Two-position controller

The two-position controller (or three-position controller for heating/cooling) is used to activate

relays, contactors or thyristor switches for electric heating or cooling.
-

Two-position controller without feedback

In the simplest version without feedback, two-position controllers operate an on/off

switch. The controllers output is switched if the controlled variable violates the upper or

lower limits of the switching hysteresis (x1 and x2). The controlled variable x is subject to

permanent oscillation whose frequency and amplitude depend on the delay time of the

system and the switching hysteresis of the controller.
