1.2 Boiler control units
1.2 Boiler control units and control panels
(for a comprehensive description, see data sheets boiler control units)
The following control units are available
for Vitogas 100 boilers:
For the operation of single boiler systems
Vitotronic 100 (type KC2)
H electronic boiler control unit for
constant boiler water temperature
or
weather-compensated operation, in
conjunction with an external control
unit
H for two-stage burners
H with DHW cylinder temperature control
(According to the Heating System Orders,
a weather-compensated or room
temperature-dependent control unit with
timer programming must be installed for
reduced operation.)
External commands:
H 1st burner stage ON
H 1st and 2nd burner stage ON
A volt-free contact must be provided for
each command.
The volt-free contacts are connected to
plug connector aBÖ and to the cable for
the 2nd burner stage at plug
connector lÖ.
Vitotronic 200 (type KW2)
H weather-compensated, digital boiler
control unit
H for single boiler systems
H for two-stage burners
H incl. digital timer with daily and weekly
programs
H with plain text guided programming
unit
H with separately adjustable periods
H with DHW cylinder temperature control
H with integrated diagnostic system.
Vitotronic 300 (type GW2)
H weather-compensated, digital boiler
control unit
H for single boiler systems
H for max. 2 heating circuits with mixer
H for two-stage burners
H with plain text guided programming
unit
H with separately adjustable periods and
heating curves
H with DHW cylinder temperature control
H incl. control unit for cylinder loading
systems with regulated 3-way valve
or
as alternative to regulating a constant
return temperature with regulated
3-way valve
H with integrated diagnostic system and
additional functions.
An extension kit is required for each
heating circuit with mixer. The LON
communication module is required for
LON BUS communication.
For the operation of multi-boiler systems
Multi-boiler systems are delivered
complete, comprising:
H 2 or 3 Vitogas 100
H 2 or 3 Vitotronic 100 (type GC1)
H 2 or 3 communication modules LON
H 1 Vitotronic 333 (type MW1)
Every boiler in a multi-boiler system is
equipped with Vitotronic 100 (type GC1).
Vitotronic 333 (type MW1) is part of the
standard delivery (see price list) and must
be installed separately.
The LON communication module must be
fitted into Vitotronic 100, see price list.
In multi-boiler systems with external
control unit, the load-dependent burner
and boiler control as well as the DHW
cylinder temperature control must be
implemented by the overriding (external)
control unit.
(On request)
External commands in conjunction with
Vitotronic 100 (type KC2) and external
weather-compensated control unit with
DHW cylinder temperature control:
H enable boiler
H 1st burner stage ON
H 1st and 2nd burner stage ON
A volt-free contact must be provided for
each command.
The volt-free contacts are connected to
plug connector aBÖ and to the cable for
the 2nd burner stage at plug
connector lÖ.
Vitotronic 100 (type GC1)
H Electronic boiler control unit
H for two-stage burners
H ability to communicate via LON BUS.
Vitotronic 333 (type MW1)

unit for multi-boiler systems with up to
3 boilers with Vitotronic 100.
(Type GC1)
H for max. 2 heating circuits with mixer
H with plain text guided programming
unit
H with DHW cylinder temperature control
H incl. control unit for cylinder loading
systems with regulated 3-way valve
H with sequential boiler strategy
H ability to communicate via LON BUS.
H with integrated diagnostic system and
additional functions.
Control panels
Vitocontrol control panels with
weather-compensated control unit
Vitotronic 333 (type MW1S) for 1 to 3
boilers and 2 heating circuits with mixers
and additional Vitotronic 050, types HK1S
or HK3S for 1 or up to 3 heating circuits
with mixers can be supplied for all
Vitogas 100.
