This sequencer is a direct replacement unit for sequencing both fan and heat. It can be used in a broad range of gas and electric heating equipment and many other applications where time delay is required. This sequencer has a solid-state 24 volt heater, used to energize the control, and a variety of normally open contact sets. These contacts close and open within specified timings and are used to control the furnace fan and heating elements on demand from a room thermostat.
This sequencer meets a wide variety of timing requirements and assures long life at high electrical loads as well as minimum radio and TV interference. Each sequencer is stamped with timing specifications. For example, H1-20 C40-110 means the ON time for heating is 1 to 20 seconds and the OFF time for cooling is B40 to 110 seconds. First contacts turn ON first and turn OFF last; others are random On and random OFF.
