The meaning of display indications
Performance indicator
The performance indicator shows the currently used performance
of the continuous-flow heater in 10 % increments.
Example: 7 increments are shown while drawing off hot water.
This means that the continuous-flow heater is currently only run-
ning at 70 % of its maximum output.
If the set temperature cannot be reached because the water
throughput is too high, the continuous-flow heater will automati-
cally adjust the water throughput until the set temperature is
achieved.
Pre-warmed water
The continuous-flow heater can be operated with pre-warmed wa-
ter (for example from a solar energy unit) . If the supply tempera-
ture exceeds 30 °C, the lights up on the display.
Flashing display
Risk of scalding!
If the temperature display flashes, the temperature of the water
leaving the tap is higher than the set temperature.
The supply temperature from the domestic system is too high, e. g.
water from a solar energy unit.
The thermostatic premixer in the domestic supply must be set ac-
cordingly to lower temperatures.
Error signals
Sometimes e. g. E02 (or E03 to E14) appears in the display due to
a very minor problem. Please try to eliminate the fault according
to guidelines given in the chapter "A fault, what to do?". You will
save yourself the cost of an unnecessary visit by customer service
personnel.
