2 Safety notes
2.1 Notes on product liability
• The device may only be used in building services plant and applications as
described in this document
• Comply with all requirements specified in chapters "Handling" and "Technical
data" when using the device.
• Local regulations (for installation, etc.) must be complied with
• Do not open the device. If not observed, warranty becomes void.

3 Mounting and installation
3.1 Regulations
3.1.1 Electrical installation
• Prior to installing the units, power must be turned off
• The connections for mains and low-voltage are separated
• The wiring must be made in compliance with the requirements of safety class II.
This means that sensor and mains cables must not be run in the same duct
3.2 Planning
• Air circulation around the controller must be ensured, allowing the unit to emit
the heat produced by it.
• The controller is designed to conform to the directives for safety class II devices
mounted in compliance with these regulations.
• Power to the controller may only be supplied when fully mounted / electric
installation is complete. If this is not observed, there is risk of electric shock near
the terminals
• The controller must not be exposed to dripping water
• Permissible ambient temperature when mounted and when ready to
operate: 0…50 °C
• Power cables must be clearly separated from low-voltage cables (sensors)
observing a distance of at least 100 mm

Operating state
Diagnosis
To commission the units, the following working steps must be carried out:
•
Make certain that mounting and electrical installation are in compliance with the
relevant requirements.
• Make all plant-specific settings. Special attention must be paid to menu
"Configuration". For that purpose, the relevant operating level is selected as
follows:
• Press the OK button to switch to programming.
• Press the Info button for at least 3 seconds and select operating level
"Commissioning" with the setting knob. Then, press the OK button.
• Make the function check as described below
To facilitate commissioning and fault tracing, the controller can be used to make
input and output tests. With these tests, the controller’s inputs and outputs can be
checked. To make the tests, switch to menu "Input / output test" and go through all
available setting lines.
The current operating state can be checked on menu "State".
For detailed diagnostics of the plant, check menus "Diagnostics heat generation"
and "Diagnostics consumers".

5.4 Programming
5.4.1 Setting principle
Settings that cannot be made directly with the help of operating elements are made
through programming. For this purpose, the individual settings are structured in the
form of menus and operating lines, thus creating practical groups of settings.
The following example shows how to set the time of day and the date.
5.4.2 Example: "Setting the time of day"
• Press
OK to go to programming.
• Press the ESC button to go one step back at a time, readjusted values are not
adopted
• If no setting is made for 8 minutes, the display returns automatically to the basic
display
• Operating lines may be hidden, depending on configuration and user level

The charging setpoint of the storage tank with first-priority charging and the
collector temperature are used for speed control. A PI controller calculates the
speed required to ensure that the collector temperature is 2 K below the switch-on
temperature.
If the collecto
r temperature rises due to increased solar radiation, the speed is
increased. If the collector temperature drops below this setpoint, the speed is
reduced.
Limit parameters can be set to define a maximum and minimum pump speed
(operating lines 3870 and 3871).
The PI controller can be influenced by parameters Xp and Tn. The controller has a

The 24-hour and total solar energy yield (8526 and 8527) is calculated, based on
these data.
Since the mixing ratio of the collector medium has an impact on heat transmission,
the type of antifreeze used and its concentration must be entered in order to be
able to determine the energy yield.
Two additional sensors can be configured (Solar flow sensor B63, Solar return
sensor B64). Collector sensor B6 is used if B63 is unavailable; the applicable
storage tank sensor B31/B41 is used if B64 is unavailable.
Pump capacity for the corresponding pump must be entered if there is no pulse
measurement.
The yield measurement then uses this volumetric flow (l/h) for the calculation.
Each pulse received can be interpreted as a value (kWh or liters).
The pulse value is defined using settings 3887-3889 (unit, counter and
denominator).

Reduce temperature Operation action of return
If the return temperature from the consumers is higher than the temperature at the
selected sensor (OL 4795), the return can be used to preheat the lower part of the
storage tank. As a result, the return temperature continues to drop which, in the
case of a condensing boiler, leads to higher efficiency.
Temperature increase
If the return temperature from the consumers is lower than the temperature at the
selected sensor (OL 4795), the return can be preheated by diverting it via the lower
part of the storage tank. It is thus possible to preheat the return, for example.

6.10 Configuration
6.10.1 Procedure
First, make use of the presetting choices and enter the plant diagram that comes
closest to the plant in question. Then, modify manually the individual partial
diagrams to match them to the actual requirements.
After that, select the extra functions and make the fine-tuning via the operating
lines of the individual parameters.
6.10.2 Preselection of plant diagram
Line no. Operating line
5700 Presetting
--- ¦ 1-5
Five presettings are available for various types of storage tank management. Presele
The se
con
nsors contained in the desired plant diagram (see pg. 52 et seq.) must be
nected prior to setting.
Presetting number Description Required sensors / pumps
1 DHW or buffer storage tank charge B6 / Q5 / B31 or B41
2 DHW or buffer storage tank charge with external heat

6.10.3 Manual selection / Adaption of partial diagrams
A plant diagram consists of several partial diagrams.
It is possible to manually compose the required plant diagram from the respective
partial diagrams.
But it is also possible to modify and adjust partial diagrams of a plant diagram
generated via "Presetting" (5700).
The partial diagrams in the controller are listed in Section "Applications" (see page
52 et. seq.). Also listed in the catalogue are the re
quired operating lines which must
be set to produce the respective partial diagrams, plus the sensors required for the
relevant partial diagram.

Solar controlling element buffer K8
If several heat exchangers are used, the buffer storage tank must be set at the
respective relay output and, in addition, the type of solar controlling element must
be defined on OL 5840).
Solar pump external exchanger K9
For the external heat exchanger, solar pump "Ext heat exchanger K9" must be set
at the multifunctional relay output (ZX1).
Alarm output K10
The alarm relay signals faults, should they occur.
Switching on takes place with a delay of 2 minutes.
When the fault is corrected, that is, when the error message is no longer present,
the contact opens with no delay.
If the fault cannot immedi
ately be corrected, it is still possible to reset the alarm
relay. This is made on operating page "Faults".
Storage tank transfer pump Q11
If the temperature level of the buffer storage tank is high enough, the DHW storage
tank can be charged by the buffer. This transfer can be made by means of transfer
pump Q11.
Buffer return valve Y15
The valve must be configured for return temperature increase / decrease or buffer
storage tank partial charging.
Solid fuel boiler pump Q10
For the connection of a solid fuel boiler, a circulating pump for the boiler circuit is
required.
DHW electric immersion heater K6
Using the connected electric immersion heater, the DHW can be heated up
according to operating page "DHW storage tank", operating line "Electric
immersion heater".
The ele

Output K27 is enabled as soon as there is a heat request.
Overtemperature protection K11
Output K11 is enabled when the tempature reaches the set overheat protection
temperature (6209) on the defined reference sensor (OL6208).
It remains enabled until the temperature drops below the overheat protection
temperature by the set switching differential (6210).

Predefined plant diagrams (basic diagrams) can be selected via OL 5700.
The selection of a basic diagram automatically defines the terminals required for
