Part 5/8:
This basic on-off mechanism establishes the temperature regulation without a complex interaction to control the heat output directly. Instead, it can manage temperature effectively through time-based operations, cycling the system on and off to maintain comfortable levels.
Basic Thermostat Variants
Among the simplest thermostats are the bimetallic strip types. These utilize a coil made of two different metals that react to temperature changes. As the temperature decreases, the coil tightens, leading to the closure of contacts that command the furnace to heat. A magnet plays a crucial role—preventing rapid cycling by ensuring that the contacts remain connected until the surrounding air temperature rises significantly.
