7.4 Diagnosis
Fig. 9 Diagnosis menu
The Diagnosis service menu contains a number of tools for
diagnosis. Note that the menu items shown will vary depending
on the heating system.
7.4.1 Function tests
This menu can be used to test active system components
individually. If
Enable function tests is set to Yes in this menu,
the normal heating operation is interrupted in the entire
system. All settings are saved. The settings in this menu are only
temporary and revert to the respective default settings as soon
as the
Enable function tests is set to No or the Function test
menu is closed. The available functions and the possible
settings vary depending on the system installed.
A function test is performed by setting the parameters of the
listed component accordingly. You can check whether the
mixer, pump or valve responds appropriately by inspecting the
behaviour of the corresponding component.
The solar pump can be tested, for instance:
• Off : The pump stops.
• On : The pump starts.
7.4.2 Monitored values
System settings and measurements are displayed in this menu.
For example, the system can display whether the maximum
collector temperature or the current cylinder temperature has
been reached.
You can also call up detailed information on system parts, e.g.
the swimming pool. The information and values that are
provided depend on the system that has been installed.
Observe the technical documentation for modules and other
system components.

The current faults and the fault history can be called up in this
menu.
