If you have a Home+ plan and are signing up and configuring more than one monitor, press the “Add
Monitor” button on the Home page and provide the information for the additional monitor(s). You are
now done.
For more detailed instructions on how to sign up and configure your monitor on the AirFilterSentry
website, consult the FILTERSCAN WiFi Installation and Reference Manual.
STEP 2: CONNECT TO THE AIRFILTERSENTRY CLOUD SERVER
Remove the front cover of the monitor by pressing on the sides of the housing. The inside of the
monitor is shown below.
Using proper electrical conduit, connect the monitor to the HVAC system’s auxiliary 15-24V AC or DC
power supply. Consult the picture above for the location of the AC/DC power terminals. This should
ONLY be done by a licensed electrician or HVAC technician. WARNING! Failure to follow all
instructions may result in electrical shock and serious personal injury. When you do, a number of LED's
on the monitor’s printed circuit board will start to blink. Wait about one minute until the blinking has
stopped. There will be a red LED on at the upper right in the figure above, and a green LED on at the
lower right in the figure above.
Determine whether your router has a WPS button and where it is located on your router. If your router
does not have a WPS button, you will need to connect the monitor to the AirFilterSentry server using
the procedure found in the Section “Connecting Your FILTERSCAN WiFi Air Filter Monitor with your
Wireless Router without a WPS Button” in the Installation and Reference Guide. Once you complete
that procedure, skip to Step 3 below.
Depress the WPS button on your wireless router and hold it for two to ten seconds, until its LED
begins to blink.
Using a pencil, toothpick, or other non-metallic object, depress the Monitor WPS button (see the figure
above) just once until you feel it “click” and immediately release it. The WiFi Status Indicator will start
blinking green, then amber, and then green again. If the WiFi Status Indicator only blinks green or
amber before it goes off, and never blinks red, it has successfully paired with your router. You can now
go to Step 3.
