When you call in with a tech support issue we will want to know which version of our control board is controlling your unit. This is important because it will help us properly diagnose what is going on with your WHF. In most cases we can determine the control board version if you give us the model information for your AirScape. The model is listed on a sticker found on the unit (near the junction box on the 1.7, 2.5, 4.5 and on the damper door of the 1.0). Occasionally the model sticker isn’t enough. If you are already going into the attic to write down the model information you might as well take a look at the control board as well.
The control board has had several different incarnations over the years. Please take a look at the photos below and identify your control board before you call tech support.
My control board looks most like: 1, 2, 3, 4, 5 or 6 (Differences between 3 and 4 circled in red)
