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.
Chinese Hot Tub Upgrades
If you have a Chinese hot tub system that is running 3, 4 or 5 pumps then this is the system for you, its easy to plumb in with a little advice and is far superior to any Chinese system currently available on imported hot tubs.
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.
