In C ooling - Dehumidification mode, w ith no 24 VAC input to DH , the CFMs are reduced by 15% .
The CFM s shown are reduced by 20% if there is 24 V AC input to Y 1 (first stage cooling mode)

P reR un and S hortRun are the periods of time when the the blow er 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 dow n the heat exchanger w ith low CFM s, to minimize cool draft in the
air distribution system.
