A Smart Choice.

What better place to buy pump controls than from the people who make the pumps? Whether you're working on a Delta-P system or a Delta-T LoadMatch system, adding and setting up a SmartDrive+TSL is easy. There's no need for additional controllers, so you'll save on hardware as well. Perfect for secondary distribution pumps and constant speed primary pumps, our smart drives can set up the balancing for chillers and boilers, and even modulate secondary pumps and track system flow.

What does TSL do?

Taco System Logic controls the variable speed drive to optimize pump performance. Setpoints and controls are programmed at our factory to allow our pumps to run at much lower pressures than most industry professionals would consider. In addition, Taco Fault Tolerant Control maintains control even when the feedback signal wire is compromised. Pumping at much lower speeds will consume substantially less energy and require less maintenance, so along with peace of mind, you get superior efficiency, responsive comfort, and reduced life cycle costs all in one neat package. Add the SmartDrive +TSL option when you choose your next Taco pump.
