Madimack MJ Box Pump Interface / Controller for Pool Heat Pumps

The Madimack MJ Box Pump Interface/Controller is designed to optimize the operation of your pool's heat pump and circulation pump independently of the chlorinator. In standard pool setups, the filtration system operates on a set schedule, running both the pool pump and chlorinator simultaneously. However, maintaining the desired water temperature may require the heat pump to operate outside these scheduled times. Activating the pool pump without the MJ Box would also engage the chlorinator, potentially leading to over-chlorination. The MJ Box addresses this issue by allowing the heat pump to control the circulation pump directly, without triggering the chlorinator, thus preventing over-chlorination and ensuring efficient heating.
