Information about the appliance

3.10 Safety, control and protective devices

3.10.1 High-pressure/low-pressure pressure switch

The pressure switch protects the refrigerant circuit from overpressure.
The pressure switch switches off the appliance in the event of
overpressure. An automatic reset occurs as soon as the pressure in the
refrigerant circuit has been regulated.

3.10.2 High limit safety cut-out

The high-pressure safety cut-out ensures that the storage tank's water
temperature does not exceed the prescribed limit. If the temperature
rises above the limit, the heating process is interrupted. The reset is
performed manually by an authorised contractor.

3.10.3 Temperature sensor for air inlet

The temperature sensor measures the temperature of the inlet air in the
evaporator. If the measured value is outside operating temperature
range, DHW production automatically switches from "Combi" operating
mode to "Electrical" operating mode. If the appliance is in "Heat"
operating mode, production is stopped until the measured value is
within operating temperature range.

3.11 Corrosion protection

The internal wall of the DHW storage tank is glass lined (double coating).
As an additional corrosion protection measure, the storage tank is
equipped with an internal magnesium anode. It must be inspected at
regular intervals and replaced if necessary.
First maintenance must be performed 6 months after
installation.
In regions with more corrosive water, special safety measures (filter,
etc.) must be taken, and the magnesium anode must be serviced at
shorter time intervals.
