- If the red LED "error" lights up continuously the max
level has been exceeded and the overflow sensor has
been reached. The safety chain is opened.
This interrupts the power supply to the condensing
boiler.
The feed pump stays in operation.
- If the level drops below the max level again the safety
chain is closed The red LED goes out.
- If the red and yellow LEDs are flashing there is an
enduring fault with the feed pump. The safety chain of
the condensing boiler remains open until the fault is
rectified.
- If only the red LED is flashing there is an enduring
fault on the level sensors. The safety chain of the
condensing boiler remains open until the fault is
rectified.

6 Maintenance
d
Danger!
Switch the condensing boiler off before
maintaining the device (mains switch and
fuses)!
Switch the power supply off before opening the
cover on the feed pump control!
The neutralisation device must be checked at least once
a year. Consumed neutralisation medium should be
replaced. The effectivity of the neutralisation is checked
using pH paper. This is done by wetting the pH paper
with the condensed water draining from the hose. If you
obtain a reading of less than 6.5 the neutralisation
device must be cleaned immediately and be re-filled with
10 kg of neutralisation medium.
This neutralisation medium is ecologically harmless and
can be disposed of in the buider's waste or household
waste.
a
Caution!
When the installation is maintained the level
sensors must be cleaned at the accessible
locations with a vinegar-soaked cloth.
In addition, you must check whether the
strainer in the condensed water inlet has
become blocked.
