Safety of electrical appliances for domestic use and similar purposes
The following requirements apply in accordance with EN 60335-1 in order to prevent hazards from occurring
when using electrical appliances: “This appliance may be operated by children aged 8 or over and by people with
full physical, sensory and mental capabilities who have the necessary training and experience to use this type of
appliance. They must be supervised or instructed on how to use the appliance safely and on the associated risks.
Children must not play with the appliance. Children must not clean or service the appliance without supervision.”
“Damaged power cables must be replaced by the manufacturer, the service department or a qualified contractor in
order to prevent hazards.”
2.1 SAFETY, CONTROL AND PROTECTION DEVICES
2.1.1 HIGH PRESSURE SWITCH
If the operating pressure is outside of the recommended range, the pressure switch switches off the appliance and
displays a fault.
2.1.2 HIGH LIMIT SAFETY CUT-OUT
The high limit safety cut-out ensures that the water temperature in the cylinder does not exceed the prescribed limit.
If the temperature limit is exceeded, the DHW heating shuts down. The reset is performed manually by a certified
contractor.
2.1.3 TEMPERATURE SENSOR FOR AIR INLET
The temperature sensor measures the temperature of the inlet air in the evaporator. If the measured value is outside
the operating temperature range, DHW heating automatically switches from the “Combi” operating mode to “Electric
booster heater”. If the appliance is in the “Heat pump” operating mode, DHW heating is interrupted until the
temperature returns to within the permissible range.
