15 Fault tracing support
If a fault is displayed, it is always practical to select the Main menu, operating line ”Faults
> Faults current”
, and look for any pending fault status messages before starting to
rectify a fault. If an extension module is faulty, that fault must be corrected first because
it can lead to sub sequential fault status messages.
For a detailed description of the display, acknowledgement and resetting of faults, refer
to subsection 13.5.1 “Acknowledgement and reset“.
15.1 Fault code list
The RMK770 controller has maximum 1 heating circuit and 1 time switch. Index 1
indicates that the fault occurred on this plant.
The table below contains the fault number texts with which the controller is supplied.
Texts with designations of aggregates, such as [Boiler …], [Primary controller] and
[Heating circuit], can be changed on the password level.
Number Name (as supplied) For explanation, refer to section …
