Proportional Control The cycling effect associated with on/off control can be eliminated using proportional controls. In a proportional controller, the average power provided to the heater is reduced ...

On-off control is the simplest form of temperature control. All temperature controllers use a setpoint, which establishes the temperature at which a process is maintained.

ON/OFF control sufficed for early product generations, but consumers are now demanding that products are both capable and quiet. There are several speed fan control circuits that can be implemented ...
