In order to properly test and ensure that your system is functioning properly, we will place the system into a maximum airflow situation. In order to do so, simply follow the instructions below. 

 

  1. Place the 3-way switch or knob above the dehumidistat knob to the leftmost position
  2. Turn the dehumidistat knob to 20%
  3. Listen for the fan to accelerate in speed (gets louder)
  4. Turn the dehumidistat knob to 80%
  5. Listen for the fan to decelerate in speed (get quieter)
  6. Turn the knob back and forth between 20% and 80% a few times and listen near the knob for any clicks along the way.
