Thank for contacting us and this is a combined response to your two posts above. First we do not offer an electronic control or aqua-stat that will control a domestic water re-circulation pump. We take a different approach and i would refer you to our Idronics issue 21 on "Recirculating Domestic Hot Water Systems". As you design your domestic re-circulation system we offer a lot of products for example our 6000 Legio-Mix electronic mixing valve to control domestic water outlet temperatures at the point of distribution and has 100% close off to eliminate creep. You describe your project as a multi story building. We have options for balancing domestic water circuits or branch runs. Our 116 ThermoSetter for example would provide thermostatic balancing to the branch circuits to ensure to increase the speed of hot water delivery, reduce water waste and save pump energy. The above options with today's energy efficient pumps may be a great solution. I would always encourage you to reference our Idronics or you can see our "Coffee with Caleffi" webinars on YouTube. We have webinars on there that relate to domestic water recirculation. You can access either of the two through the "Education" tab on our website.
