Nidec EcoTech EZ Variable Speed Motor
The EcoTech EZ motor/control is a programmable, high efficiency pool pump motor designed to be an easy, drop-in field replacement that can be wired with minimal or no modifications.
Increased demand on the power grid, rising energy costs and environmental concerns have prompted many states to enact legislation requiring the use of more energy efficient pool motor products. Unlike the traditional pool pump motor, the energy saving, easily programmable EcoTech EZ motor/control can reach efficiency levels of up to 90 percent and help reduce energy costs! Its brushless permanent magnet motor, control, and user interface
all work together to provide an efficient, easy-to-use alternative to existing induction motors. And, with an approximate one-year payback (depending on energy costs in your area) and continued savings throughout the life of the motor, EcoTech EZ motor/control is an excellent choice.
Each EcoTech EZ motor/control is factory programmed for out-of-the-box functionality, or can be re-programmed for 2-3 different flow rates per day. In addition, by using the integrated User Interface, the motor can be programmed for up to four "custom flows" to run water features, cleaning spa jets and other pool features or accessories. Simply program the motor to maximize energy savings. Set it once and enjoy the savings. There's no need to continually reset the program.

The interface adapter marries the EcoTech EZ with your pool automation control system, giving the control system command over the Variable Speed Motor. The motor comes standard with a RS-485 port and the interface
adapter can be purchased separately.
Installations are easy with the top-down visible terminal board with quick connect or screw head connections. Installation is easy. Simply bring in the two power leads to the terminal board and then attach the ground lead to the green ground screw located near the terminal board.
The freeze sensor mounted inside the control. If the control is enabled (on), the sensor will detect temperatures below 40 degrees Fahrenheit and run the motor on low speed 30 minutes on and 30 minutes off until the temperature rises above 40 degrees F.
Because the motors doesn't use switching mechanisms, motor noise is minimal, especially when the motor is programmed for low flow rates. The ability to program the EcoTech EZ motor/control for lower speed operation Increases the efficiency of the pool's filtration process and minimizes the motor noise and the hydraulic sounds created by the pump.
The motor is a Totally Enclosed Fan Cooled (TEFC) motor. TEFC construction adds an important line of defense against motor failure because there are no ventilation openings. This design helps prevent the intrusion of rain, dust, bugs, rodents and other contaminants into the motor. The controller is mounted in an enclosure to help prevent damage from foreign contaminants.
