am attempting to identify if a Trane XL1600 is considered a "Heat Pump" or "2-Stage
Heat Pump" ?

the unit does have 2 separate compressors

have read the owners manual (link XL16i (4TWX6) ) at
http://www.trane.com/Residential/Tra...rsManuals.aspx

..but don't see it mentioned anywhere

the reason I would need this is to tell my thermostat program (it asks for type of
Heat Pump and shows the two options "Heat Pump" or "2-Stage Heat Pump"

many thanks (posted in error initially to alt.hvac)
