What is M7 Technology? In simple terms, the spa control box does not have a pressure switch installed in the heater manifold or any sensors wires that run outside of the box, everything is internal in one compact unit. Balboas Patented M7 Systems are the only controls in the industry that were designed without a pressure switch, the reason for the work around is that pressure switches are nuisance switches that can leak overtime creating problems to the sensitive circuitry in the control box. The design was to use two sensors that are balanced in resistance; one installed at each end of the heater manifold, that are constantly monitoring input/output values. If there is a significant resistance difference between the two the control system will display an error code detailing what the problem may be and the steps to troubleshoot. This control box is very easy to install and service. If you have any questions please e-mail us at [email protected].
Note: This control box has a brushed aluminum box enclosure. It has the same foot print and uses the same heater assembly as the Balboa VS Systems, it would be a direct drop in and a great alternative to the Balboa VS system.
If a 24 hour circulation pump is being installed, it must have no less than a 23 GPM flow. Laing, Grundfos or Waterway Tiny Might pumps do not perform at this rate and cannot be used. The Aqua Flo Circ- Master is a good choice (linked below)
