Changes must be made during the installation for the proK-
lima or KfW label.
Setting for proKlima
▶
Remove the bypass and replace it with the plug that is
supplied.
▶
Set D.014 to 6 (= auto (Δp limit)).
▶
If required, adjust D.122 (set to 200 mbar as standard).
◁
The hydraulic pressure difference with respect to the
heating system is limited to the set value (see dia-
gram).
Note
When starting up the product or after switching
on the power supply, this pump setting does
not take effect until after the burner has run for
the first time.
Setting for KfW
▶
Set D.014 to 7 (= fixed (Δp Limit)).
Conditions: The hydraulics in the heating system or the heating sys-
tem itself is suitable for this type of pump operation.
–
The pump is only operated at this pump speed.
The hydraulic power of the pump for transferring
the heat output is limited.
◁
The pump is permanently set to a lower pump speed
with a maximum feed head of 200 mbar.
Note
If the heating system is not suitable for this
type of pump operation, this can lead to in-
sufficient supply to the product and to safety
shutdowns.
▶
Make sure that there is a guaranteed minimum flow of
heating water via the heating system to transfer the heat
output.
