Infrared Speed Control (Optional)
The Flow-Set is a handheld infrared remote control
configured to adjust the Krueger CRFF-E and CRFF-E-
ARS units.
An EVO/ECM-IRC control sends the ECM motors a
FLOW INDEX and a GO signal. The motor sends back
a status signal that is connected to a red lamp. The
control includes an infrared remote receiver.
The Flow-Set handheld remote sends infrared remote
commands to the EVO/ECM-IRC control, allowing remote
adjustment of the ECM motor. Using the Flow-Set, you
can turn the motor ON/OFF, adjust the flow index from
1-100 and read the current settings.
Point the Flow-Set at the Flow-Set 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 Flow-Set 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 ECM 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 Flow-Set at the Flow-Set 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 unit’s
digit. An extra long flash in the tens set or the units set
indicates the value of the corresponding digit is zero.
• A flow index of 24 flashes two longs, then 4 short
• A flow index of 89 flashes 8 longs, then 9 short
• A flow index of 30 flashes 3 longs, then an extra lon
• A flow index of 04 flashes an extra long, then 4 shor
• A flow index of 100 flashes 10 longs, then an extra lon
Use the ON/OFF button to turn the motor on or off. Point
the Flow-Set at the Flow-Set target on the equipment and
press the ON/OFF button. If you press Enter while the
mo-tor 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 flo . 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 buttons, 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)

Two AA batteries power the EVO/IRC-Masters. Remove
the sliding door on the back of the unit to expose the
battery compartment. Remove the old batteries. Insert
the new batteries in the position indicated by the battery
pictures molded into the bottom of the battery
compartment. The battery spring clips are difficult, so you
may need to use a small screwdriver to “shoehorn” the
batteries into place.
For maximum battery life, store the EVO/IRC-Masters so
the buttons are not pressed. While current drain is
minimum when the unit is not sending infrared signals,
some battery current is drawn to sense the pressed key.
