The manual says the following:
"Window Efficiency: The humidifier frost control setting uses this efficiency rating to compute the humidity set point within the range of 15% to 50%. Values are from 1 to 7, with 7 being for the most efficient windows possible."
What does "most efficient windows" mean? Does anyone know the algorithm behind this?
I'm assuming this means the target humidity is adjusted based on outdoor temp, can anyone confirm or deny this?
