The Microsol II power differential solar heating controller has three temperature sensors that activate the water pump. It features a versatile switched-mode power supply (90-264 vac) and powerful relays (two 6A and one 30A) that directly command without the need of magnetic contactors, motors up to 1 hp, and electrical resistances up to 7,500W. The unit has two backup outputs, which can be electric, gas-powered, diesel-fired, and even set the swimming pool filtration. It offers features that prevent the water from freezing and overheating within the pipes and a clock with an internal battery to ensure the controller synchronism even in events where there’s a lack of energy. The Wall-Link is a remote interface, enabling easy and quick remote access. It can be used combined with Microsol II plus and Microsol II power.
