12.9 Diagnostics menu
Fig. 48 Diagnostics menu
The Diagnosis service menu contains a number of diagnostics tools.
Keep in mind that the installed system determines which items are
displayed.
12.9.1 Function test menu (manual mode)
Active components in the heating system can be tested with the help of
this menu. If Enable function tests is set to Yes in this menu, normal
heating mode for the entire system is shut off. All settings are saved. The
settings in this menu are only temporary and are reset to standard
settings as soon as 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, where the set values for specified
components are tested. You can check whether the mixing valve, pump
or 3-way valve respond appropriately by inspecting the behaviour of the
corresponding component.
E.g. test the DHW circulation pump:
• Off: Pump stops.
• On: Pump starts.
There is an automatic test sequence for the heat pump that tests by turns
the functions of the components of the heat pump. Activating Outdoor
unit test turns on and off the fan, the heating cable, the drip pan heater,
the 4-way valve and both expansion valves. Each component is active for
10 to 20 seconds.
The Evacuate/fill function activates a special operating mode for
evacuation/filling of the cooling circuit in the heat pump that is used if
the amount of refrigerants needs adjustments.
12.9.2 Monitored values menu
This menu contains the heat system settings and measured values. E.g.
the flow temperature or current DHW temperature is displayed.
Here, you can also find detailed information about system units, e.g. the
heat pump module temperature. The information and values that are
provided depend on the system that has been installed. The technical
information of accessory modules and other system units must be
observed.
