DHW temperature selection.
When gas condensing boilers are combined with a DHW cylinder, setting 1-9 corresponds
to a cylinder temperature of 15-65 °C. The DHW temperature selector setting becomes
ineffective when the system is combined with a digital room thermostat or a weather-
compensated controller. The temperature will then be selected at the controller
(accessory).
Heating water temperature selection.
Settings 2-8 correspond, when factory-set, to a heating water temperature of 20-80 °C.
The heating water thermostat setting becomes ineffective when the system is combined
with a digital room thermostat or a weather-compensated controller.
