PRODUCT CONTENTS
PWM CONTROL FANS
The system utilizes high-performance DC-motors that are control using
PWM( Pulse Width Modulation) . This technology enables the dual fans to be able
to run smoothly at extremely low RPM speeds without generating motor or
electromagnetic noises. In addition, the fans feature a blade design with a high
static pressure rating, specialized for delivering airflow even in applications where
air movement is being restricted such as through duct work. The motor houses
allow the fan system to be mounted horizontally or vertically.
INSTALLATON
STEP1 :
Measure your fan vent to make sure this model will fit. Standard reference
mechanical dimensions.See the (Fig.0. & Fig.1.)
STEP 2:
Remove your fan grille. You may need to use a Philips screwdriver to remove the
mounting screws.See the (Fig.2.)
STEP 3:
Plug the power adapter into an outlet. This can be next to your register or inside
your register.See the (Fig.3.)
Fig.1.
Fig.2.

INTELLIGENT PROGRAMMING
The controller on each unit features active thermal monitoring that can trigger
fans to run for both cooling and heating temperatures you have set, as well as
automatically adjust fan speeds to respond to varying temperatures. The
controller can also be set to run continuously at speeds manually.
PROGRAMMING GUIDE
This in-depth guide will show you how to program the register booster fan,
featuring cooling and heating triggers that enhances airflow to improve your home
comfort. When programming your fan, it's important to note that the temperature
setting is the activation temperature. That is, it is NOT the temperature you want
your room to be; it triggers based on the airflow temperature coming through
your vents. The register vent booster fan does not adjust according to your
comfort level, nor does it adjust your central AC or heaters setting. Here is a
rundown of how the product works:
1. Your AC/ heater is on your preferred temperature setting.
2. Air blows through your duct, by the fan's probe, and out your register.
Fig.6.
Fig.7.

- 8 -
3. The probe reads the airflow temperature, activating the fan when a trigger is
tripped.
4. The register booster fan exhausts air from your duct to enhance AC/ heater
output.
5. will turn off when the probe detects a higher temperature than the cooling
trigger( lower temp. than the heating trigger).
We recommend establishing the two triggers one at a time to avoid confusion.
When both triggers are active, the vent booster fan can be activated by airflow in
temperatures not meant for your intended trigger For example, 67F may turn on
the fan via cooling trigger when you are just turning on your heater.
If you are using your air conditioner, turn off the heating trigger; if using your
heater, turn off the cooling trigger.
HOW TO PROGRAM
Follow these steps to calibrate your AC vent booster cooling trigger (skip to
heater):
1. Turn on your air conditioner.
2. Set it to a temperature you regularly use.
3. Let it run for a few minutes to let the fan system read a consistent temperature.
4. Press the mode button, then press the" UP Button " Button and “DOWN
Button”meantime, could switch the temperature unit between degrees Celsius( C)
and degrees Fahrenheit(F)
5. Press the mode button to navigate to the cooling trigger(snow- flake symbol).
6. Set the cooling trigger at or above the stabilized temperature indicated by the
temperature display mode.
To calibrate the air vent booster fan's heating trigger:
1. Turn on your heater.
2. Set it Lo a temperature you regularly use.
3. Let it run for a few minutes to let the AlRTAP read a consistent temperature
4. Press the mode button to navigate to the heating trigger( fire symbol). 5. Set the
heating trigger at or below the stabilized temperature indicated by the temperature
display mode.
6. Press the mode button to speed control mode( blade symbol) then press the
UP " DOWN fans speed could be adjust manually from 0 to 10.
