Part 6/8:

This mechanism is effective in regulating heating but does not add complexity to the control system. In scenarios with advanced heating or cooling systems, additional wires and features may be present to manage them effectively, but most domestic setups operate within this basic framework.

Modern Developments: Digital Thermostats

The introduction of digital thermostats has modernized home heating and cooling management. These devices often contain microprocessors that can engage a relay to command the operation of heating or cooling systems based on pre-set temperature thresholds. They require a power source, often supplied through a common wire (C wire), which allows them to function persistently without depending solely on the circuit they command.
