• In this example, automatic rotation
(*)
is performed every two days at a specified time (in
accordance with the rotation
(*)
flag setting for the boiler No.

• At the rotation
(*)
time, a higher priority order is given to the boilers in which the cumulative
combustion time is shorter.
• For the boiler of which rotation
(*)
flag is set to 9 (boiler No.
(*)
3), the priority
(*)
is fixed.
NOTE
If the automatic rotation
(*)
function is utilized at intervals from 1 to 12 hours, it is necessary
to check the version of each MI Terminal MT1-200 and the Pressure Controller MP1-200.
