The Price ECM speed controller is designed to interface with a high-efficiency Electronically Commutated Motor. 
 This low voltage speed controller offers either full manual dial control, automatic control (modulation signal from a terminal unit controller) or Building Automation System (BAS) control of the Electronically Commutated Motor.

Switching between the modes is easy: just apply the BAS signal and the controller will automatically switch over from manual (dial) mode to BAS mode,

- Low supply voltage (24VAC)
- Dual outputs to control up to two Electronically Commutated Motors (both motors will receive the same signal)
- Manual adjustment dial and front-facing voltage taps for voltmeter hookup eliminate the need to open the electrical enclosure
- BAS 2 to 10 VDC intput for variable speed remote control
- Front-facing Diagnostic LED light communicates control mode
