1. What can your new controller do?
Your solar controller is a microprocessor-based controller, for control of solar energy systems with one
collector array and one storage reservoir. The pumps are controlled so as to optimise the heat energy
obtained from the solar collector array, according to the solar irradiation and the temperatures which arise in
the solar energy system. With the heat energy thus obtained, the storage reservoir can be loaded, e.g. a
domestic water storage tank or a swimming pool.

1.1. Information regarding operation
Note!
The solar energy system is configured by your heating engineer during commissioning and operates in
a fully automatic manner. Even during long periods of absence (e.g. holidays), do not switch the solar
energy system off.
!
2. Appropriate usage
The controller is intended for the control of thermal solar energy systems for hot water and heating support
with one collector array and one storage reservoir. Usage for any other purpose is not permitted and does not
apply as appropriate usage. The controller meets the latest technological standards and the applicable safety
regulations of the EMC Directive (2004/108/EC), the Low Voltage Directive (2006/95/EC) and the harmonised
standards DIN EN 60730-1 and DIN EN 60730-2-9.
The controller may only be installed and operated in:
dry environments which are not potentially explosive
closed rooms
rooms with a temperature between 0 °C and + 50 °C
3. Safety instructions
Danger of electrocution!
The controller is to be assembled, electrically installed, commissioned, inspected and repaired by
trained, competent and authorised persons (qualified electricians as per DIN VDE 1000-10 and
BGV A3) only!
Observe all applicable guidelines and regulations of the local electricity supplier!
Before beginning installation or repair work on electrical equipment, always ensure complete
disconnection from the mains and secure against reactivation!
Do not work on live parts!
DANGER
Note!
Never bring highly flammable materials into the vicinity of the controller!
Protect the controller against moisture, cold, heat, dust and intense solar irradiation.
The controller may only be used when in technically perfect condition. Any damage which
impairs, or could impair, the safety or proper functioning of the controller must be rectified
immediately by a competent and authorised person!
Do not change any of the parameters which are not described in this operating manual!

4. Guarantee and liability
All regulations regarding guarantee and liability are stipulated within the manufacturer’s general terms and
conditions, and within the respective contractual relationship. Guarantee claims and liability claims are
expressly excluded in the following cases:
If damage has been caused by inappropriate usage of the controller.
In the event of unauthorised opening of the housing, unauthorised on-site alterations or interference with
the control software.
If the electrician has conducted installation or repair work improperly.
In the event of failure to observe safety instructions or working instructions in the operating manual or
commissioning manual.
5. Positioning of manuals
The operating manual and the commissioning manual must be made available to the installer before installation
of the controller begins. They must always be kept near the controller in a legible state, so as to ensure that
they can be accessed quickly when needed.
6. Important functions at a glance
You want: To do this, press: The display shows:
…to query information on your solar energy
system, e.g. present measurements (see
information display submenu, section 9.1)
…the button (once),
beginning in the start display.
…to change the user settings, e.g. the storage
reservoir’s minimum temperature (see user
settings submenu, section 9.2)
…the button (twice),
beginning in the start display.
…to deactivate storage reservoir (summer / winter
operation, swimming pool) (see user settings
submenu, section 9.2)
…the button (twice),
beginning in the start display,
then (once) and
(either two or three times).

7. How your controller is structured
7.1. The display
Your controller has a clearly laid-out display, which shows you information (e.g. present temperatures)
regarding your solar energy system and helps you to adjust values. Once the start display appears, this
means that the controller has been activated correctly and is in operation. The basic structure of the start
display is as follows:
Storage reservoir
Loading pump active
Relay inactive
Collector array temperatureCollector array
Temperature in lover part
of storage reservoir
Temperature in upper part
of storage reservoir
Please note that other symbols or values which are not pictured above can also appear in your controller’s
start display. It is highly likely that your controller will display other temperature values.
These symbols can also appear in the display:
Change value Sensor defective (interruption)
Frost protection active Sensor defective (short circuit)
Display of information which cannot be
changed
Note: collector protection function or
storage reservoir safety function active
Alarm: emergency switch-off
temperature exceeded
Note!
If your controller is displaying the time, the weekday and “OFF”, it is switched off. Clarify the reasons
for this with your heating engineer and, if applicable, reactivate the controller by pressing and holding
the button for at least 5 seconds. As soon as the start display appears, the controller has been
reactivated.

8. Basic menu navigation
You can easily reach any part of the menu with the aid of the four buttons , , and .
Beginning in the start display (see section 7.1 The display), you can use the buttons to change to any
submenu, so as to query or adjust various values.
In general, the following applies:
The button is used for confirming your selection, saving a changed value or switching to a
submenu.
The button is used for discarding your selection, discarding an entered value or leaving a
submenu.
The buttons and are used for scrolling and for changing values.
8.1. Changing to a submenu
Beginning in the start display, press the button or repeatedly until the desired
submenu is displayed.
Confirm your selection by pressing .
8.2. Navigating within a submenu
Use / again to navigate within a submenu until the desired value is displayed
(description of the individual values can be found in the following subsections).
In order to change a value or to confirm a selection, press .
8.3. Adjusting a value
If the symbol appears in the display, you can change the set values:
Use the / buttons to change the value.
Press to confirm your setting, or discard your setting with .

8.4. Leaving a submenu
From anywhere in a submenu, you can return to the main menu without saving changes by pressing .
In addition, the start display is returned to automatically if 60 seconds pass without any button being pressed
(exception: relay test submenu returns to main menu after 30 minutes).
9. Functions and settings
The following menus can be called up from the start display with the buttons and :
1. Information display “INF”
2. User settings “AE”
3. Manual relay adjustment “REL”
9.1. Information display submenu “INF”
In the information display submenu, you can read the values specified below. Press the button while in
the start display. “INF” appears. Confirm your selection by pressing . As long as you are in the
information display submenu, an “i” also appears in the display.
Note!
Depending on the design and configuration of your solar energy system, it may happen that not all of
the values listed below are displayed.
!
In the information display submenu, the temperature values for the collector arrays and storage reservoirs are
shown first:
Temperature of collector array (TC)
SP Storage reservoir temperature in upper part of storage reservoir (TSP)
