• The Lead Stage is the rst stage brought on when output is required
• Rotating the lead stage evens the wear on each stage and prolongs the
life of the units
• Only stages their Mode is set to Auto can be Lead Therefore, not all
stages may be available when manually selecting a new lead stage
• The current Lead Stage is shown in brackets on the display <A>

• Timed rotation starts the lead stage followed by the lag stage When
turning stages off, it turns off the lag stages before the lead stage
Example: If stages "<A>", "B", and "C" are on while "<A>" is the lead,
then when turning off the stages it will turn off stage "C" followed by "B"
and then nally "<A>"
• If 24 Hours (default setting) was selected, the rst rotation will take effect
after 12 hours The following rotations will take place every 24 hours
thereafter However, if Time rotation was set to other than 24 hours, the
rotation timer will start from the moment the setting is changed
• Unlike Time rotation, Last-On turns off the last stage turned on last
Example: If "<A>" is the lead, the starting sequence of the boilers will be
"A", "B", then "C" When the turning off the stages, it will turn off "A", "B",
followed by "C" Then, "<D>" will be the new lead stage
