Defects

If your storage heater malfunctions, and the display does not show any
error messages, please first check the following:
• Appliance failed to charge:
- If the target charge level rotary knob on the appliance set to zero?
- Are the fuses on the current distribution board loose or defective?
• Appliance fails to discharge via the fan:
- Has the temperature shown on the display been set using the target
room temperature rotary knob to a lower value than the current room
temperature?
- Has the fan been cleared? If the green LED control light is not on, the
fan has not been cleared.
- Are the fuses for the fan circuit on the current distribution board loose
or defective?

The error detection setting in respect of the time is highly sensitive, which means that even very minor irregulari-
ties may result in an error message. Before calling customer service, access the Day/Time menu and set the
time. Only if this error message recurs repeatedly is the error serious enough to call customer service.
Your fitter will naturally be available to assist you in the event of faults.
