It is easy to do to increase speed. It is .2 the recommended SP for cooling, but can very alittle just will get noisier.
Re configure go into install and set up Zones or duct assessment. You can limit flow to low medium or max with no limits. in which will reduce blower RPM. Their is alot this stat does and After 3 years Im still learning. I install lots of these controllers every year.
Every 24 or 48 hours furnace does a duct assessment for damper limits. I think I am sure on this but might be wrong.
