The boiler pump can be controlled in one
for two ways.
Capacity control means that the pump speed
follows the burner capacity proportionally between
minimum capacity/minimum pump speed and
maximum capacity/maximum pump speed.
Temp. Diff. Control means that the pump
speed is controlled to maintain a fixed boiler
flow to return temperature differential.

Menu – Boiler – Flue offset
The flue offset parameter allows adjustment
of the boiler specific cascade flue setting.
The flue offset is an increase in the minimum
burner capacity to ensure that the cascade flue
pressure or an unpowered flue damper can
be overcome safely and avoid any risk of the
burner going out at the minimum boiler capacity.
When a multiline flue system is selected during
configuration this parameter is enabled, it has a
predetermined minimum already applied which
is required for the optional flue kit that can be
supplied for the boiler.
