Some homes have a furnace zone that is attached to the main breaker box and does not have a wire for the thermostat. This may be the case for your home. If this is the case for you, you will want to look into purchasing a thermostat extension cord to attach to the breaker box. You can find these at any home supply store or a hardware store that sells home appliances. Once you purchase the extension cord, you will simply hook it up to the thermostat inside the zone and be able to control the temperature of the house using this cord. With this, you will have a clean, constant temperature throughout the entire house, and it is also convenient to keep all of your appliances working on all settings.
There are a number of reasons why a furnace zone is not working properly. The first reason is when the wire that the zone uses has been damaged. This is a common problem that is fairly easy to fix. All you have to do is remove the existing wire from the zone and replace it with a new one that will work with the new wire that is attached to the thermostat. Before you do this, however, you want to be sure that the zone is switched off in order to prevent any water that is dripping down from the zone from dripping onto the wire and creating a short.
