Robert Shaw Solar Hot Water Automatic Reset Thermostat 50-70 Degrees ST1301
The Robertshaw solar auto reset enables your solar hot water system either flat plate or evacuated tubes to generate as much solar heated water as possible. It does this by "cutting out" the electric element booster so the sun can generate the hot water, when the sun goes down and you use the stored hot water the Robertshaw automatically resets and allows the boosted to function as a normal electric element.
