However, to maintain your desired pool water temperature, a pool heat pump may need to run outside these scheduled filtration hours.\u003c\/p\u003e\n\u003cp data-start=\"711\" data-end=\"968\"\u003eThe MJ Box solves this issue by enabling the heat pump to call for water flow using the “demand heat” function. This allows the pool pump to run only when heating is required, while keeping the chlorinator switched off, preventing excessive chlorine dosing.\u003c\/p\u003e\n\u003cp data-start=\"970\" data-end=\"1131\"\u003eIdeal for use with Madimack heat pumps, the MJ Box improves heating efficiency, protects water balance, and provides smarter control of your pool heating system.\u003c\/p\u003e","brand":"Madimack","offers":[{"title":"Default Title","offer_id":47382424551645,"sku":"MJBOX400","price":499.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0654\/8131\/0429\/files\/Madimack_Heat_Demand_Controller_MJ_Box.png?v=1770773603","url":"https:\/\/myonlinepoolshop.com.au\/products\/madimack-heat-demand-controller-mj-box","provider":"My Online Pool Shop","version":"1.0","type":"link"}
