Page 171.11 Setting DHW flow temperatureThe DHW Setpoint Menu is displayed when the DHW+ button (1) or DHW- button (2) arepressed when the LCD is displaying the Home Screen.The actual DHW delivery temperature is dependent on site conditions, incoming watertemperature and flow rate.The setpoints are adjustable from 1 (lowest) to 9 (highest). Nominally the DHW flowtemperature (at the boiler) will be 40°C at the lowest setting and 70°C at the highest setting.A risk assessment should be conducted to determine the most appropriate anti-scald device tobe installed at all outlets, to limit the temperature of hot water outlets. These may include, butare not limited to bidets, taps and showers.Consult local building control regulations which apply to the installation for further reference.Example below shows the DHW setpoint at setting ‘5’.1.11.1 Multiple DHW SetpointsThe appliance has the ability to use two DHW setpoints, setpoint 1 displayed as ‘SEt 1’ (Normal)and setpoint 2, displayed as ‘SEt 2’ (Lower).Setpoint 2, (‘SEt 2’) can only be enabled with the built-in DHW programmer. See section 6.6.2for setting the DHW programmer. The advantage of the additional setpoint allows the DHWtemperature to be lowered at different times of the day. This can be a useful safety function,lowering temperatures when users such as children may be using outlets. The function canalso increase the efficiency of the appliance by lowering the DHW flow temperature duringcertain times of the day when a higher temperature is not required.The Mode button (3) is used to toggle between ‘SEt 1’ and ‘SEt 2’ when setting the DHWtemperature.During operation with the DHW programmer enabled, the appliance will revert to ‘SEt 2’ unlessa ‘SEt1’ time slot is active.
