GS501Z Complete Control System

This system consists of a GS501Z control box with fitted M7 Heater (3kW Heater), a VL404 control Panel.

Used to retrofit / upgrade any 1 pump hot tub systems that also needs an air blower.

Designed to connect and manage: 1 main dual speed pump and a 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 panel is complete with cable and includes 3m sticky on the rear to fit, face dimensions are 18.7cm x 8.3cm.

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.

I had several Spa items needing maintenance and upgrades one of my first item was to purchase a Balboa GS501Z complete with VL404 touch pad. Dispatch and delivery was as promised, The units where in good order. There was no operating manuals as such, however, the sheet of information (schematics) provided was sufficient to plug and play the devices. The unit will be put into service within the next few days. thanks to Jon P for his help
