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 3 mm.
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 re-
move 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 fastening points (centres 150 mm)
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 chap. 2.2
ÎPut the cover on the housing
ÎAttach with the fastening screw

Note:
The pump speed must be set to 100 % when
auxiliary relays or valves are connected.
WARNING! Electric shock!
Upon opening the housing, live parts
are exposed.
ÎAlways disconnect the control-
ler from power supply before
opening the housing!
ATTENTION! ESD damage!
Electrostatic discharge can lead to da-
mage to electronic components!
ÎTake care to discharge proper-
ly before touching the inside
of the device! To do so, touch
a grounded surface such as a
radiator or tap!

The controller is supplied with power via a mains cable.
The power supply of the device must be 100 ...240 V~
(50 ...60 Hz).
The controller is equipped with 4 relays in total to which
loads such as a pump, a valve, etc. can be connected:
• Relays R1 ... R3 are semiconductor relays, designed for
pump speed control
Conductor R1... R3
Neutral conductor N
Ground terminal
• Relay 4 is a standard relay
Conductor R4
Neutral conductor N
Ground terminal
Depending on the product version, mains cable and sensor
cables are already connected to the device. If that is not the
case, please proceed as follows:
Connect the temperature sensors (S1 to S5) to the
corresponding terminals with either polarity:
S1 = sensor 1 (collector sensor )
S2 = sensor 2 (e. g. store sensor base)
S3 = sensor 3 (e. g. store sensor top)
S4 = sensor 4 (e. g. store sensor store 2)
S5 = sensor 5 (e. g. collector sensor collector 2)
Connect the Grundfos sensors to theVFS and RPS inputs.
A V40 owmeter can be connected to the terminalsV40
and GND (either polarity).
The terminals marked “PWM” are control outputs for a
high-efficiency pump (PWM1 is allocated to R1 and PWM2
is allocated to R2).
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)
Ground terminal
WARNING! Electric shock!
Upon opening the housing, live parts
are exposed.
ÎAlways disconnect the control-
ler from power supply before
opening the housing!
Note:
Connecting the device to the power supply must
always be the last step of the installation!
Note:
For more details about the initial commissioning
procedure, see chap. 5, page 73.
Note:
The connection depends on the system selected,
see chap. 2.6.“System layouts”

2.3 Data communication / Bus
The controller is equipped with an SD card slot for storing
system data onto an SD card.The values can be opened and
visualised, e. g. in a spreadsheet programme.
Note:
Do not use an SD-HC card!
A standard SD card is not included with the Level5.
For more information about using an SD card, see chap. 6.2
(page 93) “SD card“.
2.4 SD card slot
The controller is equipped with the VBus®for data transfer
with and energy supply to external modules. The connec-
tion is carried out at the two terminals marked “VBus” and
GND (any polarity). One or more VBus®modules can be
connected via this data bus, such as:
• GA3 Large display module / Smart Display SD3
• AM1 Alarm module
• DL2 Datalogger
Furthermore, the controller can be connected to a PC via
the VBus®/USB or VBus®/LAN interface adapter (not in-
cluded with the Level5).With the ServiceCenter Software,
measured values can be read, processed and visualised.The
software allows easier function control and adjustment of
the system.
Note:
For more information about accessories,see p.101.

Solar system with 1 store and afterheating
The controller calculates the temperature difference bet-
ween collector sensor S1 and store sensor S2. If the diffe-
rence is larger than or identical to the adjusted switch-on
temperature difference, the pump (R1) will be switched on
and the store will be loaded until the switch-off temperature
difference or the maximum store temperature is reached.
Domestic hot water afterheating (R4) can be carried out
with a thermostat function (S3). If the value at S3 reaches
the switch-on temperature for the afterheating, the relay is
energised. If the value exceeds the switch-off temperature
for the afterheating, the relay is switched off again.

The controller compares the temperature at sensor S1 to
the temperatures at sensors S2 and S3.If the measured tem-
perature differences are higher than the adjusted switch-on
temperature differences, the pump (R1) will be activated and
the corresponding store zone will be loaded up to the adju-
sted maximum temperature via the valve (R3).The priority
logic effects prior loading of the upper zone of the store.

The controller compares the temperature at sensor S1 to
the temperatures at sensors S2 and S4. If the measured tem-
perature differences are higher than the adjusted switch-on
temperature differences, the pump (R1) will be activated and
the corresponding store will be loaded up to the adjusted
maximum temperature via the valve (R3). Store 1 is loaded
with priority.

2-store solar system with pump logic
The controller compares the temperature at sensor S1 to
the temperatures at sensors S2 and S4. If the measured
temperature differences are higher than the adjusted switch-
on temperature differences, the pump (R1 and R2) will be
activated and the corresponding store will be loaded up to
the adjusted maximum temperature at most.
