Hi, I recently had installed an TWE031E13F (31,000 btu) Trane variable speed air handler (AC only)with a Trane XL14i 2.5 ton compressor. It is great, but I needed to know if anyone who is familar with the Dip switches in the air handler can tell me if the factory setting of switches 1-4 (which control blower speed based on tonnage size according to the manual), in the all OFF position is optimal for my tonnage? The manual says to look on the label on the blower housing,but the service panel is on and I dont want to disturb it if I dont have to. I think the installer said he left switchs 1-4 all off (factory setting), but I want to be sure that is where they belong for a 2.5 ton system. Thanks in advance for any info.Great message board by the way.
