2.4 SD card slot
The controller is equipped with
an SD card slot.
With an SD card, the following
functions can be carried out:
• Store measurement and
balance values onto the SD
card. After the transfer to
a computer, the values can
be opened and visualized, e. g. in a spreadsheet
programme.
• Prepare adjustments and parameterizations on a
computer and transfer them via the SD card.
• Store adjustments and parameterizations on the
SD card and, if necessary, retrieve them from there.
• Download rmware updates from the Internet and
install them on the controller.
en
A standard SD card is not included with the SOM 10.
For more information about using an SD card, see
page 69.
3 Step-by-step parameterization
The SOM 10 is a controller that offers a broad variety
of functions to the user. At the same time, the user has
a lot of freedom in congurating them. Therefore, to
set up a complex system, careful planning is required.
We recommend drawing a sketch of the system rst.
If planning, hydronic execution and electrical connection have all been carried out successfully, proceed as
follows:
1. Running the commissioning menu
The commissioning menu is run after the rst connection and after every reset. It will request the following
basic adjustments:
• Menu language
• Temperature unit
• Volume unit
• Pressure unit
• Energy unit
• Time
• Date
• Solar system
• Hydronic variant
At the end of the commissioning menu, a safety en-
quiry follows. If the safety enquiry is conrmed, the
adjustments are saved.
For further information about the commissioning
menu see page 12.
2. Registering sensors
If owmeters, ow switches, Grundfos Direct Sensors™ and/or external extension modules are connected, these have to be registered in the In-/Outputs
menu.
For further information about the registration of modules and sensors see page 72.
3. Activating solar optional functions
The basic solar system has been adjusted during commissioning. Now, optional functions can be selected,
activated and adjusted.
Free relays can be allocated to optional functions
which require a relay. The controller always suggests
the numerically smallest free relay.
Sensors can be allocated to more than one function.
For further information about the solar optional func-
tions see page 34.
4. Activating optional arrangement functions
Now, optional functions for the non-solar part of the
arrangement can be selected, activated and adjusted.
Free relays can be allocated to optional functions
which require a relay. The controller always suggests
the numerically smallest free relay.
Sensors can be allocated any number of times without
impairing any other functions.
For further information about the optional arrangement functions see page 47.
5. Adjusting heating circuits and activating optional heating functions
Now, heating circuits can be activated and adjusted.
Internal heating circuits are only offered as long as at
least 3 relays are free.
For the heating part of the arrangement, optional
functions can be selected, activated and adjusted.
To heating circuits and optional functions which require one or more relays, the corresponding number
of free relays can be allocated. The controller always
suggests the numerically smallest free relay.
Sensors can be allocated any number of times without
impairing any other functions.
For further information about heating circuits and optional heating functions see page 59.

5 Initial commissioning
When the hydronic system is lled and ready for operation, connect the controller to the power supply.
The controller runs an initialization phase in which
the directional pad ashes red.
When the controller is commissioned for the rst
time or when it is reset, it will run a commissioning
menu after the initialization phase. The commissioning
menu leads the user through the most important adjustment channels needed for operating the system.
Commissioning menu
The commissioning menu consists of the channels
described in the following. In order to make an adjustment, push button
sing buttons 4 and 2, then bush button 5 to

5.1 Basic systems and hydronic variants
System
The controller is preprogrammed for 9 basic systems.
The selection depends on the number of heat sources
(collector elds) and heat sinks (stores, pool). Factory
setting is system 1.
System 0: no solar system
en
System 1: 1 collector eld - 1 store
System 2: east- / west collectors - 1 store
System 3: 1 collector eld - 2 stores
System 4: east- / west collectors - 2 stores
System 5: 1 collector eld - 3 stores
System 6: east- / west collectors - 3 stores
System 7: 1 collector eld - 4 stores
System 8: east- / west collectors - 4 stores
System 9: 1 collector eld - 5 stores
The selection of the basic solar system is one of the
most important adjustments and is thus requested already in the commissioning menu.
First, the basic system is adjusted by means of the
number of stores and collectors elds, then the hydronic variant.
The selected system is visualized by the corresponding number of store and collector symbols. The gure to the left shows system 6 which consists of 3
stores and 2 collector elds ("east- / west collectors").
Variant
The hydronic variant refers to the different actuators that are to be controlled. They are visualized on
the display by means of symbols, when the variant
is selected. The upper symbol indicates the actuator
belonging to the collector elds, the lower one the
actuators belonging to the stores.
The exemplary gure shows the display indicated
when system 6, variant 2 has been selected. In this
case, each collector eld has a 2-port valve, the stores
are loaded by means of pump logic.
For each variant, the controller allocates the corresponding relays and sensors. The allocations of the
most important combinations are shown in 5.2.
A solar system with vertical tank loading is implemented as a 2-store system
(store top = store 1; store bottom = store 2).
