The M7 technology means you do not need to have sensors and flow switches going back into the tub as everything is done inside the control box by 2 sensors.
With the addition of an expander board you can add an additional 1-speed pump or an additional blower.
This control box is very versatile and enables you to run multiple topside controls and auxiliary buttons.
This is a generic unlicensed control box. This unit must be fitted by a competent individual or tradesman. Incorrect installation could invalidate the warranty.
