Option 40 — Humidify Fan
This selection controls whether humidification can only be done when a heating
demand is present. If the homeowner turns humidification OFF, this
configuration operates as if the selection was set to OFF.

Option 41 — Variable Speed Blower
This selection allows the installer to select between a single speed or variable
motor. In a system with a two speed compressor (A2, h2, H2), if a
dehumidification demand exists and the compressor is energized for cool to
dehumidify, cooling, or both, and the system has a PSC blower (Option 41 =
OFF), then both Y/Y2 and Y1/W2 are energized.
