Abstract
Systems, tools, and methods are presented that enable a circuit to introduce a random time delay before actuating a relay to start or stop a supply of electrical power to a heating element of a heating, ventilating, and air conditioning (HVAC) system. In one instance, the circuit includes a time-delay switch electrically connected to the relay. The time-delay switch has a random time delay before entering a closed state or open state. The relay is operable to start and stop a supply of electrical power to the heating element in response to the switch entering, respectively, the closed state and the open state. Other systems, tools and methods are presented.
