One heating circuit without mixer and one heating circuit with
mixer and DHW heating
Applications
Heating system with different heat sources and methods of DHW heating
■ One heating circuit without mixer
■ One heating circuit with 3-way mixer
Main components
■ Oil condensing boiler, oil boiler or gas
boiler 18 to 100 kW
■ Heating circuit distribution
■ DHW cylinder
Function description
DHW heating
If the temperature falls below the set
DHW temperature at control unit 2, the
burner of boiler 1 starts and circulation
pump qE of DHW cylinder qP runs.
Within the periods selected at control
unit 2, DHW is heated with or without
priority control.
In case of absolute priority control, heating circuit pumps eQ/tR of the heating
circuits are switched off and mixer tT is
closed. With modulating priority control
of the heating circuit with mixer, heating
circuit pump tR remains on, and the
mixer tT closes far enough to enable the
set boiler water temperature for cylinder
heating to be reached. In this case, DHW
cylinder qP and heating circuit with
mixer tP are heated simultaneously.
5458 905 GB
Heating circuits eP/tP and DHW cylinder qP are regulated by boiler heating
circuit controller 1. The heating circuits
and DHW cylinder are each supplied by
a separate circulation pump eQ/tR and
qE.
The boiler heating circuit controller regulates the boiler water temperature in
weather-compensated mode (= flow
temperature of the heating circuit without
mixer) and the temperature level of the
heating circuit with mixer via an extension kit for one heating circuit with
mixer.

Preparing for installation
Heating mode
The boiler heating circuit controller regulates the boiler water temperature in
weather-compensated mode (= flow
temperature of the heating circuit without
mixer) and the temperature level of the
heating circuit with mixer via an extension kit for one heating circuit with
mixer.
DHW heating without a solar thermal
system
If the temperature falls below the set
DHW temperature at control unit 2, the
burner of boiler 1 starts and circulation
pump qE of DHW cylinder qP/qR runs.
Within the periods selected at control
unit 2, DHW is heated with or without
priority control.
In the case of absolute priority control,
heating circuit pumps eQ/rR/tR are
switched off and mixers rT/tT are
closed. With modulating priority control
of the heating circuits with mixer, heating
circuit pumps rR/tR remain on, and mixers rT/tT close far enough to enable the
boiler water temperature set for cylinder
heating to be reached. In this case, DHW
cylinder qP/qR and heating circuits with
mixer rP/tP are heated simultaneously.
5458 905 GB
DHW heating by the solar thermal
system
Solar circuit pump wE starts and DHW
cylinder qR is heated up, if the temperature differential between collector temperature sensor wQ and cylinder temperature sensor qT exceeds the start temperature differential.
Pump wE is stopped according to the following criteria:
■ The actual temperature drops below
the stop temperature differential
■ Exceeding the electronic temperature
limit (up to 90 °C) set in the solar control module (type SM1) wZ
■ The temperature selected at high limit
safety cut-out qZ (if installed) is
reached
Demands for the auxiliary function are
met by circulation pump wR.
Suppression of reheating of the DHW
cylinder by the boiler in conjunction
with the solar control module
Reheating suppression takes place in
two stages.
Reheating DHW cylinder qR by boiler
1 is suppressed as soon as DHW cylinder qR is heated by collectors wP. For
this, the set DHW temperature for
reheating is reduced by boiler 1. Suppression remains active for a certain time
after solar circuit pump wE has been
switched off (up to max. 24 h).
In the case of uninterrupted heating by
collectors wP (> 2 h), boiler 1 will only
reheat, if the set DHW temperature (coding address "67") selected at control unit
2 is not achieved.
In control unit 2, coding address "67"
defaults a third set DHW temperature
(setting range 10 to 95 °C). This value
must be below the first set DHW temperature.
DHW cylinder qR will only be heated by
boiler 1 when this set value is no longer
achieved by the solar thermal system.

Heating circuit tP and DHW cylinder
qP are regulated by boiler heating circuit

Directives
Danger
Incorrectly executed electrical
installations can lead to injury
from electrical current and result
in equipment damage.
Make the power supply connection and implement all protective
measures (e.g. RCD circuit) in
accordance with the following
regulations:
■ IEC 60364-4-41
■ VDE regulations
■ Connection requirements
specified by your local power
supply utility
■ Protect the power cable with
max. 16 A
For combustion equipment to DIN VDE
0116, the mains isolator installed on site
must comply with the requirements of
DIN VDE 0116 "section 6" [or local regulations].
Fit the mains isolator outside the installation room; it must be able to separate
all non-earthed conductors simultaneously with a gap of 3 mm at least.
We additionally recommend installing an
AC/DC-sensitive RCD (RCD class B
) for DC (fault) currents that can occur
with energy-efficient equipment.
If no main isolator is installed, all nonearthed cables must be isolated from the
mains by the upstream circuit breaker
with at least 3 mm contact separation.
Replacing the power cable
Three-core cable selected from the following options:
■ H05VV-F3G 0.75 mm2
■ H05RN-F3G 0.75 mm2
5458 905 GB
Danger
The absence of component
earthing in the system can lead to
serious injury from electrical current if an electrical fault occurs.
Connect the appliance and pipework to the equipotential bonding
of the house in question.

Adjusting heating curves
The room temperature, again, depends
on the boiler water or the flow temperature.
Settings in the delivered condition:
■ Slope = 1.4
■ Level = 0
5458 905 GB
The heating curves illustrate the relationship between the outside temperature
and the boiler water or flow temperature.
To put it simply: The lower the outside
temperature, the higher the boiler water
or flow temperature.

Brief description
■ The boiler water temperature is regulated by starting or stopping the burner
or through modulation. In the delivered
condition, the switching differential is
±2 K, relative to the current set value.
■ The set boiler water temperature is
determined from the following parameters:
– Set flow temperature of the heating
circuits and those connected via the
LON
– Set DHW temperature
– External demand
■ When the DHW cylinder is heated up,
a set boiler water temperature is
defaulted that lies 20 K above the set
DHW temperature (adjustable via coding address "60").
■ Coding addresses that influence the
regulation of the boiler water temperature:
"02", "04", "06", "13" in the "Boiler"
group.
For a description, see codes overview.

Heating circuit control
Brief description
■ The control unit has control circuits for
a heating circuit without mixer HC1
and two heating circuits with mixer
HC2 and HC3.
■ The set flow temperature of every
heating circuit is determined from the
following parameters:
– Outside temperature
– Set room temperature
– Operation
– Heating curve slope and level
■ The flow temperature of heating circuits without mixer is equal to the
boiler water temperature.
■ The flow temperature of the heating
circuits with mixer is regulated by the
stepped opening or closing of the mixers.
The mixer motor control changes the
actuating and pause times subject to
the control differential (control deviation).
■ Coding addresses that influence the
heating circuit control:
"9F" in the "General" group and "A0"
to "Fb" in the "Heating circuit..."
group.
For a description, see codes overview.

Checking the rotational direction of the mixer motor
After being switched on, the extension kit
implements a self-test. During this, the
mixer is opened and closed again.
Note the rotational direction of the mixer
motor during its self-test.
Then set the mixer manually to "Open"
again.
Note
The flow temperature must now rise. If
the temperature drops, either the motor
is turning in the wrong direction or the
