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

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 ECMs (both motors will receive the same signal)
- BAS 2 to 10 VDC input for variable speed remote control
- Red four-digit display communicates:
... Speed: 0-100%
... Motor RPM: for one of two motor inputs
... BAS Input Voltage Display: incoming BAS voltage signal
