An analog thermostat, also called a mechanical thermostat, uses a bimetallic strip consisting of two metal strips. When the room temperature changes, it makes the metal expand or contract. As the metallic strips move, they open or close the circuit, which turns the unit on or off.
Certain analog thermostats control:
Analog, or mechanical, thermostats operate as the most basic type of thermostat. They typically only consist of a dial to adjust the temperature.
While Smart thermostats and programmable thermostats offer easy-to-read displays and more accurate temperature readings, they come equipped with many internal electrical components. Certain Smart thermostats even connect to Wi-Fi. Analog thermostats lack these electrical components, which means they face less opportunities to break. Additionally, analog thermostats typically offer a cheaper alternative than Smart or programmable options.
Single pole thermostats can set to a low setting, but cannot turn off. To shut the unit off, it must fully disconnect from the power source. Double pole thermostats can shut completely off.
