eCm speed Controller - deluxe, standard
Price DELUXE ECM Speed
Controller
The Price Deluxe ECM speed controller
works with a high efficiency ECM motor.
This low voltage (24VAC) speed control
allows full manual (push button adjust)
or BAS (2-10VDC signal) control of the
ECM motor.
Features:
• Dual outputs for controlling 2 ECM motors (Note:
Both motors will receive the same signal.)
• Red three-digit digital display for reading out:
–
Speed 0-100%
–
Motor RPM (for motor number one only)
–
BAS input voltage (Digital readout of incoming BAS voltage signal.)
• Building Automation System input (2-10VDC)
for remote control
• 0-10 VDC output corresponding to motor RPM.
LED Digital Display
The Digital Display shows the user several modes of operation. This allows for easier
and more precise field adjustment and troubleshooting.
By pressing both the UP and DOWN push buttons at the same time the user can
cycle between the following modes:
1. Speed Adjustment – is easier and more precise with the digital display and push
buttons than with a standard dial.
2. Motor RPM – displays the real time motor speed to aid in troubleshooting.
3. BAS input voltage – displays the input voltage signal from the building
automation system (BAS). Note: Any BAS voltage signal above 1 VDC overrides
local speed control.
Important Information regarding the ECM motor.
Do not switch 120/208/240/277 VAC power to turn ECM motor on and off. Instead
control the 24VAC signal or BAS signal to turn the ECM motor on and off. The
ECM motor has large capacitors that charge quickly on mains power up. Switching
on several motors frequently could reduce building power quality and is not
recommended.

Standard ECM Speed Controller
The Price standard speed controller allows manual adjustment of the fan flow using
the adjustment dial on the control board and a voltmeter. Remote control of the fan
speed is also possible with the BAS input. The following chart describes the controller
