am attempting to identify if a Trane XL1600 is considered a "Heat Pump" or
Heat Pump" ?
the unit does have 2 separate compressors
have read the owners manual (link XL16i (4TWX6) ) at
..but don't see it mentioned anywhere
the reason I would need this is to tell my thermostat program (it asks for type
Heat Pump and shows the two options "Heat Pump" or "2-Stage Heat Pump"
many thanks (posted in error initially to alt.hvac)
Its a two stage outdoor unit, and if you have electric backup, or other form
of backup heat, its a three stage.
If the outdoor unit is wired to bring both compressors online at the same
time, and have a form of backup heat, its only two stage.
no electric backup as I have year round temps above 15 Celsius (mostly at 30 C
it's wired to run first compressor for up to 30 min and then start 2nd
desired temp is not reached
also, the temp differential is set to 1 degree + 1 degree (ie. start unit-1 if
hotter by 1 degree than desired setting and run also unit-2 if 2 or more degrees
so, I suppose that answers it should be setup as 2-stage heat pump, thanks
