ANODE:

Your DHW HP has a high quality steel tank for the DHW generation. This tank inside is enamelled and gives you already a
nearly perfect protection against corrosion. Nevertheless even the superior quality enamel has impurities or zones with
micro-pores. We therefore added a catholic protection (magnesium anode) that ensures the best possible protection
against corrosion. The anode is situated in the middle of the DHW tank (some models has 2 pcs.). The anode is essential
for the prevention of corrosion. As the anode is worn by the use, it has to be checked yearly and to be replaces if
necessary. If you have a model with a signal anode, the display informs you, when the signal anode has to be replaced.

SIGNAL ANODE:

(Models equipped with signal anode only)
Menu settings: If the signal anode is factory mounted (order code 489202), the value of the parameter "ANODE" is
already set to "ON". If the signal anode is retrofit, the parameter "ANODE" has to be set manually to "ON". If a standard
anode is installed, the parameter "ANODE" has to be set to the value "OFF".
The signal anode function: If the signal anode is used and needs replacement, the alarm code "9" will appear on the
display. Call your installer for maintenance and the replacement of the signal anode. Note: while the signal anode alarm
reminds for anode replacement, the DHW HP operates without any restriction. Attention: The signal anode is
deactivated if the "ANODE" parameter value is set to "OFF". See page 21 "maintenance of the anode".
The signal anode function requires the software release 1.31 (or higher) that supports the features like solar cells, holiday
and boost. The signal anode can be retrofit. Please note that the wiring of the solar cell inverter is different to previous
software releases.
