ANODE

ANODE:
Hot water tank is internal corrosion protected with enamel. There are in the enamel few small pores, etc., that are not
covered by the enamel. To completely prevent corrosion there is mounted an anode in the middle of the tank to
protect these pores (some models has 2 pcs.). One should ensure that the anode is always intact. This should be done
by inspecting once every year and if necessary replace it. For models with signal anode will emerge an alarm when it
needs replacing. This alarm does not lock the daily operation.

SIGNAL ANODE:

Models, that are equipped with signal anode. The anode menu will show "AUTO", and alarm nr. 9 will show, if the
anode is used and has to be replaced. If the anode menu shows "manual", there are none automatic control function
for used anode. See page 18 "maintenance of the anode". Also note that models with signal anode is not able to have
features like solar cells, holiday and boost functions which will not be shown in the display menu.
