Plant Configuration
Configure plant?
No
Yes
Plant configuration is related to shared
resources necessary for the operation of the
complete cascade/plant. To configure these
select ‘Yes’ and then follow the screens.
Hydraulic Separation:
If the boiler has Hydraulic Separation from
the intermediate or final circuits in the heating
system, or if the boilers have a combined flue
system then set this option to either ‘Header’
or ‘Plate heat exchanger’.

Header Thermistor:
If the system has a header sensor fitted,
combined flow, then select ‘Yes’, otherwise
the system will use the average flow
temperature of all running boilers.
Set Flue System:
If the boilers are connected into a common
or cascade flue system then you can choose
multiline flue system where the minimum
capacity of the boiler in a cascade can be
increased in order to ensure no backflow in
the flue system.

If the boiler cascade has a common pump
that circulates water through all the boilers
in the Cascade the select the output of
the Master boiler that controls this pump.
Otherwise select ‘None’.

Note: Once a programmable has been
selected the function will appear within the
parenthesis at the right of the designated
output name.
If the boiler cascade has a common pump
that circulates water through either the boiler
cascade or cascade header and supplies
the heating load then select the output of
the Master boiler that controls this pump.
Otherwise select ‘None’.

If the boiler cascade has a shunt pump to
control the temperature differential of the
cascade flow to return then select the output
of the Master boiler that controls this pump.
Otherwise select ‘None’.
