ON Time: Elapsed time to make contacts after heater is energized (min. to max.)

OFF Time: Elapsed time to break contacts after heater is de-energized (min. to max.)

TABLE NOTES:

M1-M2 and M3-M4 are always first switches to turn ON and last to turn OFF. All other switches are random ON and random OFF

24A34-14 Switch contacts designated F1 - F2 instead of M1 - M2

24A34-28 is 2 pole double throw

These contacts switch simultaneously

NOTE: Underwriters Laboratories requires a fan interlock circuit to insure the blower remains operating whenever more than one sequencer is used. The fan interlock should be the M1 / M2 contacts of the second or third sequencer.

All M1 / M2 contacts are wired to the blower motor so that any sequencer that is energized will keep the blower ON.
