SAFETY This model product should only be installed by a licensed electrician.
1. This model is powered from the HVAC system’s auxiliary 15 to 24 VAC/DC power supply and should
be installed by a qualified electrician. A typical installation will have that power run through an installer-
provided conduit to the FILTERSCAN WiFi Air Filter Monitor .
2. Locate the six terminals on the left-hand bottom corner of the printed circuit board illustrated in
Figure10. Connect 15 to 24V AC or DC to the 1
st
and 3
rd
leftmost terminals as shown. The 2
nd
leftmost
terminal is for earth ground connection, if available.
3. The three terminals on the rightmost terminals are for connecting the optional dry contact relay output.
Reference Figure 21 in the APPENDIX.
4. When power is applied, the beeper should sound momentarily and the STATUS LED should come on
green momentarily, then turn on and remain red. This indicates that the unit has not yet been
calibrated to the air filter and HVAC system upon which it is installed. Additionally, the WiFi Status LED
will blink a series of Red and Green. Wait until all blinking has stopped.
