Direct Digital Controller fw 4.013 – Ed. 01/2013 149
Operating anomalies may be of two types: warnings or errors.
If a WARNING event arises, the following occurs:
The warning is signalled in the “Error menu” (to access the menu, select
from the main screen);
The warning is signalled in the “Event history” menu;
The relative “warning ON” is memorised in the event history list..
When the warning event is reset, the following occurs:
The warning signals (see above) are reset;
The relative “warning OFF” is memorised in the event history list.
If an ERROR event arises, the following occurs:
The event is shown in the “Error menu” (to access the menu, select
from the main screen);
The display's backlight and the icon flash;
A beeper sounds, if programmed in the “Alarm beeper” menu(see paragraph 3.4.2.4 on page 49);
The signal relay switches, if programmed in the “Configuring alarm output” menu (see paragraph 4.4.2.4
on page 86);
The error status is signalled in the “Machine status” menu;
The error is signalled in the “Event history” menu;
The relative “error ON” is memorised in the event history list.
When the event is reset, the following occurs:
The display and signalling of the error are reset;
The alarm beep is reset;
The flashing signal of the display is reset;
The signal relay is reset;
The relative “error OFF” is memorised in the event history list.
The codes that identify the anomalies are divided on the basis of the type of machine from which they
originate, according to the indications provided in the table below.
UNIT ERROR WARNING
NOTE
DDC 10-- 10--
The code for errors generated by the DDC is composed of four digits: the first
two indicate the type of unit in error status(10 for the DDC), the other two the
error type
ACF 60 0-- 0--
The error code for the DHW module is composed of 3 digits: the first defines
the machine type (0 for DHW), the other two the error type. (*)
AY 00-120 1-- 1--
The error code for the AY module is composed of 3 digits: the first defines the
machine type (1 for AY), the other two the error type.(**)
GAHP-W
GAHP-
GS/WS
2-- 2--
The error code for the GAHP-GS/WS module is composed of 3 digits: the first
defines the machine type (2 for GAHP-GS/WS), the other two the error type.
GAHP-AR 6-- 6--
The error code for the GAHP-AR module is composed of 3 digits: the first
defines the machine type (6 for GAHP-AR), the other two the error type.
GAHP-A 4-- 4--
The error code for the GAHP-A module is composed of 3 digits: the first
defines the machine type (4 for GAHP-A), the other two the error type.
(*) Valid also for the ACF 60 module of AYF 60-119/2, AYF 60-119/4, Prontoclima C and Prontoclima CR units.
(**) Valid also for the AY 00-119 module of AYF 60-119/2, AYF 60-119/4, Prontoclima C and Prontoclima CR units.
The table below indicates the main anomalies, as well as possible intervention to carry out.
