ACT D'MAND KONTROLS C3 Series Hot Water Recirculation Pumps

ACT Inc. pumps deliver hot water on demand, reduce water waste, and conserve energy. The D'MAND Kontrols® Recirculating Hot Water Pumps send cold water in the plumbing line back to the hot water heater, via the cold water or dedicated return line, while simultaneously bringing hot water to all fixtures on that plumbing line, in a matter of seconds. Unlike other hot water recirculation pumps, the D'MAND Kontrols® System does not allow hot water into the cold water line, and delivers hot water to the furthest fixtures on-demand, rather than on a timer based system.

The C3-100 includes an electronic circuit board, thermosensor mounted in composite volute, 3/4" CPVC threaded connections, and internal check valve. 5 year warranty on pumps, 1 year on controls.

C3-100: Recommended for use with dedicated return lines in buildings up to 4,000 sq. ft. with tank water heaters, or pipe runs up to 120 lineal ft. with tankless water heaters.

C3-100-PFS: Recommended for use with standard plumbing (retrofit) in buildings up to 4,000 sq. ft. with tank water heaters, or pipe runs up to 120 lineal ft. with tankless water heaters.

How it Works

standard plumbing KONTROL system

At the push of a button, the ACT, Inc. Hot Water D'MAND Kontrol Systems® circulate the ambient temperature water in the hot water lines (water that is normally lost down the drain) back to the water heater. This occurs up to 80% faster than just letting the water run down the drain—the usual scenario. Depending on the plumbing layout, the route and time can vary. The D'MAND Kontrol Systems® move the water rapidly, so that the hot water arrives at the fixtures before the heat is lost through the pipe.

As the ambient temperature water in the cold water line travels towards the water heater, the D'MAND Kontrol Systems® fill the hot water line with hot water. When the hot water reaches the D'MAND Kontrol Systems®, a thermal sensor (thermister) senses a temperature rise and quickly shuts the pump off. The sophisticated electronic circuitry that does this is attached to the high-performance pump housing.

ACT Metlund KONTROL SYSTEM

This results in getting hot water to the fixtures three to four times faster (on average), greater convenience in not having to wait, a savings in water and energy, and a reduction in sewage costs! As a by-product of these savings, a cumulative result is the improvement of air quality.

The D'MAND Kontrol Systems® can utilize the cold water line as a return line or it can use a dedicated return line. By using the existing cold water line, it is easy to retrofit existing homes or businesses. Special plumbing is not needed, and since the System will not allow for hot water to cross over to the cold water line, all the cold water fixtures still have cold water.

#1 Q:   Once the system has been activated and then shut off by the thermistor, is there a timer to prevent the pump from reactivating again until it is requested by pressing the pump activation switch (button)?
A:   The pump will only start/re-start when the button is pressed or the motion sensor methods trigger it. If the thermistor still reads hot, the pump will not run or non run for very long.
