Doesn't even have to be digital. My furnace, with a very old, very analog thermostat, has been randomly turning itself on.

- sokoloff 4y agoThat will often be a short in the thermostat wires; old thermostat tech worked by just dead-shorting the two "T" terminals together, so any degraded insulation could be calling for heat if it allows a short to develop. If it happens enough to be annoying, consider setting the T-stat to NOT call for heat and then go moving wires around until you find the place that has the intermittent short.
