DHW Boiler Setpoint is the xed appliance setpoint tem-
perature during a domestic hot water call when the Ther-
mostat option is chosen in Demand Type.
Adjust the DHW Boiler Setpoint value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 168°F
DHW Setpoint is the domestic hot water storage setpoint tem-
perature when the Sensor option is chosen in Demand Type.
Adjust the DHW Setpoint value using the LEFT or RIGHT
keys, then store the setting with the OK key.
Default: 140°F
The appliance setpoint is automatically set to the
DHW Setpoint + DHW Storage adder when the
Sensor option is chosen
NOTICE
DHW On Dierential sets how far the DHW storage tem-
perature must fall below the DHW Storage Setpoint to cre-
ate a domestic hot water call when the Sensor option is
chosen in Demand Type. The domestic hot water call will
end when the DHW storage temperature rises above the
DHW Storage Setpoint.
Adjust the DHW On Dierential value using the LEFT or
RIGHT keys, then store the setting with the OK key.
Default: 6°F
The DHW on differential setting greatly affects
the production of domestic hot water. A low set-
ting could result in a rapid response to a domestic
hot water call resulting in a potential scald haz-
ard. It is strongly recommended that the install-
er use a thermostatic mixing valve on the hot
water outlet of the Indirect Water Heater. Failure
to comply can result in substantial property dam-
age, serious injury, or death.
WARNING
DHW Maximum Capacity limits the maximum DHW capac-
ity. The appliance capacity can be dened by adjusting this
value, 100% means Maximum DHW output, 0% means mini-
mum DHW output. It is therefore possible to adjust the DHW
capacity to the installation needs.
Example: when set to 60%, the real appliance capacity is the
appliance minimum capacity plus 60% of the dierence be-
tween the maximum and minimum capacity.
Adjust the DHW Maximum Capacity value using the LEFT
or RIGHT keys, then store the setting with the OK key.
Default: 100%
