We noticed the humidity went down to 30% and I adjusted the rate to increase Now our Aprilaire 400 says to change the filter. I did that, and it still says to change the filter. The furnace runs fine. What do I do now?

If your humidifier is equipped with a Digital Humidifier Control with Water
Panel change indicator, after replacing the Water Panel, turn the control
knob to the "Test/Reset" position until the "Humidifier On" light blinks to
reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure
to turn the control knob back to it's original setting. If the "Humidifier On"
light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.
