The ECM-Infrared Remote Control System provides a means to remotely adjust
the output of ECM Motor. These are fractional horsepower fan motors featuring
an internal microprocessor to provide exceptional efficiency, performance and
motor life. Using the equipment manufacturer’s fan curve, the motor maintains
a constant airflow. The ECM-IRC allows adjustment of the airflow between the
manufacturer’s programmed minimum and maximum airflow. Adjustment is
achieved by setting an airflow index from 1-100 into the control.
A handheld remote control sends modulated infrared signals to a receiver on the
control. The control may be mounted on or near the equipment.
ECM Motor Infrared Control System
A flow index lamp flashes out the motor’s output, so instruments are not required
to adjust or record the air balance setting. A red status lamp indicates the motor is powered and turning.
Lamps and the infrared sensor may be mounted on the control, or remoted to accommodate a wide variety of equipment
configurations.
Operations
The IR sensor is mounted near the red status lamp. Point the
remote at the target (red lamp if the motor is on) on the equipment.
Operate the On/Off button or any of the four ↑/↑ buttons.
The green lamp near the target lights, indicating you are in an
adjustment session. Continue to operate the on/off button or
any of the four ↑/↑ buttons to achieve the desired settings.
Press the Enter button to save your new settings and exit the
adjustment session. Press the Clear button to delete your new
settings, revert to the original settings and exit the adjustment
session. If you enter an adjustment session and do not make
any adjustments for 15 minutes, the adjustment session automatically
clears. Use the Clear button to read the current settings.
Point the remote at the target and press the Clear button.
A green lamp begins to flash indicating the signal was received.
The flash sequence indicates the current flow index. The sequence
occurs in two sets. The tens (1st) set uses long flashes
to indicate the tens digit. The units (2nd) set uses short flashes
to indicate the units digit. An extra long flash in the tens set or the
units set indicates the value of the corresponding digit is zero.
Use the On/Off button to turn the motor on or off. Point
the remote at the target on the equipment and press the
on/off button. If you press Enter while the motor is off,
the motor stays off, even through a power on/off cycle.
Adjust the flow index using the ↑/↑ buttons. The ↑/↑ button pair
on the left adjusts the index ↑/↑ 10. The ↑/↑button pair on the
right adjusts the flow index ↑/↑1. Using the ↑/↑10 pair, you can
quickly move the index up and down. Using the ↑/↑1 pair, you
can precisely set the index to achieve the desired flow. During
an adjustment session, the green lamp blinks each time you
make a valid entry. If the flow index is already 100, and you
try to increase the flow index, the green lamp does not blink,
and the increase does not occur. If the flow index is at 91 and
you press the ↑10 button, the green lamp does not blink and
the increase does not occur because your entry would take
the index above 100. When the flow index is greater than 90,
use the ↑1 button to increase the index. The ↑1 and ↑10 keys
respond in a like manner when you try to set the flow index
below 1. (Zero is not a valid flow index).

Add an “en” suffix for the remote lamps/IR sensor.
Add a “T” suffix for terminal strip.
Testing
The EVO™/ECM-IRC controller provides a “GO” signal and a
“Vspd” signal to the ECM MotorTM. The “GO” signal is simple,
while the Vspd signal is complex. Both may be tested with a DC
voltmeter. Make sure the AC power is between 18 and 25 Vac.
Set the DC voltmeter to measure 25 Vdc. With the motor &
controller powered and connected:
Measure the voltage between GREEN pin 3 (negative) and
WHITE pin 15 (GO signal) of the ECM Motor connector. It should
be at least 9 Vdc. It may be as high as 25 Vdc, depending on the
length of the control wire and the number of connected motors.
Mounting
Wire as shown for remote mounting Mount the control inside a
metal junction box, control cabinet or enclosure. Make mounting,
lamp and IR sensor holes through the cover or enclosure wall
and mount the control to the inside. A standard electrical wall
plate may be used as a mounting plate, or mounting template.
The ECM Cable is factory fitted with a connector at each end.
The end connecting to the controller may be pulled through an
empty 3/4” conduit. Mount the controller with clearance for the
24 Vac power wires and control cable connector. Remote mount
the control in a single gang electrical switchbox. Use a standard
switch cover to cover the unit.
Wiring
Power the EVO™/ECM-IRC control with a 24 Vac NEC Class II
power source. Observe all code requirements regarding Class
II circuits to insure a safe, reliable installation. Connect the
neutral connection to the grounded side of the 24 Vac Class II
power source as required by code. Connect the 24Vac 50/60Hz
connection to the hot side of the 24 Vac Class II power source.
The control circuit design may interrupt the hot side power
source as a means to stop the ECM Motor. The control cable is
fitted with a 16 pin keyed connector. Fit this connector into the
mating socket on the ECM Motor. The other end is fitted with
a 4-pin connector. Fit this connector into the mating socket on
the edge of the EVO™/ECM-IRC controller. Plug the connector
in with the cable exiting away from the board. Be sure you are
lined up with the socket before pushing in the connector.
