• The timings set on this screen prevent the boiler
from operating too long on one demand if
another demand is present. They also prevent
short cycling on a demand.
• LP1 and LP2 are times for local priorities.
• MIN NET ON TIME and MAX NET ON TIME
are the maximum and minimum times this
boiler will dedicate to a call from a network
demand.

• Use this screen to set how boilers are sequenced
and how usage is rotated between boilers on
the network.
• For a complete explanation of sequencing and
rotation, see page 58 and page 59.
• Sequencing means the way in which boiler
firing rate is controlled as boilers are turned on
and off by the master boiler.
– Three SEQUENCE TYPES are available:
SERIES sequencing allows each boiler to
reach full input before bringing on the next
boiler in sequence. PARALLEL sequencing
uses a limiter, called BASERATE HIGH, to
limit the firing rate before adding additional
boilers. SMART sequencing (factory default
setting) uses a low firing rate setting, called
BASERATE LOW, to keep boilers at a low
firing rate, bringing on additional boilers at
reduced rate until all boilers are on if neces-
sary. Boilers are then allowed to modulate to-
gether as high as necessary to meet demand.
• Rotation means how and how often the boiler
firing order is changed.
– LEAD BOILER ROTATE options are
based on how long a boiler has operated. Se-
lect either OFF, BY BOILER ID, TOTAL
HOURS or INCREMENTAL HOURS.
See detailed explanation of options on
page 58.
– Use the ROTATE FREQ setting to control
how often the rotation sequence is changed.
– FORCE LEAD ROTATE – If set to YES,
then when the frequency timer expires and
the new order is calculated, this forces the
new boiler order to take effect while a heat
demand is currently active.

• This screen appears ONLY on the master boiler,
not on shadow boilers.
• Set the time and date to ensure that control
logs accurately record time/date of occurrences.
• Time and date information is provided to the
shadow boilers by the master boiler.
