Been out of school too long - forgot +/- 1 and +/- 2 would be 2 & 4 degree swings respectively. That would make sense since my interior independent thermometer shows the fairly large swing of about 5 degrees.
Now, hopefully, I won't need the furnace until later in the year. But, I'll still check it. Also, this is the first time I've had to deal with the heat pump on the a/c. A little different.
