About this document
The language of the original operating instructions is English. All
other languages of these instructions are translations of the original
operating instructions. These installation and operating instructions
are an integral part of the product. They must be kept readily
available at the place where the product is installed. Strict
adherence to these instructions is a precondition for the proper use
and correct operation of the product.
The installation and operating instructions correspond to the
relevant version of the product and the underlying safety regulations
and standards valid at the time of going to print. EC declaration of
conformity:
A copy of the EC declaration of conformity is a component of these
operating instructions (fig 8). If a technical modification is made on
the designs named there without our agreement or the declarations
made in the installation and operating instructions on
product/personnel safety
are not observed, this declaration loses its validity.
2 Safety
These operating instructions contain basic information which must
be adhered to during installation, operation and maintenance.
For this reason, these operating instructions must, without fail, be
read by the service technician and the responsible
specialist/operator before installation and operation.
It is not only the general safety instructions listed under the main
point “safety” that must be adhered to but also the special safety
instructions with danger symbols included under the following main
points.

Pump - Wilo Stratos PARA / Yonos PARA (system with ECL)
The pump is factory connected to the ECL controller.
On systems with ECL controller turn the red switch to the right (con-
stant curve) and set it to “Max. pos.” initially. Then set the pump to the
lowest possible position, depending on the heating requirement for
the building - taking into account aspects such as cooling and power
consumption.
Venting: The pump features a built-in venting function, which can
be used when the system needs to be bled. Turn the red switch to
the vertical position. The pump will then run a venting routine that
lasts 10 minutes. There may be some noise during this phase. Once
the 10-minute period is finished, reset the pump according to the
instructions above.
For additional information, see the manual:
Wilo Stratos PARA /
Yonos PARA.
Summer operation
(all pump types)
Outside the heating period, the pump will be disconnected automati-
cally from the heating system. During the summer period, the control-
ler will start the pump for a minute at least once every three days to
prevent the pump from blocking.
Start-up after summer operation - venting
Please note that it may be necessary to vent the system again. To vent
the system, use the vent valve in the substation or on the radiators
and, if appropriate, the air valve at the highest point of the system.
Alternative pump - Grundfos Magna / Alpha2 (system with ECL)
The pump ist factory-set to control mode Auto
ADAPT
without au-
tomatic nicht-time duty. The automatic night-time duty function is
not to be used
.
On systems with ECL select control mode: constant-pressure con-
trol (see chapter on “Setting of control mode”) and then the set-
point is adjusted to the actual system characteristics.
Please see enclosed instructions:

Please note, that the system cannot be vented through the pump.
