6 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 control button. A larger
number of error messages might eventually be retrieved by turning the control button.
Error messages for critical malfunctions are kept in the display loop even if the details
are not opened by pressing the control button.
At error level, the error messages are displayed according to the following list.
6.1 Error list
Err 1 = sensor failure (chapter 6.2)
Err 2 = reserved
Err 3 = reserved
Err 4 = reserved
Err 5 = reserved
Err 6 = temperature monitoring alarm(chapter 6.3)
Err 7 = unauthorized access captured (chapter 6.3)
6.2 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.
Collector sensor CF1: The collector pump remains turned off on sensor failure.
Storage sensor SF1: The collector pump remains turned off on sensor failure.

Note: After a system variant ID change, eventual error messages are suppressed for
around three minutes after the change.
