Description
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:
a) Speed 0-100%
b) Motor RPM (for motor number 1 only)
c) BAS input voltage (Digital readout of
incoming BAS voltage signal.)
- Building Automation System input
(2-10VDC) for remote control
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. |

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 24 VAC polarity.***
Analog RPM Output Signal
A two wire connection supplies an analog (0-
10VDC) signal that is directly proportional.
The range is 0 – 1500 RPM and it will output
a proportional 0 – 10 VDC 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. Formula for outputs below
(tolerance ± 10%):
- VDC output = (RPM / 150)
- RPM = (VDC * 150)
- Output signal: 0 – 10 VDC @ 20k ohm
minimum input impedance and is short
circuit protected. (Output impedance is 511
ohm to protect against incorrect wiring)

BAS Input Signal
The BAS input signal overrides the local set-point using a remote 0 – 10 VDC signal. If the
BAS signal drops below 1 VDC local control (via the push buttons) is restored.
