The requirements of DIN EN 12831 for heating load calculation
are met. To reduce the heat-up load, the night setback is reduced
in case of low outside temperatures. The flow temperature will be
raised for a limited time to reduce the heat-up time after a setback
period.
According to the Energy Savings Order [Germany], the tempera-
ture in each room must be individually controlled, e.g. through
thermostatic radiator valves.

Frost protection function
&The frost protection function will be started when the outside
temperature drops below approx. +1 °C.
With active frost protection, the heating circuit pump will be
switched ON and the boiler water is maintained at a lower tem-
perature of approx. 40 °C.
&The frost protection function will be switched OFF when the out-
side temperature rises above approx. +3 °C.
Summer mode
Heating program "w"
The burner starts only when the DHW cylinder needs to be heated
up again.
Adjusting the heating curves (slope and level)
The Vitotronic 200 controls the boiler water temperature (= flow
temperature of the heating circuit without mixer) and the flow tem-
perature of the heating circuit with mixer (in conjunction with the
extension kit for one heating circuit with mixer) subject to outside
temperature. The boiler water temperature is automatically
boosted by between 0 and 40 K higher than the currently required
set flow temperature (delivered condition 8 K).
The flow temperature required to reach a specific room tempera-
ture depends on the heating system and the thermal insulation of
the building to be heated.
Adjusting both heating curves matches the boiler water tempera-
ture and the flow temperature to these operating conditions.
Heating curves:
The upper boiler water temperature is limited by the temperature
limiter and the temperature set at the electronic maximum thermo-
stat.
The flow temperature cannot exceed the boiler water temperature.
Heating systems with low loss header
When using a hydraulic separation (low loss header), connect a
temperature sensor for use in the low loss header.
Boiler water temperature sensor
The boiler water temperature sensor is connected to the control
unit and built into the boiler.

Notes regarding room temperature hook-up (RS function) for remote control units
Never activate the RS function for underfloor heating circuits
(inertia).
The RS function must only affect the heating circuit with mixer.
Notes regarding the Vitotrol 200 and 300
If required, the Vitotrol 200 and 300 can also be used together in a
single heating system, respectively for one heating circuit each.
Vitotrol 200
Part no. 7450 017
KM BUS user
The Vitotrol 200 remote control regulates the heating program for
one heating circuit and the required set room temperature in stan-
dard mode, from any room in the house.
The Vitotrol 200 is equipped with illuminated heating program
keys and a party or economy key.
The fault display shows faults on the control unit.
WS function:
Installation at any point in the building.
RS function:
Installation in the main living room on an internal wall opposite
radiators. Never install inside shelf units, niches, immediately by a
door or heat source (e.g. direct sunlight, fireplace, TV set, etc.).
The integral room temperature sensor captures the actual room
temperature and effects any necessary correction of the flow tem-
perature as well as a rapid heat-up at the start of the heating
operation (if suitably encoded).
Connection:
&2-core lead, length max. 50 m (even if connecting several
remote control units)
&Never route this lead immediately next to 230/400 V cables
&LV plug as standard delivery
