1.1. How to retrieve error codes

When a problem happens, an error code appears on the user interface. It is important to understand the problem and to take
countermeasure before resetting the error code.
For the Altherma Monobloc CA, there are 3 types of troubleshooting codes:
1. Error: a severe problem, system will preventively shut down to prevent further breakdown and the error code will be displayed
on the user interface where it is visible for the end user. Installer should be notified to come on site and repair the problem. All
errors are listed in the Error History [6.3.1] which is only visible when in installer level.
2. Warning: not a severe problem but might lead to an error in case it occurs a number of times within a certain time frame. The
system will not stop but the i-symbol (information) will be blinking. All warnings are listed in the Warning History [6.3.3] which
is only visible when in installer level.
3. Caution: not a severe problem but a sort of alert that the unit will start monitoring a certain event, which might over time result
in an error or a warning. Cautions are not listed.
You can see the error code / warning by pressing the i-button.
Now you can read the error code / warning and a short indication about the problem.
