System Monitoring The STATUS LED will blink green approximately once per minute (called a
heartbeat) to indicate that the unit is functioning properly. Usually the
FILTERSCAN WiFi Air Filter Monitor will be in the standby mode,
conserving power. It wakes up periodically to monitor air filter condition,
battery level, and system operation. If no alarm conditions are detected,
the FILTERSCAN WiFi Air Filter Monitor goes back to sleep after
several minutes of monitoring.
NOTE: Should there be a power failure the FILTERSCAN WiFi Air
Filter Monitor will save all parameters such as the clean air filter
calibration and the current state of the air filter. When power is restored,
the FILTERSCAN WiFi Air Filter Monitor will continue operation with
no user action required. The same applies when replacing depleted
batteries.
Alarm Modes The FILTERSCAN WiFi Air Filter Monitor provides both audible and
visual local alarms indicating a clogged air filter, a low battery, or a system
malfunction. In addition, the AirFilterSentry Notification Service allows
remote monitoring* of system conditions. * Subscription to the AirFilterSentry
Notification service is required to enable this feature.
NOTE: The HVAC system blower fan must be running when the
FILTERSCAN WiFi Air Filter Monitor attempts to check air filter
condition. Since the FILTERSCAN WiFi Air Filter Monitor checks the
air filter condition periodically, it may take several days to detect, trigger,
and alert a clogged filter condition.
NOTE: The FILTERSCAN WiFi Air Filter Monitor has a light sensor
which prevents audible alarms when there is no light present at the Monitor
location. This prevents awaking occupants while sleeping and prevents
needless beeping in a crawl space, attic, or other unoccupied location.
The visual Status LED will still operate normally regardless of lighting
conditions.
Clogged Air Filter When the FILTERSCAN WiFi Air Filter Monitor detects a clogged air
filter, an alert condition is triggered. The red STATUS LED will illuminate,
blinking five times approximately every ten minutes until the alert condition
is reset. There will also be an audio alert which corresponds to the visual
alert indication. The clogged filter alert is reset by following the instructions
in the section "Calibrating When Installing a New Air Filter" below. In
addition, a text and or email will be sent to a designated person if you have
signed up for the AirFilterSentry Notification Service.
NOTE: A new or cleaned air filter should always be installed whenever the
CALIBRATE operation is performed.
Low Battery When the FILTERSCAN WiFi Air Filter Monitor detects a low battery
condition, an alert condition is triggered. The STATUS LED will blink
yellow approximately once per minute to indicate a low battery in the
Monitor. Replacing the Monitor batteries (see APPENDIX) will reset the
alert condition. In addition, a text and or email will be sent to a designated
person if you have signed up for the AirFilterSentry Notification Service.
