The R8330D provides a recontrol replacement for most single or multiple element electric furnace sequencers. Each R8330D sequencer switches a fan and up to 3 heating elements. Two or 3 sequencers may be connected in series using the auxiliary switch(e). Two sequencers will control from 4 to 6 heating elements, 3 sequencers will control from 7 to 9 heating elements. The R8330D Electric Furnace Sequencer can be used for straight 240 volt isolated fan, combined 240 and 120 volt isolated fan, and 240 volt combination rated furnace system circuits. It may also be used in pilot duty limit systems when wired as shown in Figs. 15 and 16. Timing is 10 seconds minimum between stages. All stages of a single control sequence will come on within 2 minutes and go off within 4 minutes at nominal voltage and ambient temperature. The sequencer may be mounted in any position in the furnace. For installation
