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
