Functions
■ Weather-compensated control of the system/boiler water tempera-
ture in a multi boiler system with Vitodens 200-W with
Vitotronic 100, type HC1B (modulating) and the flow temperature
of the heating circuits with mixer
■ Control of the Vitotronic 100, type HC1B in boilers in accordance
with a freely selectable boiler sequence strategy
DHW heating in a multi boiler system
A Vitotronic 300-K
Control characteristics
■ PI characteristics with three-point output
■ Setting range for heating curves:
– Slope: 0.2 to 3.5
– Level: –13 to 40 K
– Max. limit: 1 to 127 °C
– Min. limit: 1 to 127 °C
– Differential temperature for heating circuits with mixer: 0 to 40 K
■ Setting range of the set DHW temperature:
Between 10 and 60 °C, adjustable to between 10 and 95 °C (avail-
able temperature limited by the max. boiler flow temperature).

■ Electronic maximum temperature limit
■ Demand-dependent heating circuit pump shutdown
■ Adjustment of a variable heating limit
■ Pump anti-seizing protection
■ Central fault message
■ Integral diagnostic system
■ Adaptive cylinder temperature control with priority control (heating
circuit pump off, mixer close)
■ Auxiliary function for DHW heating (short term heating to a higher
temperature)
■ Control of a cylinder loading system with a regulated 3-way mixing
valve
■ Screed drying for underfloor heating systems
To reduce the heat-up output, the reduced room temperature is
raised when outside temperatures are low. To shorten the heat-up
time after a setback phase the flow temperature is raised for a limi-
ted time.
According to the German Energy Saving Ordinance, the temperature
in each room must be individually controlled, e.g. by means of ther-
mostatic valves.
Connectivity
Vitoconnect 100, type OPTO1 (accessories):
WLAN interface for remote control of the heating system using the
Vitotrol Plus or the ViCare app. For further information, see the data
communication technical guide.
Time program
■ Individual day and seven-day program, holiday program
■ Automatic summer/wintertime changeover
■ Automatic function for DHW heating and DHW circulation pump
■ Time, day and standard switching times for central heating, DHW
heating and the DHW circulation pump are factory-set
■ Switching times are individually programmable; up to 4 time pha-
ses per day
Shortest switching interval: 10 min
Power reserve: 14 days
