It supplies the circulation pump when either calls for it, allowing each system to follow its own schedule.

The installation manual specifies a \u003cstrong\u003emaximum pump rating of 1.5HP (8A)\u003c\/strong\u003e. Check the pump's rating plate and the heater's control connection before purchase.\u003c\/p\u003e\n\u003cp\u003eThe heat pump connection and commissioning must follow the manuals for both units. Mount upright in a sheltered position. Only the circulation pump supplying the heat pump connects to the MJ Box outlet.\u003c\/p\u003e\n\u003ch2\u003eProduct details\u003c\/h2\u003e\n\u003cdiv class=\"table-wrapper\" style=\"overflow-x:auto;\"\u003e\u003ctable class=\"table\" style=\"width:100%;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;white-space:normal;\"\u003eProduct type\u003c\/th\u003e\n\u003ctd style=\"white-space:normal;\"\u003eSingle pump heat demand interface controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;white-space:normal;\"\u003eManufacturer code\u003c\/th\u003e\n\u003ctd style=\"white-space:normal;\"\u003eMJBOX400\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;white-space:normal;\"\u003eSupply connection\u003c\/th\u003e\n\u003ctd style=\"white-space:normal;\"\u003e240V mains; 10A plug version\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;white-space:normal;\"\u003eMaximum connected pump\u003c\/th\u003e\n\u003ctd style=\"white-space:normal;\"\u003e1.5HP (8A), per installation manual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;white-space:normal;\"\u003eControl connection\u003c\/th\u003e\n\u003ctd style=\"white-space:normal;\"\u003eLow-voltage heat pump control cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\" style=\"text-align:left;white-space:normal;\"\u003eStatus indicators\u003c\/th\u003e\n\u003ctd style=\"white-space:normal;\"\u003ePower, chlorinator and heat pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003c\/div\u003e\n\u003ch2\u003eCommon questions\u003c\/h2\u003e\n\u003ch3\u003eDoes the MJ Box change pump speed?\u003c\/h3\u003e\n\u003cp\u003eNo. It switches circulation in response to demand; it does not convert a single-speed pump to variable speed.\u003c\/p\u003e\n\u003ch3\u003eDoes it add Wi-Fi to my heater?\u003c\/h3\u003e\n\u003cp\u003eNo. Any app control or heating schedule comes from the compatible heat pump and its controls.\u003c\/p\u003e\n\u003ch3\u003eWill I still need enough water flow?\u003c\/h3\u003e\n\u003cp\u003eYes.
