Fan Filter Unit IOM
Installation & Operation

Infrared Speed Control (Optional)
The Flow-Set is a handheld infrared remote control configured to adjust the fan filter unit.
An EVO/ECM-IRC control sends the 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
Motor. (See Figure 10). Using the Flow-Set, you can turn the motor on/off, adjust the flow index from 1-100 and read the curren
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 IQ 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 units 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 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 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)
Batteries
Two AA batteries power the EVO/IRC-Handheld Controller. (See Figure 10). 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- Handheld Controller 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.
