Older thermostats have two uncovered contacts. Since the temperature drops, a bimetallic strip bends, creating very first one particular electrical Get hold of and then A further. The system is thoroughly activated when the 2nd Make contact with closes, turning around the heating system as well as the anticipator around the thermostat.
You'll be able to go through our manual to the overall expenditures of furnace substitution if you think it would be time for a new one.
