DOMESTIC HOT WATER (DHW)
APPLICATIONS
The Prestige Boiler provides a domestic hot water
(DHW) priority feature, which will block a heating call
when a domestic hot water call is present. The length of
time that a domestic call has priority over a heating call
can be set with Parameter 43. A domestic call can be
sent from either an Aquastat or an NTC sensor in the
Indirect Water Heater. The type of domestic call signal
can be changed with Parameter 46. During a domestic
call, the DHW circulator will be enabled and the boiler
setpoint will be set to the DHW setpoint. The boiler set-
point for a domestic call is calculated by adding
Parameters 1 & 21. The central heating (CH) circulator
will be disabled from providing water to the space heat-
ing system during a domestic call.
DHW APPLICATION SELECTION
(PARAMETER 2)
The boiler response to a domestic hot water call can be
changed with Parameter 2. Parameter 2 provides 4 dif-
ferent modes of domestic hot water operation.
DHW Application Selection Options
(Parameter 2)
DHW Call Disabled
(Parameter 2 = 00)
The boiler will not respond to a domestic call from an
Indirect Water Heater. Both the burner and DHW circu-
lator will remain off during a domestic call. The boiler will
continue to respond to a call for heat from the heating
system.
DHW Call Enabled – Factory Setting
(Parameter 2 = 01)
The boiler will respond to a domestic call from an Indirect
Water Heater. Both the burner and DHW circulator will
operate during a domestic call. A domestic call has pri-
ority over a heating system call for heat. The boiler set-
point will be set to the DHW setpoint and the DHW cir-
culator will run. The CH circulator will be off.
Burner Disabled, DHW Pump Continuous
(Parameter 2 = 02)
The burner will not respond to a domestic call from an
Indirect Water Heater. The DHW circulator will run con-
tinuously, even during a heating call. The boiler will con-
tinue to respond to a call for heat from the heating system.
Burner Enabled, DHW Pump Continuous
(Parameter 2 = 03)
The boiler will respond to a domestic call from an Indirect
Water Heater. The burner will operate during a domes-
tic call. The DHW circulator will run continuously, even
during a heating call. A domestic call has priority over a
heating system call for heat. The boiler setpoint will be
set to the DHW setpoint. The CH circulator will be off.
