DHW Boiler Setpoint
is the fixed appliance setpoint temperature during a domestic hot water call when the Thermostat option
is chosen in Demand Type.
This function is not applicable to Evo models. The screen is displayed and available, but any change made here will have no effect.
DHW Setpoint
is the domestic hot water storage setpoint temperature when the Sensor option is chosen in Demand Type.
Touch the
LEFT
or
RIGHT
soft keys to adjust the DHW Setpoint then touch the
OK
key to store the setting.
Default: 60°C
DHW On Differential
sets how far the DHW storage temperature must fall below the DHW Storage Setpoint to create 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.

• The appliance setpoint is automatically set to the DHW Se DHW Storage adder when the Sensor option
is chosen in DHW demand.
• Increase this value up to at least 70°C to enable the DHW Boost function
The DHW on differential setting greatly affects the production of domestic hot water. A low setting could result in a rapid
response to a domestic hot water call resulting in a potential scald hazard. It is strongly recommended that the installer
use a thermostatic mixing valve on the hot water outlet of the Indirect Water Heater. Failure to comply could result in
severe personal injury, death, or substantial property damage.
DHW Storage Adder
is used to compute the appliance setpoint when the Sensor option is chosen in Demand Type. The appli-
ance setpoint will be DHW Se DHW Storage Adder for a domestic hot water call.
Touch the
LEFT
or
RIGHT
soft keys to adjust the DHW Storage Adder then touch the
OK
key to store the setting.
