Possible applications
Heating systems with distributor
installed close to the boiler. The
boiler water volume flow must be
able to be reduced.
If the factory−set temperatures are
not reached at the ThermControl
temperature sensor, ThermControl
will activate the heating circuit
control unit(s) or the heating circuit
pump(s). In the start−up phase (e.g.
during commissioning or after a
night or weekend shutdown), the
boiler water volume flow must be
reduced by at least 50 %.
The boiler is best protected when
regulating the heating circuits via
Vitotronic050 connected to the
boiler control unit. No additional
on−site protective measures are
required.
Therm−Control
Wiring in heating systems with
heating circuit control units which
are not connected to the boiler
control unit via the LON BUS.
Required coding: "4C:2".

Possible applications
Heating systems with distributor
installed close to the boiler. The
boiler water volume flow will be
reduced by the motorised butterfly
valve.
In multi−boiler system without
Vitotronic 333, cascade and cylinder
control must be provided by a higher

If the factory−set temperatures are
not reached at the ThermControl
temperature sensor, ThermControl
will regulate the motorised butterfly
valves. Where ThermControl cannot
affect the motorised butterfly valves
it must, instead, regulate the mixers
of the downstream heating circuits.
In the start−up phase (e.g. during
commissioning or after a night or
weekend shutdown), the boiler water
volume flow must be reduced by at
least 50%.

regulates the boiler water
temperature subject to the
respective boiler.
Control sequence
Boiler heats up
The burner shutdown point is
determined by the shutdown
differential (coding address "13").
5862730GB
Boiler goes cold
(set value 2 K)
The burner start signal is set at the
set boiler water temperature less 2 K,
and the burner starts its own
monitoring program.
The burner start may be delayed by a
few minutes subject to the number
of the auxiliary circuits and the
combustion type.

Function description
Cylinder temperature control (only for single boiler systems)
Brief description
The cylinder thermostat operates
with a constant temperature. It is the
result of starting and stopping the
cylinder primary pump.
The switching differential is ±2.5 K.
Coding addresses which influence
the cylinder thermostat
4E, 54, 55, 56, 58 to 5A, 60 to 63,
67 to 69.
For a description, see page 147.
During cylinder heating, a constant
upper boiler water temperature will
be set (20 K higher than the set
cylinder temperature, adjustable via
coding address "60").
Functions
Frost protection
The DHW cylinder will be heated to
20 ºC if the DHW temperature drops
below 5 ºC.
System with cylinder storage system
The above functions also apply in
conjunction with cylinder storage
systems.
Auxiliary function for DHW heating
This function is enabled by providing
a second set DHW temperature via
coding address "58" and by
determining a time via coding
address "63".
Heating up with the auxiliary
function takes place with the first
heating up of the cylinder each day.
Set the following codes:
"4C:1", "4E:1", "55:3"
(see page 146).
5862730GB
Set DHW temperature
The set DHW temperature can be
adjusted between 10 and 60 ºC. The
set range can be extended to 95 ºC
via coding address "56".
System with Vitosolic
A third set DHW temperature can be
defaulted via coding address "67".
Reheating will be suppressed above
the selected temperature. The DHW
cylinder will only be heated by the
solar heating system.

Function description
Cylinder temperature control (only for single boiler systems) (cont.)
Control sequence
H The cylinder primary pump runs on
after cylinder heating, until
the difference between the boiler
water and the DHW temperature
is less than 7 K or
the weather−compensated set
flow temperature has been
reached or
the actual temperature is 5 K
higher than the set DHW
temperature or
the maximum run−on time
(adjustable via coding
address"62") has been reached.
H Without the cylinder primary pump
running on
(code "62:0")
Code "55:0"
Cylinder heating
DHW cylinder goes cold
(set value 2.5 K, adjustable via
coding address "59")
The DHW cylinder is hot
(set value +2.5 K)
The set boiler water temperature is
returned to the programmed set
value.
Code "55:1":
Adaptive cylinder heating
With adaptive cylinder heating, the
speed of the temperature rise during
DHW heating is taken into account.
Also taken into account is the
question of whether the boiler will
be required to supply heat after the
cylinder has been heated up or
whether residual boiler heat should
be transferred to the DHW cylinder.
Accordingly, the control unit
determines the burner and pump
shutdown points to prevent the set
DHW temperature being
substantially exceeded after the
cylinder has been heated up.
5862730GB
The set boiler water temperature is
adjusted 20 K higher than the set
DHW temperature (adjustable via
coding address "60").
H Starting the cylinder primary pump
subject to boiler water temperature
(code "61:0"):
The pump starts when the boiler
water temperature is 7 K higher
than the DHW temperature.
H Immediate start of the cylinder
primary pump (code "61:1").

Cylinder temperature control with
2 cylinder temperature sensors
Cylinder temperature sensor 1
enables the cylinder primary pump,
and is evaluated for stop conditions
during the pump run−on time.
Cylinder temperature sensor 2
(inside the cold water inlet) is
designed to start cylinder heating
prematurely when large volumes of
DHW are drawn off as well as to stop
cylinder heating prematurely, if no
DHW is drawn.
Select starting and stopping points

Immediately, if the three−way
mixing valve is fully open
or
after expiry of a run−on time
adjustable via code "62".
5862730GB
DHW cylinder goes cold

coding address "59"),
H The set boiler water temperature is
adjusted 20K higher than the set
DHW temperature (adjustable via

H The cylinder primary pump is
switched ON.
H The three−way mixing valve opens
and then regulates to the defaulted
set value.
H The cylinder primary pump cycles
(short term ON and OFF) until the
set flow temperature has been
reached (set DHW temperature
+ 5K), then it runs constantly.
If, during cylinder heating, the
actual value stays below the
required set temperature, then the
cylinder primary pump will
temporarily cycle again.
