2.4 SD memory 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 visualised, e. g. in a spreadsheet.
• Prepare adjustments and parameterisations on a computer
and transfer them via the SD card.
• Store adjustments and parameterisations on the SD card
and, if necessary, retrieve them from there.
• Download  rmware updates from the Internet and install
them on the controller.
For more information about using an SD card, see page 65.
3 Step-by-step parameterisation
The SC5.14 controller 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 con guring them. Therefore,
to set up a complex system, careful planning is required.We recommend drawing
a sketch of the system  rst.
If planning, hydraulic 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
• Hydraulic variant
At the end of the commissioning menu, a safety enquiry follows. If the safety en-
quiry is con rmed, the adjustments will be saved.
For further information about the commissioning menu see page 13.
With an SD card, the following functions can be carried out:
Prepare adjustments and parameterisations on a computer
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 67.
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 con-
troller always suggests the numerically smallest free relay.
Sensors can be allocated to more than one function.
For further information about the optional arrangement functions see page 33.
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 con-
troller always suggests the numerically smallest free relay.
Sensors can be allocated to more than one function.
For further information about the optional arrangement functions see page 46.
5. Adjusting heating circuits and activating optional heating functions
Now, heating circuits can be activated and adjusted.
For the heating part of the arrangement, optional functions can be selected, acti-
vated 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 sug-
gests the numerically smallest free relay.
Sensors can be allocated to more than one function.
For further information about heating circuits and optional heating functions see
page 56.

5.2 Basic systems and hydraulic variants
System
In addition to the pre-con gured schemes 881 and 882, the controller is pre-pro-
grammed for 7 basic solar systems.The selection depends on the number of heat
sources (collector  elds) and heat sinks (stores, pool). Factory setting is system 1.
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 hydraulic variant.
The selected system is visualised by the corresponding number of store and collec-
tor symbols. The  gure to the left shows system 6 which consists of 3 stores and 2
collector  elds (“east- / west collectors”).
A solar system with store charging in layers is
implemented as a 2-store system (store top =
store 1; store bottom = store 2).
System 0: no solar system
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
Variant
The hydraulic variant refers to the different actuators that are to be controlled.
They are visualised on the display by means of symbols, when the variant is select-
ed. 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 all combinations are shown in chap. 5.3.
