Temp rise is the temp difference of the return air and the supply air. This is normally measured across the furnace. It is not dependent on thermostat setting. Would be dependent on furnace operation.
I am a bit confused about what exactly "temp rise" is:
1) Is it the difference between the air inside the house and the air coming out of the furnace?
(If it's 65 in the house, and the temp rise is 30 degrees, does that mean the air coming out of the furnace should be 95 no matter what the thermostat is set to?)
2) or is it the difference between what the thermostat is set at and the air coming out of the furnace?
For example, if the temperature in the house is 65 and I want to bring it up to 75, and the temp rise is 30 degrees, does that mean the air coming out of the furnace should be 105?
3) Is the temp rise a fixed value that is set by an technician or does it vary by itself within the range listed in the specs - depending on gas pressure, etc?
Thank you for your help.

as above except the furnace needs to reach a steady state of operation. usually after 15 minutes of steady operation.
Nest is POO!!
