Term Definition
Enable
Failsafe SP
Fail Safe Enable is available only in External Control and only if the "Burner On From"
is set to External Control. If this feature is active and the External Control voltage
drops below 0.25Vdc, the boiler automatically turns on the Boiler Pump (if set to "ON"),
the load pump, and operates the boiler to the Fail Safe Set Point temperature. This
temperature set point is adjustable.
Failsafe SP
Differential
The supply differential used by the subordinate boiler while in Failsafe SP mode. If the
supply temperature exceeds Failsafe SP + (Failsafe SP Differential) / 2, then the boiler
will enter Circulating until the supply temperature decreases to Failsafe SP – (Failsafe
SP Differential) / 2, at which point it will reignite and enter heating again.
Failsafe SP
Delay (min)
The delay in minutes of lost communication with the master, and the subordinate boiler
entering Failsafe SP mode.
Failsafe
Setpoint SP
When set to On, provides the ability to maintain a setpoint temperature in subordinate
boilers if communication with the master is lost.
Only available on subordinate boilers, it enables default setpoint operation. If a boiler
receives no communication from a master boiler for a period of time (how long?), it will
fire at the preset setpoint/differential until communication resumes.
Firing Order Firing Order determines which boiler is shut down first. If FirstOn/FirstOff is selected,
the first boiler fired up will be shutdown first. If FirstOn/LastOff is selected, then the
most recently fired boiler will be shutdown first.
Fixed Lead A boiler that is always the first to fire up. Appears as a field if Master, Primary Master,
or Secondary Master are set to "On". If Fixed Lead is set to "On", then the active
master will always attempt to fire first, before any other boilers. Otherwise, the boiler
with the lowest burner on time will attempt to fire first.
Fully
autonomous
mode
Designation of a master boiler that will receive all sensor and dry contact call-for-heat
signals, manage the secondary pump(s) and, via BoilerNet connection, coordinate
firing of all subordinate boilers. This fully autonomous approach uses IBC’s internal
heat regulation and boiler management software.
Group Add
Level (%)
Similar to Add Level (%) for master boilers, this is the relative output level at which the
Group Opt Out Lead will bring another boiler on to service the Group Opt Out load. Note
that this value must be at least 10 higher than Group Drop Level (%), which adjusts to
satisfy this if Group Add Level (%) is changed.
Group Drop
Level (%)
Similar to Drop Level (%) for master boilers, this is the relative output level at which the
Group Opt Out Lead will shut down a boiler that is currently servicing the Group Opt
Out load. Note that this value must be at least 10 lower than Group Add Level (%),
which adjusts to satisfy this if Group Drop Level (%) is changed.
Group Opt
Out Lead
This boiler is the Group Opt Out lead, and is the first to fire when a call for heat is
received on the Group Opt Out load. Makes the remaining Group Opt Out fields visible.
Group
Staging
Delay (min)
Similar to Staging Delay (min) for master boilers, this value determines the number of
minutes between boilers being fired up or shut down by the Group Opt Out Lead.
