Control unit / Function / Operation
DHW temperature selector
When gas fired condensing boilers are combined with a DHW cylinder, setting 1 - 9
corresponds to a cylinder temperature of 15 - 65 °C. The setting on the DHW thermo-
stat becomes ineffective when the system is used in conjunction with a digital room
thermostat or a weather-compensated controller. The temperature will then be selected
at the controller (accessories). With combi boilers, setting 1 - 9 corresponds to a DHW
temperature of 40 - 60 °C.
Heating water temperature selector
The factory setting range 2 - 8 corresponds to a heating water temperature of 20 - 75 °C.
The setting on the heating water thermostat becomes ineffective when the system is used
in conjunction with a digital room thermostat or a weather-compensated controller.
ON/OFF switch
The gas fired boiler is OFF in position 0.
Reset
A fault is reset by pressing the reset button which will also restart the system. Pressing
the reset button reactivates the system, if there was no fault.
