air distribution system.
PreRun and ShortRun are the periods of time when the the blower starts at very low CFM to minimize the
distributon of cool air in the system and then runs up to normal speed.
Off Delay is the time required to cool down the heat exchanger with low CFMs, to minimize cool draft in the

24 VAC input (R) to G, Y/Y2 and O (for cooling)
In Cooling - Dehumidification mode, with no 24 VAC input to DH, the CFMs are reduced by 15%.
The CFMs shown are reduced by 20% if there is 24 VAC input to Y1 (first stage cooling mode)
