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 M

sequencer.
All M

contacts are wired to the blower mo-
tor so that any sequencer that is energized will
keep the blower ON.
