A thermostat is usually the device on the wall that senses and controls the temperature of the room. It does this by turning the system on and off till the proper temperature is achieved. For the thermostat to work properly it must be placed in an area of the room where the temperature will match what the human occupant will actually feel. Some thermostats have timers that can be programmed to adjust the temperature of the home at different times of the day. Thermostats have evolved a lot in the last few years and some can actually “learn” your habits and comfort levels, which I find kind of creepy actually. The furnace will come on automatically when the temperature at the thermostat registers below the setting you have selected. Once the furnace is on, setting the thermostat to a higher temperature will not heat the home faster. Adequacy of the system is determined by its ability to establish a temperature of 70 degrees F, as measured in the center of the room, 5 feet above the floor. In extremely cold temperatures (10 degrees below zero or colder), the system should be able to maintain a temperature differential of 80 degrees from the outside temperature.
- 1x per year: Thermostats are electronic devices that have batteries which need to be serviced from time to time. Thermostats are calibrated to within plus or minus 5 degrees.
- 1x per year: Vacuum any dust from around the thermostat.
