Your Vitodens can be operated in the "Heating" or "DHW" operating modes.
Heating mode
If a Vitotrol 100 room temperature
controller is connected, it is used to
set the required room temperature.
Please refer to the separate operating
instructions.
If the setting on the room temperature
control unit is inadequate for achiev-
ing the required room temperature (e.
g. during an extremely cold winter),
the heating water temperature can
also be modified using the rotary
selector tr.
DHW heating - combi boiler
In the event of a demand for hot
water, the appliance will detect water
flow and initiate the ignition
sequence. The fan (and pump) will
start and the boiler will light.
If the hot water demand is near to the
maximum design flow rate the boiler
will run continuously at full output until
the tap is closed or the flow rate is
reduced, the heat input will be
reducedtomaintainasteadypre-set
temperature at the tap.
Hot water is available almost instanta-
neously from the boiler, but the final
outlet temperature and the delay in
reaching full temperature will depend
ontheflowrateandthedistancefrom
the boiler to the tap.
When the tap is closed the boiler will
return to heating mode, if there is a
demand for heating, otherwise the
boiler will shut down until the next
demand for heating or hot water.
