General
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.

If E001 is displayed – no RPM pulses are being read. Check 6 position cable.
If E002 is displayed – RPM reading is over 2000 RPM. Check primary air.

LED Digital Display
The Digital Display shows the user several modes of operation. This allows for easier and more precise field adjustment and
troubleshooting. To change modes press both up and down buttons at the same time.
NOTE: Local setpoints are stored to EEPROM and will remain set after power failures.
WARNING: 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.

Low Voltage Wiring
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.
NOTE: 24VAC COM, BAS COM, ANALOG OUTPUT COM are all connected together. Please observe 24VAC polarity
BAS Input Signal
The BAS input signal overrides the local setpoint using a remote 0 – 10VDC signal. If the BAS signal drops below 1VDC local
control (via the push buttons) is restored.

BAS Voltage Response Notes
0-1VDC Local Control mode using push buttons Local setpoint can be adjusted from 0 – 100 (%) using push
buttons
1-2VDC Motor Off Recommend sending a 1.5VDC signal to command motor off
2-9VDC Modulating Control 2 – 9VDC modulates motor from 0-100%
9-10VDC Maximum Speed Motor is running at maximum speed. (100%)

Analog RPM Output Signal
A two wire connection supplies an
analog (0-10VDC) signal that is directly
proportional to the MOTOR 1 RPM.
The range is 0 – 1500 RPM and it will
output a proportional 0 – 10VDC signal.
If a dual blower system is used only the
RPM from motor 1 can be read.
NOTE: The minimum speed of the ECM
motor is approximately 250 RPM.
