Wire the enclosed 3-pole connector to the pump with L-PE-N (cable
type: H05VV-F 3 x 0.75 mm²) and plug it into the socket.

Connection of the buer sensor to the pellet replace
Note! Mixing up the buer sensors!
In order to prevent the top and bottom buer sensors from
getting mixed up, the enclosed connectors are coded, i.e. the
connectors only t into the corresponding socket. You can
recognise the same coding by the same colour (pastel blue and
light blue). Install the enclosed top and bottom buer sensors
on the buer.
Attention! Product damage owing to malfunctions!
Swapping the sensors on the buer results in malfunctions.
●Lay the buer sensor cable to the pellet replace, the buer
sensor cable can be extended by max. 15 m if necessary (ca-
ble type: H05VV-F 2 x 0.75 mm² to 2 x 1.5 mm²).
●Wire the top buer sensor with the pastel blue connector
appropriately for the socket and plug it into the socket.
●Wire the bottom buer sensor with the light blue connector
appropriately for the socket and plug it into the socket.
General regulated function
In principle, heating operation of the LEVANA AQUA is regulated
using the “Manual” or “Automatic” operating mode (see “Menu selec-
tion” chapter). I.e., in manual mode the pellet replace heats at
the selected output stage (1-5) until the control temperatures are
reached on the water side.
Note! In automatic mode, the pellet replace heats until either
the room temperature selected or the water-side control
temperatures are reached.
Water-side control function – operation with buer
In Germany, operation without a buer is prohibited by the 1st
BImSchV (Federal Emission Control Act). For pellet replaces, 20 l of
buer volume must be available per kW of water output.
Note! Olsberg also recommends the installation of a buer in
all other distribution countries.
The buer installed is automatically detected by the pellet replace
when it is switched on through querying of the two buer sensors.
Always install both buer sensors for operation with a buer!
During operation with the buer, the pellet replace regulates
according to the “Buer ON” and “Buer OFF” temperatures values,
which can be set individually. The pump only switches on if both of
the following conditions are met:
ū The boiler temperature (water temperature in the pellet replace)
must be greater than 60 °C.
ū The boiler temperature must be 5 °C greater than the dened
“Buer ON” temperature.
The pump switches o if one of the following conditions is met:
ū The boiler temperature must be less than 55 °C.
ū The boiler temperature must be less than the dened “Buer ON”
temperature plus 5 °C.
Note regarding operation without a buer (not permitted
in Germany)!
In the event of operation without a buer, the pellet replace regu-
lates according to the boiler temperature, which is measures in the
pellet replace above the combustion chamber. If the temperature
falls below the boiler temperature of 65 °C, then “Heating operation”
is enabled, and if the temperature falls below 81 °C, then the pellet
replace switches to “Burnout”. The pump switches on at a boiler
temperature of 60 °C and switches o again if the temperature falls
below 55 °C.
