2 Installation
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the controller from power supply
before opening the housing!
2.1 Mounting
The unit must only be located in dry interior rooms.
The controller must additionally be supplied from a double pole switch with
contact gap of at least 3mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
ÎUnscrew the cross-head screw from the cover and remove it along with the
cover from the housing
ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding
ÎHang the housing from the upper fastening point and mark the lower fasten-
ing points (centres 150mm)
ÎInsert lower wall plugs
ÎFasten the housing to the wall with the lower fastening screws and tighten
ÎCarry out the electrical wiring in accordance with the terminal allocation,
see page 6
ÎPut the cover on the housing
ÎAttach with the fastening screw
Note
Strong electromagnetic fields can impair the function of the controller.
Make sure the controller as well as the system are not exposed to
strong electromagnetic fields.

2.2 Electrical connection
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the controller from power supply
before opening the housing!
WARNING! ESD damage!
Electrostatic discharge can lead to damage to electronic
components!
ÎTake care to discharge properly before touching
the inside of the device!To do so, touch a grounded
surface such as a radiator or tap!
Note
Connecting the device to the power supply must always be the last step
of the installation!
Depending on the product version, cables are already connected to the device. If
that is not the case, please proceed as follows:
The controller is equipped with 5 relays in total to which loads such as pumps,
valves, etc. can be connected:
Relays 1 ... 4 are semiconductor relays, designed for pump speed control:
Conductor R1… R4
Neutral conductor N (common terminal block)
Protective earth conductor PE ⏚(common terminal block)
Relay 5 is a potential-free relay (normally open contact): Connections to the R5
terminals can be made with either polarity.

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.
• Prepare adjustments and parameterisations on a com-
puter and transfer them via the SD card.
• Store adjustments and parameterisations on the SD card
and, if necessary, retrieve them from there.
• Download firmware updates from the Internet and install them on the con-
troller.
For more information about using an SD card, see page 50.
With an SD card, the following functions can be carried out:
Temperature sensors (S1 to S9) have to be connected to the terminals
S1… S9 and GND (either polarity).
The terminal S9 can be used as an impulse input for a V40 flowmeter or a FS08
flow switch.
A V40 flowmeter can be connected to the terminals S9/ V40 and GND (either
polarity).
Connect the irradiation sensor CS10 to the terminals CS10 and GND with
correct polarity.To do so, connect the cable marked GND to the GND common
terminal block, the cable marked CS to the terminal 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 RPD andVFD inputs.
The controller is supplied with power via a mains cable.The power supply of the
device must be 100…240V~ (50… 60 Hz).
The mains connection is at the terminals:
Neutral conductor N
Conductor L
Conductor L' (L' is not connected with the mains cable. L' is a fused contact
permanently carrying voltage)
Protective earth conductor PE ⏚(common terminal block)
WARNING! Electric shock!
L' is a fused contact permanently carrying voltage.
ÎAlways disconnect the controller from power supply
before opening the housing!
Note
For more details about the initial commissioning procedure, see page 11.
2.3 Data communication / Bus
The controller is equipped with the RESOL VBus®for data transfer with and
energy supply to external modules. The connection is carried out at the two
terminals marked VBus and GND (either polarity). One or more RESOL VBus®
modules can be connected via this data bus, such as:
• RESOL AM1 Alarm module
• RESOL DL2 Datalogger
• RESOL EM Extension module
Furthermore, the controller can be connected to a PC via the RESOLVBus®/USB
orVBus®/LAN interface adapter (not included).With the RESOL ServiceCenter
Software (RSC), measured values can be read, processed and visualised.The soft-
ware allows an easy function control of the system.

ment range depending on the adjustment of the respective other value.
In this case, the active area of the slide bar is shortened, the inactive area is indi-
cated as a dotted line.The indication of the minimum and maximum values will
adapt to the reduction.
If only one item of several can be selected, they will be indicated with “radio but-
tons”. When one item has been selected, the radio button in front of it is filled.
If more than one item of several can be selected, they will be indicated with

4 Commissioning
4.1 Initial commissioning
When the hydraulic system is filled and ready for operation, connect the control-
ler to the mains.
The controller runs an initialisation phase in which the directional pad flashes red.
When the controller is commissioned for the first time or when it is reset, it
will run a commissioning menu after the initialisation 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 ➄.Adjust the value by pressing but-
tons ❷and ❹, then push button ➄to confirm. The next channel will appear
in the display.

enquiry appears. If the safety enquiry is con-
firmed, the adjustments are saved.
ÎIn order to confirm the security enquiry,
press button ➄.
ÎInordertoreenterthe commissioning menu
channels, press button ➆.
If the security enquiry has been confirmed,
the controller is ready for operation and
should enable an optimum system opera-
tion.
All adjustments made during commissioning
can, if necessary, be changed later on in the ba-
sic settings menu.
6. Basic system:
ÎAdjust the desired scheme (heating circuit,
demand, DHW heating).
4.2 Schemes with basic settings
The controller is pre-programmed for 9 basic systems.The basic pre-adjustments
have already been made. For afterheating it is necessary to allocate the demand
and the boiler loading pump by means of shared relays. Afterwards the system
can easily be extended.
Relay and sensor allocation correspond to the figure.
Scheme 0 has no pre-adjustments.

By means of the flow sensors S1 and S3 respectively and the outdoor tem-
perature sensor S2, one mixed and one unmixed weather-compensated
heating circuit can be controlled. Boiler demand via the potential-free relay
is triggered depending on the temperature difference between the set flow
temperatures and the value measured at the afterheating sensor S4.

By means of the flow sensor S1 and the outdoor temperature sensor S2, a mixed
weather-compensated heating circuit can be controlled.The solid fuel boiler is con-
trolled depending on the temperature difference between the sensors S3 (solid
fuel boiler) and S5 (store).
