulation pump)
  • Pump 2 – One Speed
  • Pump 3 or Air Blower – One Speed
  • Circulation pump – Optional
  • 12 Volt light (on/off)
  • 3kw M7 heater

Balboa’s M7 Technology

The latest Balboa GS & GL control boxes all come with M7 technology, so you don’t need to integrate external temperature sensors into the spa or pressure switches to determine water flow. In this technology, two M7 sensors are employed, one at each end of the heater assembly, which provide a superior method to detect water flow and temperature at the same time.
