DHW DHW Boiler Setpoint is the fixed appliance setpoint temperature during a domestic hot water call when the Thermostat option is chosen
Boiler Setpoint
in Demand Type.
75°C
Press the LEFT or RIGHT buttons to adjust the DHW Boiler Setpoint then press the OK button to store the setting.
87°C
Default: 75°C
DHW Setpoint is the domestic hot water storage setpoint temperature when the Sensor option is chosen in Demand Type.
DHW Setpoint
Press the LEFT or RIGHT buttons to adjust the DHW Setpoint then press the OK button to store the setting.
60°C
Default: 60°C
75°C
The appliance setpoint is automatically set to the DHW Setpoint + DHW Storage adder when the Sensor option is chosen
in DHW demand
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
3°C
rises above the DHW Storage Setpoint.
Press the LEFT or RIGHT buttons to adjust the DHW On Differential then press the OK button to store the setting.
10°C
Default: 3°C
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 appliance set-
point will be DHW Storage Setpoint + DHW Storage Adder for a domestic hot water call.
15°C
Press the LEFT or RIGHT buttons to adjust the DHW Storage Adder then press the OK button to store the setting.
30°C
Default: 15°C
