GS510SZ Complete Control System

This system consists of a GS510SZ control box (3KW M7 Heater built inside), a VL700S touch panel.

Used to retrofit / upgrade any 2 pump hot tub systems.

Designed to connect and manage: 2 main pumps (1 x dual speed pump and a single speed or 2 single speed pumps and a circulation pump if required), an air blower, ozone, light and media (TV or Radio)

The Heater tube is 15" long and connects to 2" plumbing, seals and spare unions included.

The VL700S panel is complete with cable and includes 3m sticky on the rear to fit, face dimensions are 24.8cm x 7.9cm.

Cables and Fitting

Please note the control panel comes with a cable attached but this bundle is just the control panel and control box, you may need different connections to attach your pumps and parts to this control box.

Balboa control systems now use AMP connections directly on to the board, see related products for cables and connections, you will need 1 per pump or part that connects to the board.

For fitting instructions, please see the downloadable PDF manual on the manuals tab above.

Balboa M7 Technology

This system is made of M7 Technology which is a Balboa twin sensor control system, this means you don't need to drill a hole for a temperature thermostat, their is no pressure switch or high limit sensor, the system works by sensing the difference between the two thermostats, pre heater is the current temperature post heater is the hi limit and if both sensors are the same the element is working.

The M7 systems are great for upgrades on hot tubs because their so easy to fit into a system, this also applies if your building a hot tub from new.

Controller Upgrade
06 June 2018  | 

This controller upgrade was seamless; existing plumbing interfaced with no hitches, all cables connected directly to the motors (with colour for colour replacement), the DIP switch configuration was preset for a dual speed primary pump, even the control panel fitted directly in to the existing hole in the shell.
The unit was fitted in under 2 hours and the tub back to temperature and in operation the following morning.
Great service and support.
