York S1-024-19082-034 Heat Sequencer Relay 24V

The York S1-024-19082-034 Heat Sequencer Relay is used to coordinate and regulate the heating processes of heating and cooling systems. It works with 24V to provide an orderly and systematic activation of several heating elements. The major function of this relay is to sequentially switch on heating elements as a result of system requirements. It operates through the control of the sequence in which the elements are switched on to control the heating load and prevent system overload. Such consecutive initiations ensure an orderly and effective heating process and enhanced general system effectiveness.
