just had same problem. this apprently happens if the power supply has been interrupted or you switch the power on and off.
• The boiler runs for 15 minutes at minimum heat output to fill the condensate trap, the display (K) alternates between -II-” and the boiler flow temperature. This occurs every time the mains supply has been interrupted.
