Depending on whether the bypass is energised by a
valve or by a second pump, a corresponding adjust-
ment can be made in the menu item Variant. De-
pending on the variant, different control logics are
applied:
Pump:
In this version, a bypass pump is placed in front of the
collector pump.
The bypass pump is fi rst activated when store loading
is possible. If the switch-on condition is fulfi lled, the
bypass pump is switched off and the collector circuit
pump is activated.
Valve:
A bypass valve is placed into the solar circuit.
The solar heat exchanger is fi rst bypassed when store
loading is possible. If the above-mentioned switch-on
condition is fulfi lled, the bypass relay switches the col-
lector circuit via the heat exchanger.
When the valve variant is selected, the option Invert-
ed is additionally available. When the Inverted option
is activated and the bypass circuit becomes activated,
the relay switches on. When solar loading starts, the
relay switches off again (see fi gure).

CS bypass
The CS bypass function is a different possibility to ac-
tivate the collector circuit. To enable the use of the
CS bypass function, a CS10 irradiation sensor has to
be connected.
When the CS bypass function is activated, the irradia-
tion value is the switch-on condition for the collector
circuit.
The relay remains switched on if the irradiation value

on value for the delay time, the relay is switched off.
When the Stmax off option is activated, collector
circuit activation is suppressed as long as all store
temperatures are above their respective maximum
temperatures.

Function block
In addition to the pre-defi ned optional functions, func-
tion blocks consisting of thermostat functions, timer
and differential functions are available. With the help
of these function blocks, further components, resp.
functions can be controlled.
To each function block, sensors and free relays can be
allocated. Sensors already in use can be allocated again
without impeding their control functions.
Within a function block the functions are intercon-
nected (AND gate). This means that the conditions
of all the activated functions have to be fulfi lled (e.
g. thermostat and timer) for switching the allocated
relay. As soon as one condition is not fulfi lled, the relay
is switched off.
Thermostat function
The relay allocated to the function block is switched
on, when the adjusted switch-on temperature (Th(x)
on) is reached. It is switched off when the adjusted
switch-off temperature (Th(x)off) is reached. The
switching conditions of all other activated functions of
the function block have to be fulfi lled as well.
Allocate the reference sensor in the Sensor channel.
Adjust the maximum temperature limitation with
Th(x)off> Th(x)on and the minimum temperature
limitation with Th(x)on> Th(x)off. The temperatures
cannot be set to an identical value.
∆T function
The relay allocated to the function block is switched
on as soon as the adjusted switch-on temperature dif-
ference (ΔTh(x)on) is reached. It is switched off as
soon as the adjusted switch-off temperature differ-
ence (ΔTh(x)off) is reached. The switching conditions
of all other activated functions of the function block
have to be fulfi lled as well.
The ΔT function is equipped with a speed control
function. A set temperature difference and a minimum
speed can be adjusted. The non-adjustable rise value
is set to 2 K.

