PReSS TO SeleCT: /<System Settings>/.../<Stage Settings>/<Lead Settings>/Rotate Mode
• Automatically rotating the lead stage promotes even wear on all the
stages and prolongs their lives .
Manual
• In Manual, No rotation of lead stage . Select the lead stage manually from
the previous menu .
Time
• 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 finally "<A>" .
• If 24 Hours (default setting) was selected, the first 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 .
last on
• 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 .
