I have a oil furnace and have recently replaced the older dial
thermostat with a digital thermostat. The problem I am having is that
at times the furnace will not turn off when the desired temp is
rached, ie, the thermostat is set at 68 but the furnace will run until
it is 74. I thought that maybe air from inside the walls was causing
the thermostat to read a different temp so i caulked the holes but am
still having the problem. Help!
I have seen new digital thermostats just
plain work bad. I have one in
my motorhome. It might just be one of
these bad designs. BTW, before
the Honeywell, at home, I bought a unit
that behaved just as you describe.
I called the company. They told me to
set the 'differential' to a lower
setting. It was already at the lowest
setting. The unit was just junk. I
returned it. The Honeywell I now have
works very well.
