EVERYDAY
OPERATION
The three lights provide feedback on humidifier operation.
Humidifying
When this light is on, it indicates the humidifier is
running.
Service
When this light is on, it indicates an operational fault
has occurred. Call an HVAC professional for repair.
Change Pad
When this light is on, it indicates that it is time to
change the humidifier pad. The light should not
be reset without changing the pad. Resetting the
Change Pad light without changing the pad could
compromise the humidifier. See “Replace the
humidifier pad” on the next page.
RESET
The RESET button is under the cover. This button
resets the timer that tracks when the humidifier pad
needs changing. When you change the pad, press the
RESET button.
The RESET button also clears a Service light. If the
Service light comes back on after you press the
RESET button, call an HVAC professional for repair.