Heating circuits
The controller has two internal, weather-compensat-
ed heating circuits and is able to control up to 5 ex-
ternal heating circuits by means of extension modules.
In the menu appearing when New heating circuit is
selected, it is possible to choose between the internal
heating circuits and, if available, registered modules.
If one or more extension modules are connected,
they have to be registered with the controller. Only
registered modules are available in the heating circuit
selection.
Extension modules can be registered in the In-/Out-
puts / Modules menu (see controller manual). If an
internal or external heating circuit has been selected,
a new menu opens. In this menu, all sensors and relays
required for the heating circuit can be allocated, and
all adjustments can be made.
The controller calculates the set fl ow temperature for
each heating circuit by means of the outdoor temper-
ature and the selected heating curve. If the measured
fl ow temperature deviates from the set fl ow tempera-
ture, the mixer is activated in order to adjust the fl ow
temperature correspondingly.
If the outdoor temperature falls below the point
where the calculated set fl ow temperature would ex-
ceed the maximum fl ow temperature, the maximum
fl ow temperature is treated as the set temperature
for as long as the condition remains.
If the outdoor temperature sensor is defective, an
error message is indicated. For the duration of this
condition, the maximum fl ow temperature -5 K is as-
sumed as set fl ow temperature.
With the timer, the day / night operation can be ad-
justed. During day phases, the set fl ow temperature is
increased by the adjusted day correction value, during
night phases it is decreased by the night correction
value (night setback).
Summer mode
The Mode channel adjustment determines how the
heating circuit is set to summer mode:
Summer off: The summer mode becomes active
when the outdoor temperature exceeds the adjusted
summer temperature TSummer.
Ext. switch: A switch is connected to a selected sen-
sor input. If the switch is operated, the heating circuit
is set to summer mode regardless of the outdoor
temperature.
Both: As long as the switch is not operated, summer
mode control works as described for Summer off.
Summer mode is activated regardless of the outdoor
temperature when the switch is operated.
Summer temperature
If Summer off or Both has been selected in the
Mode channel, the summer temperature TSummer
can be adjusted. If the outdoor temperature exceeds
the value adjusted in TSummer, the heating circuit
pump is switched off.
For the summer temperature, a daytime time frame
can be adjusted with the channels Daytime on and
Daytime off. Outside this time frame, the adjustable
temperature TNight replaces TSummer.
With the Room thermostat option, up to 5 room
thermostats can be integrated into the control logic.
To each room thermostat, a sensor input can be al-
located. The temperature at the allocated sensor is
monitored. If the measured temperature exceeds the
adjusted Room temperature value at all activated

room thermostats, the heating circuit pump is deac-
tivated and the mixer remains in its current position.
Common room thermostats with potential-free out-
puts can be used alternatively. In this case, Switch
must be adjusted in the Type channel. Before adjust-
ing the type, the corresponding input must also be set
to Switch in the Inputs / Outputs menu (see main
controller manual). Only inputs set to Switch will be
displayed in the Sen. RTH channel as possible inputs
for a switch type room thermostat.
If the Timer RTH option is activated, time frames
can be set for the room thermostats (for informa-
tion on how to adjust the timer see below). During
these time frames, the adjusted room temperature is
decreased by the Correction value.
To each room thermostat, an additional relay can be
allocated. That relay will operate when the tempera-
ture at the allocated sensor falls below the adjusted
room temperature. This way, the room in question can
be excluded from the heating circuit via a valve as long
as the desired room temperature is reached.
In the channel RTH, the room thermostat can be
temporarily deactivated or re-activated respectively.
All adjustments remain stored.
When the Timer option is activated, a timer is in-
dicated in which time frames for the function can be
adjusted.
First of all, an overview of the current adjustments is

Chimney sweeper function
The chimney sweeper function can be used for ena-
bling a quick access to measurement conditions with-
out menu operation for the chimney sweeper.
If the chimney sweeper function is activated, the chim-
ney sweeper mode can be accessed by pressing but-
ton 6 for 5 seconds.
In the chimney sweeper mode, the heating circuit mix-
er closes, the loading pump and the afterheating con-
tact are activated. While the chimney sweeper mode
is active, the directional pad is illuminated. Additionally,
Chimney sweeper and a countdown of 30 minutes
are indicated on the display.
When the countdown has elapsed, the chimney
sweeper mode is automatically deactivated. If, during
the countdown, button 6 is again pressed for more
than 10 seconds, the countdown starts again.
In order to abort the countdown and thus deactivate
the chimney sweeper mode, briefly press button 6.
Antifreeze option
The antifreeze option of the heating circuit can be
used to temporarily activate an inactive heating circuit
during sudden temperature drops in order to protect
it from frost damage.
When the antifreeze option is activated, the tem-
perature at the allocated sensor is monitored. If the
temperatur falls below the adjusted antifreeze tem-
perature, the heating circuit is activated for the ad-
justed runtime. Antifreeze operation has its own set
flow temperature which can be changed in the Flow
set channel.
