KT-Elektronik SOL3-3
8 Malfunction
A system malfunction is indicated by a flashing icon in the display. An error message is
immediately displayed. The error level is opened by pressing the rotary pushbutton. A
larger number of error messages might eventually be retrieved by turning the rotary
pushbutton. Error messages for critical malfunctions are kept in the display loop even if
the details are not opened by pressing the rotary pushbutton.
At error level, the error messages are displayed according to the following list.
Note: After a system variant ID change, eventual error messages are suppressed for
around three minutes after the change.
8.1 Error list

Err 1 = sensor failure (chapter 8.2)

Err 2 = reserved

Err 3 = reserved

Err 4 = maximum charge temperature reached

Err 5 = reserved

Err 6 = temperature monitoring alarm(chapter 8.3)

Err 7 = unauthorized access captured (chapter 8.3)
8.2 Sensor failure
According to the error list, sensor failures are indicated by the message "Err 1" at error
level. Detailed informations can be retrieved at information level by querying the
temperature values. Each sensor icon combined with three small horizontal bars instead
of a temperature value indicate a faulty sensor. The following list describes how the
controller behaves in case of a sensor failure for each single sensor.

Flow sensor, solar circuit: If a primary flow sensor fails, the domestic water is not
heated up any more.

Storage sensor SF1/2: If one of these sensors fails, the buffer storage is not
charged any more.
