Installation Guide

cause the FILTERSCAN WiFi Home Air Filter Monitor to issue an alarm at a lower level of filter

clogging (less energy consumption). Turning the SERVICE FILTER adjustment knob counter-clockwise

will cause the FILTERSCAN WiFi Home Air Filter Monitor to issue an alarm at a higher level of filter

clogging (more energy consumption). See the FAQ Section for further information.

Operation - FILTERSCAN WiFi Home Air Filter

Monitor

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 Home 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 Home Air Filter Monitor goes back

to sleep after several minutes of monitoring.

NOTE: Should there be a power failure the FILTERSCAN WiFi Home

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 Home Air Filter Monitor will continue

operation with no user action required. The same applies when replacing

depleted batteries.

Alarm Modes The FILTERSCAN WiFi Home 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. *Creating an

account in the AirFilterSentry Notification service is required to enable this feature.

NOTE: The HVAC system blower fan must be running when the

FILTERSCAN WiFi Home Air Filter Monitor attempts to check air

filter condition. Since the FILTERSCAN WiFi Home 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 Home 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 Home 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. NOTE: Allowing this alarm

condition to go on indefinitely will drain the batteries (-B model only). 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 (depressing the Reset button) operation is performed.
