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” operat-
ing mode to “Electric booster heater” . If the appliance is in the “Heat
pump” operating mode, DHW heating is interrupted until the tempera-
ture returns to within the permissible range .
2.1.4 PRESSURE RELIEF VALVE
The safety valve should be opened regularly to remove calcium build-
up and to verify that it is not blocked .
2.1.5 PRESSURE REDUCING VALVE
The system must include a pressure reducing valve if the main line
pressure is above 5 bar . The pressure reducing valve must be installed
in the main line . A pressure of 3 to 4 bar is recommended .
