CONTROL SYSTEMS APPLICATION GUIDELINES
APPLICATION GUIDELINES FOR THE BALBOA M-7 CONTROL SYSTEM he Balboa M-7 control is a revolutionary control system that provides additional reliability and ease of installation when compared to T conventional spa control systems. The software-based M-7 control system makes decisions based upon temperature and flow conditions that exist within the heater. The system operates properly if there is a minimum of 20 gpm flowing through the heater under all hydraulic variables and at worst case conditions.
APPLICATION GUIDELINES FOR THE BALBOA M-7 CONTROL SYSTEM Spa Design Guidelines For The M-7 Control System 1. The suction system for the 2-speed pump or for the circ pump must be dedicated. There must not be any other pumps connected to this suction system. 2. The suction system for the 2-speed pump or for the circ pump must include the following: A. 2 suction fittings, or B. 1 suction fitting and a skimmer. 3.
