2. Next, check the FILTERSCAN WiFi Air Filter Monitor
power. Insure batteries or power to the Monitor is good (Status
LED blinks green approximately once per minute).
3. Turn power off to the FILTERSCAN WiFi Air Filter Monitor
power for one minute. Then turn power back on.
4. Turn power off to your wireless router for one minute. Then turn
power back on.
5. View your AirFilterSentry Notification Service subscription as
it may have expired.
If none of the above result in updated status data, please review
Table 1 WiFi Status indications above for various WiFi Status LED
conditions.
Can I install the FILTERSCAN WiFi Air Filter Monitor on a multi-
speed blower HVAC system?
Yes.
Where should I set the Service Filter knob?
At the recommended setting in the center of travel. This equates to
the doubling of the initial differential pressure to cause a clog alert.
If you want to waste energy, or think your filter is not dirty enough
when a clog alert occurs at the Recommended setting, you may turn
the Service Filter knob CCW toward “Less Often”. This increases the
differential pressure needed to cause a clog alert. Results? A more
dirty filter, more energy usage, and decreased IAQ.
If you want to save more energy at the expense of higher air filter
costs, or think your filter is too dirty when a clog alert occurs at the
Recommended setting, you may turn the Service Filter knob CW
toward “More Often”. This decreases the differential pressure needed
to cause a clog alert. Results? A cleaner filter, higher air filter costs,
less energy usage, and increased IAQ.
Overall, the Service Filter knob should be to set it at the
Recommended setting for the best balance between wasted energy
and higher air filter costs.
Model FS-245-C How is the conduit mechanically connected to the FILTERSCAN WiFi
Air Filter Monitor ?
There is a conduit connector knock-out located on the lower side of
the monitor housing.
What voltage is acceptable to power the FILTERSCAN WiFi Air Filter
Monitor via the conduit?
Typically 24V AC/DC, although an input voltage as low as 15V DC is
acceptable.
Model FS-245-B Do I have to install batteries if I power the Monitor from the optional AC
Adapter?
No.
Can I utilize both the AC Adapter and batteries for backup?
Yes, you can install batteries even though you also have an AC
adapter installed. Such power backup is unnecessary however
because the monitor’s non-volatile memory stores all operating
parameters in the event of a power failure.
