Description
Built-in monitoring has been
activated: the set maximum
temperature at sensor T1
has been exceeded
Built-in monitoring has been
activated: the set minimum
temperature at sensor T1
has been under-run.
The time has been changed
due to daylight-saving.
Low-pressure has been
detected in vessel 1
(upper transmitter of level
measurement L1). Thus
pumps have been disabled.
Maximum temperature
at sensor T2 has been
exceeded. Degassing is
deactivated as long as the
temperature is too high.
After this it will be
enabled again.
Built-in monitoring has been
activated: the set maximum
temperature at sensor T2
has been exceeded
Built-in monitoring has been
activated: the set minimum
temperature at sensor T2
has been under-run
The remaining amount
for the makeup is less
than 20% of the set
maximum amount.
The remaining amount of
the softening cartridge from
MWE is less than 20%.
If the amount is completely
used makeup can't be
used anymore.
Low-pressure has been
detected in vessel 1
(upper transmitter of level
measurement L2). Thus
pumps have been disabled.

Check time and date before
resetting this message.
Pumps get enabled again,
if pressure is in allowed
range and the message
is reset. First check if the
hose from the outside of the
membrane is clear.

The Sensor T2 is decided to
disable degassing in such
situations with too high
temperatures.

It doesn't affect the function
of the device. Check if
consumption is in line with
the usual consumption of
the plant, reset the amount
so the full amount is
available again.
Provide spare cartridge
in time and change it at
latest if the old capacity is
completely used.
Pumps get enabled again,
