Is there a rule of thumb in choosing thermostat's deadband range. I
am using Totaline's definition of deadband (which is the difference
between the set point and when the heating (or cooling) goes on. If
the heating mode set point is 70 and the deadband is 2, the heat will
go on at 68 and turn off at 70. If in cooling mode, the cooling would
go on at 72 and turn off at 70.
I used to have it set at 1 degree and now have it at 2 degrees as my
furnace this was cycling on and off this past cold winter in the
My friend just had a new thermostat installed in PA and the contractor
set his deadband to 1 degree.
I'm just curious if there is a rule of thumb or some general cost
saving formula based on the deadband.
