AINTENANCE ATTENTION MESSAGES
The following graphs describe the messages at the water heater display. Depending on the selected and activated
options for the water heater, it is possible that some messages will show up at the display. For example a mainte-
nance message after a certain programmed date has been reached. The water heater will operate independently
of these messages.
The display shows alternating the base screen and this message, while the backlight is blinking.
The water heater is operating, but will count the exceeding hours.
A parameter must be changed, after service, to remove this message.
