Most people grew up with an old fashioned rotary thermostat or a levered unit. These old gadgets used liquid mercury that acted as a conductor between wires that signaled to the furnace or air conditioning system to cycle. Advancements in heating and cooling technology have lead to the development of programmable thermostats. These control units are like a mini computer tied into a residential or commercial heating and cooling system.

How a Programmable Thermostat Works

A programmable thermostat runs like a mini computer. It has electronic switches and components that are wired directly to the heating and cooling system. The thermostat has a resistor that measures resistance from the thermistor and uses this information to calculate the indoor temperature. When the temperature reading differs from the set point of the thermostat, it signals to either the cooling system or the heating system to cycle until the set point is reached and there is no longer any resistance, at which time the system cycles off.

Functions of the Thermostat

Today’s digital thermostats perform many functions for indoor climate control.

  • Users can set a temperature for the heater to come on and a different temperature for the air conditioner to come on.
  • Scheduling options. Many programmable thermostats offer different scheduling options so that the home or building can be at different temperatures at different times of the day. Schedules can be set for an entire week, weekdays versus weekends or different every day.
  • A programmable thermostat is able to calculate the current temperature and the amount of time until the next scheduled temperature change so that the desired temperature is achieved at the desired time.

Advantages of Programmable Thermostats

A programmable thermostat can confer a significant amount of energy savings. By reducing the amount of heating or cooling that takes place when no one is inside the house or building, less energy is consumed by the heating and cooling system. The thermostats also feature system warnings to indicate home and business owners of the need for maintenance or repair.
