Drivers “Everything / Nothing” are the most basic control systems. They send an activation signal (“On”, “Ignition”) cuando la entrada de señal es menor que un nivel de referencia definido previamente y desactiva la Output signal (“Not”, “Off” or “0”) when the input signal is greater than the reference signal.
The All / Nothing controllers are used in air conditioning thermostats. These activate the cold air (“On”) when the temperature is higher than the reference (the user preference) and deactivated (“Off”) cuando la temperatura ya es menor (o igual) the reference.
