I get all that - but what I don't understand is *where* the
hysteresis is built in? Is it in the computer? Is there a dial
that sets the temperature range of the hysteresis? Is there
a potentiometer?
The mercury switch provides some hysteresis.
How do we *change* or *set* how much hysteresis there is?
Specifically, how do I get *more* hysteresis in my furnace?
