2.1 Mounting
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note:
Strong electromagnetic fields can impair the function of the controller.
ÎMake sure the controller as well as the system are not exposed to
strong electromagnetic fields.
The device must only be located in dry interior rooms.
The controller must additionally be supplied from a double pole switch with contact
gap of at least 3 mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
ÎUnscrew the crosshead screw from the cover and remove it along with the
cover from the housing.
ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding.
ÎHang the housing from the upper fastening point and mark the lower fastening
point (centres 130 mm).
ÎInsert lower wall plug.
ÎFasten the housing to the wall with the lower fastening screw and tighten.
ÎCarry out the electrical wiring in accordance with the terminal allocation (see
page 5).
ÎPut the cover on the housing.
ÎAttach with the fastening screw.
2.2 Electrical connection
ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
ÎTake care to discharge properly before touching the
inside of the device! To do so, touch a grounded sur-
face such as a radiator or tap!
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note:
Connecting the device to the power supply must always be the last step
of the installation!
Note:
The pump speed must be set to 100% when auxiliary relays or valves are
connected.
The controller is supplied with power via a mains cable. The power supply of the
device must be 100… 240 V~ (50 … 60 Hz).
The controller is equipped with 4 relays in total to which loads such as pumps,
valves, etc. can be connected:
• Relays 1 … 3 are semiconductor relays, designed for pump speed control.
Conductor R1 … R3
Neutral conductor N
Protective conductor 
• Relay 4 is a potential-free low voltage relay
Depending on the product version, mains cables and sensor cables are already con-
nected to the device. If that is not the case, please proceed as follows:
Connect the temperature sensors (S1 to S5) to the corresponding terminals
with either polarity:
S1 = Sensor 1 (collector sensor )
S2 = Sensor 2 (store sensor base)
S3 = Sensor 3 (e. g. store sensor top)
S4 = Sensor 4 (e. g. washing machine)
S5 = Sensor 5 (e. g. sensor collector 2)

fer to a computer, the values can be opened and visualised, e. g. in a spreadsheet.
• Prepare adjustments and parameterisations on a computer and transfer them via
the MicroSD card.
• Store adjustments and parameterisations on the MicroSD card and, if necessary,
retrieve them from there.
• Download firmware
updates from the Internet and install them on the controller
via MicroSD card.
MicroSD card slot

System 1: Standard solar system with 1 store
The controller calculates the temperature difference between collector sensor
S1 and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference, the pump (R1) will be switched on and the store
will be loaded until the switch-off temperature difference or the maximum store
temperature is reached.

The controller compares the temperatures at the collector sensors S1 and S5 to
the store temperature at sensor S2. If one of the measured temperature difference
is higher than the adusted switch-on temperature difference, the corresponding
pump (R1 and/or R2) will be switched on, thus loading the store until either the
switch-off temperature difference or the store maximum temperature is reached.

System 11: Solar system with 1 store, return preheating and thermostatic afterheating
The controller calculates the temperature difference between collector sensor
S1 and store sensor S2. If the difference is larger than or identical to the adjusted
switch-on temperature difference, the pump (R1) will be switched on and the
store will be loaded until the switch-off temperature difference or the maximum
store temperature is reached.
Afterheating (R4) can be carried out with a thermostat function (S3). If the value
at S3 reaches the switch-on temperature for the afterheating, the relay is switched
on. If the value exceeds the switch-off temperature for the afterheating, the relay
is switched off again.
With another temperature differential function (S3 heat source/S4 heat sink) re-
turn preheating (heating circuit backup) is possible via another pump (R2). If the
value at S5 falls below the adjusted room temperature and the adjusted time frame
is active, the pump (R2) will be switched on. If the value exceeds the adjusted
room temperature or the adjusted time frame is inactive, the pump (R2) will be
switched off.

3 Operation and function
3.1 Buttons and adjustment dial
The controller is operated via 2 buttons and 1 adjustment dial (Lightwheel®) below
the display:
Left button (') - escape button for changing into the previous menu
Right button () - confirming / selecting
Lightwheel®- scrolling upwards/ scrolling downwards, increasing adjustment
values / reducing adjustment values
3.2 Microbuttons for manual mode and holiday mode
The controller is equipped with 2 microbuttons for quick access to the manual
mode and the holiday function.The microbuttons are located underneath the slida-
ble housing cover, the slider.
Mircobutton : If the microbutton is briefly pressed, relay 1 will be set to the
manual mode for 1 minute (see page 43).
Microbutton : The microbutton is used for activating the holiday mode (see
page 42). If the microbutton is pressed and held down for ap-
prox. 3 s, the adjustment channel DAYS appears, allowing to enter
the number of days for an absence. If the parameter is set to a
value higher than 0, the function becomes active using the adjust-
ments that have previously been made in the H-DAY menu. The
days will be counted backwards from 00:00 o'clock. If the value is
set to 0, the function is deactivated.
Electrical connection of a high-efficiency pump (HE pump)
Speed control of a HE pump is possible via a PWM signal/ 0-10V control.The pump
has to be connected to the relay (power supply) as well as to one of the PWM A/B
outputs of the controller. In the REL adjustment channel one of the PWM control
types as well as a relay have to be selected (see page 47).

The menu level consists of the balance values menu and several menu items each
of which consists of sub-menus and adjustment channels. In order to activate or
deactivate a function, it must be selected in the menu level.The display changes to
the adjustment menu in which all adjustments required can be carried out.
Note:
Some of the menu items depend on the selected system and the adjusted
options.Therefore, they are only displayed if they are available.
Note:
The abstract from the menu structure is for information on the structure
of the controller menu and is therefore not complete.
3.5 Selecting menu points and adjusting values
During normal operation of the controller, the display shows the status level with
the adjustment channels. If no button is pressed for 1 min, the display illumination
goes out. If no button is pressed for further 3 min, the display indicates the status
level.
Press any key to reactivate the display illumination.
