XII. Operation
F. Changing Adjustable Parameters (continued)
Example Pump Parameter selections (continued):
Single Boiler with Supply Piped IWH, System and DHW Wired to Master
Parameter Selections:
System Pump = “Central Heat,
Optional Priority”
Boiler Pump = “any demand”
DHW Pump = “Primary Loop Piped IWH”
DHW Priority Enable is optional
Explanation:
When call for Domestic Hot Water is
received the DHW pump is turned on and
the boiler pump is turned on. 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.
