Parameter Selections:
System Pump = “Central Heat,
Optional Priority”
Boiler Pump = “any demand”
DHW Pump = “Primary Loop Piped IWH”
DHW Priority Enable is optional
Explanation:
This piping arrangement permits the
system pump to run or not run when
there is a domestic hot water call for heat.
Domestic hot water priority is optional. It
is permissible for the domestic and system
pumps to run at the same time. The boiler
pump must run for every call for heat.
CAUTION:
It is the installers responsibility
to select boiler piping configurations that provide
the proper flow rates and performance for the boiler
and indirect water heater.

CAUTION:
It is the installers responsibility
to select boiler piping configurations that provide
the proper flow rates and performance for the
boiler.
Explanation:
This piping arrangement only
services central heat. When
there is any demand both
boiler and system pumps turn
on.
Parameter Selection:
System pump = “Central Heat,
Optional Priority”
Boiler pump = “any demand”
DHW pump = “never”
