Shunt Pump:
Shunt Pump. If the boiler has a Plant
Shunt Pump connected between the
Flow and Return headers then select the
output that is used to control it from the
list. Otherwise select ‘None’.
Once an output has been configured the
selected function is shown in brackets
behind the output name.
System Fault Indication:
If the Master boiler has Slave boilers or
Extension Modules connected and the
requirement to signal errors for the plant
then select the output that is used to
control it from the list. Otherwise select
‘None’.
0-10V Input:
If the Plant is to be controlled by a single
0-10V signal, this can be configured.
Otherwise set to ‘None’.
The options are Capacity or Temperature
control, with additional parameters for
Temperature control:
0-10V input Temp. Setp. 0V:
0-10V input Temp. Setp. 10V:
Configure 0-10V Parameters:
Voltage life zero. This setting determines
the minimum keep alive voltage where the
system expects a voltage to be present on
an operational interface, anything below
this indicates a wiring fault:
Voltage demand. This setting determines
the switching point at which demand is
expected by the system, anything below
this is at keep alive voltage:
