Replacing a manual thermometer with a digital one can save on energy costs.
Due to rising energy costs, many homeowners are choosing to replace their old manual thermostats with newer programmable digital thermostats. Experts estimate that the decision to upgrade a thermostat can save the homeowner up to 35% in energy costs per year. Instead of maintaining a constant temperature for 24/7 like a manual thermostat, a digital thermostat can be set to turn off during the day when the family is at work or school and to turn on when they get home. . Different programs can also be set for weekends and nights. Replacing a thermostat is usually not very difficult and only requires a few common tools.
Thermometer power needs to be turned off before starting work.
When purchasing a replacement thermostat, the homeowner must confirm that the new one is compatible with the home’s heating and cooling system. While many people choose to replace their thermostat with a digital model, manual styles are available and are cheaper. Most electrical clerks at your local hardware store can help you make this choice. The only tools needed are a standard screwdriver, a drill, a level and some masking tape. For safety, many experts recommend wearing protective eyewear when changing a thermostat.

As with any electrical project, the homeowner should always turn off the power first to avoid a shock. Although the wires in a thermostat are low voltage, it is advisable to turn off the power before touching any wires. This can be done in the fuse box or circuit breaker, or a switch can be located around the heating and cooling unit. If the circuit breakers are not individually marked, the homeowner may need to turn off power to the entire house.
The following is a list of step-by-step instructions on how to change a thermostat:
The owner must remove the thermostat cover. Using masking tape, she should label the wires according to the location of the screw terminals and then remove the wires from the screws. She can then unscrew the thermostat body to remove it from the wall, making sure the wires don’t fall behind the wall during this step. New mounting holes for the new thermostat can be marked by holding the base and marking the holes with a pencil. Once this is done, the owner must drill the new holes. She must then run the wires through the base of the new thermostat and connect them to the terminals on the base. When doing this, she should pay close attention to the wiring instructions or diagram of the new thermostat, as the color coding may not match from the old thermostat to the new one. The homeowner can then install the thermostat body into the base and make sure to install new batteries if needed. Power can then be restored.
A thermostat can control central heating systems such as boiler systems.
When a homeowner decides to replace a thermostat, he or she is taking the first step in upgrading an important home system. This is a relatively simple home repair, but as with any electrical job, if it becomes excessive or messy, an electrician can always be called in to finish the job. Once the job is done, many older thermostats have mercury switches, making them hazardous waste. They must be disposed of properly, in accordance with city regulations.
