(RSC), measured values can be read, processed and
visualised. The software allows easier paramatrisation
and function control of the system.
Parameterising the controller via the RESOL Service-
Center Software is not yet possible. The feature will
be made available in an upcoming firmware version.
The terminal S9 can be used as an impulse input for a
V40 flowmeter or as an input for an FS08 flowswitch.
The V40 flowmeter can be connected to the terminal
S9/V40 and GND (either polariry).
Connect the irradiation sensor CS10 to the termi-
nals CS10 and GND with correct polarity. To do so,
connect the cable marked GND to the GND com-
mon terminal block, the cable marked CS to the ter-
minal marked CS10.
The terminals marked PWM are control outputs
for high-efficiency pumps.
In the In-/Outputs menu, relays can be allocated to
the PWM outputs.
Connect the digital Grundfos Direct Sensors™
to the GDSD1 and GDSD2 inputs.
Note:
If Grundfos Direct SensorsTM are used, con-
nect the sensor ground common terminal
block with PE.
The controller is supplied with power via a mains ca-
ble. The power supply of the device must be 100 ... 240

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 visualised, e. g. in a spreadsheet
programme.
• 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 fi rmware updates from the Internet and
install them on the controller.
A standard SD card is not included with the
D e l t a S o l® BX Plus, but can also be purchased at
RESOL.
For more information about using an SD card, see
page 64.
3 Step-by-step parameterisation
The D e l t a S o l® BX Plus 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 confi gurating
them. Therefore, to set up a complex system, careful
planning is required. We recommend drawing a sketch
of the system fi rst.
If planning, hydraulic execution and electrical connec-
tion have all been carried out successfully, proceed as
follows:
1. Running the commissioning menu
The commissioning menu is run after the fi rst connec-
tion 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 en-
quiry follows. If the safety enquiry is confi rmed, the
adjustments are saved.
For further information about the commissioning
menu see page 12.
2. Registering sensors
If fl owmeters, fl ow switches, Grundfos Direct Sen-
sors™ and/or external extension modules are con-
nected, 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 com-
missioning. 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 29.
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 arrange-
ment functions see page 42.
5. Adjusting heating circuits and activating op-
tional 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 re-
quire 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 op-
tional heating functions see page 54.

7. Selection of the solar system:
ÎAdjust the desired solar system (number of col-
lectors and stores, hydraulic variants).

en
14
5.1 Basic systems and hydraulic variants
The controller is preprogrammed for 9 basic systems.
The selection depends on the number of heat sources
(collector fi elds) and heat sinks (stores, pool). Factory
setting is system 1.
A solar system with store loading in layers is
implemented as a 2-store system
(store top = store 1; store bottom = store 2).
The selection of the basic solar system is one of the
most important adjustments and is thus requested al-
ready in the commissioning menu.
First, the basic system is adjusted by means of the
number of stores and collectors fi elds, then the hy-
draulic variant.
The selected system is visualised by the correspond-
ing number of store and collector symbols. The fi gure
to the left shows system 6 which consists of 3 stores
and 2 collector fi elds ("east- / west collectors").
System 0: no solar system
System 1: 1 collector fi eld - 1 store
System 2: east- / west collectors - 1 store
System 3: 1 collector fi eld - 2 stores
System 4: east- / west collectors - 2 stores
System 5: 1 collector fi eld - 3 stores
System 6: east- / west collectors - 3 stores
System 7: 1 collector fi eld - 4 stores
System Variant
The hydraulic variant refers to the different actua-
tors that are to be controlled. They are visualised on
the display by means of symbols, when the variant
is selected. The upper symbol indicates the actuator
belonging to the collector fi elds, the lower one the
actuators belonging to the stores.
The exemplary fi gure shows the display indicated
when system 6, variant 2 has been selected. In this
case, each collector fi eld has a 2-port valve, the stores
are loaded by means of pump logic.
For each variant, the controller allocates the corre-
sponding relays and sensors. The allocations of the
most important combinations are shown in 5.2.
