This system consists of a GS100 control box, 2kW Heater and a VL200 mini control Panel (11cm x 4cm) .
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.
