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.
Multiple Boilers with Boiler Piped IWH, System and DHW Wired to Master

Explanation:
Make sure indirect water heater and DHW pump are sized to maintain flow though boiler within limits shown in Table 12.
This piping arrangement does not allow both the Slave 1’s boiler and domestic hot water pump to run at the same time.
When call for Domestic Hot Water is received the DHW pump is turned on and the boiler pump is turned off. However, the
system pumps may run to satisfy a central heat demand that is being satisfied by a different slave. The central heat demand
is ignored by Slave 1 until the domestic hot water demand is ended. If domestic hot water priority is enabled and priority
protection time is exceeded the domestic hot water pump turns off to allow the boiler pump to run.
