– in %, adjustable 0 ... 100 %
n ECO Mode min circulation capacity
– in %, adjustable 0 ... 100 %
n DIN error ➨ Circulation ➨ 100 %:
– Active / inactive
n
[Redox ➨ Circulation (dependency) cor.: inactive]
– Active / inactive
n Circulation reduction =
– in %, adjustable 0 ... 100 %
n Circulation reduction time =
– 0 ... 9999 seconds
CAUTION!
Thermal overloading of the pump motor
Consequence: The pump motor and its surroundings
could be damaged
Measure: Provide the pump motor and/or the fre‐
quency converter with a suitable thermal protection
switch and possibly a fan.
In this respect observe the peculiarities of your local
ambient conditions and your national regulations and
standards.
The operating mode
[ECO Mode min. circulation capacity]
speci‐
fies how far the circulation capacity of the circulating pumps is
reduced in
[ECO Mode]
.
Operating mode
[DIN Error ➨ 100%]
, immediately sets the circula‐
tion operating mode to
[normal mode]
if the active ECO limit value
settings are breached. Otherwise the circulation increases in par‐
allel with the values of the reduction mode.
Operating mode
[Redox ➨ Circulation (dependency) cor.: active]
:
In this operating mode, the reduction rate is influenced by the
actual redox value Start and end redox values are defined. Reduc‐
tion mode is started from the start Redox value. Reduction mode
lowers the circulating pump capacity in steps up until the End
redox value the
[ECO Mode min]
value is reached. If the water
redox value falls below the start redox value, then the circulation
starts again at 100% capacity.
Operating mode
[Redox ➨ Circulation (dependency) cor.: inactive]
:
In this operating mode, the reduction rate
[Circulation reduction %]
and the time period
[Circulation reduction time = seconds ]
are set.
This reduction
[Step reductions]
is continued downwards until the
set value
[ECOMode min]
is reached.
The operating mode
[Circulation reduction in %]
in which the time
period in
[sec]
is set. This reduction
[Step reductions]
is continued
until the set
[ECO Mode min]
value is reached.
