1. If the furnace responds somehow, then it's the furnace. If it doesn't, it could still be.

If the only demand is coming from the thermostat, then any activity on the part of the furnace means it got the signal from the thermostat. If you have a combined system where you get heat and hot water from the same unit, then the hot water demand could cause it to turn on.

Easiest test is to make sure the furnace isn't doing anything, and then crank the thermostat all the way up.

If the furnace keeps doing nothing, it is either the thermostat or the furnace. If the furnace does something, it's the furnace that has the problem.
