Before you call a heating specialist, check: electrical fuses, main installation
switch, burner function, heat medium pump, valve, fault display, time and day of
the week for the EQJW245.
Displaying faults 7.1
An operating fault is shown on the display by the fl ashing fault symbol (see
section 2.6). The ‚Error‘ message is shown. Push the input knob to open the error
level. In some cases, you can poll to check for multiple faults by turning the input
knob. As long as an acute operating fault is present, the error message is kept in
the display loop, even if it is not opened by pushing the input knob. The error is
shown in the error level according to the list below.
In the fi rst three minutes after you switch the controller on, evaluation and display
of faults is suppressed to wait until other parts of the installation are switched on.

7.1.2 Device status
The device status register contains the information on faults that are present
according to the error list, in coded form. The register can be read with the help
of the service parameters, the communication parameters or via the Modbus. If
a fault message is sent via SMS or Modbus, the fault is notifi ed in the form of the
device status. The coding is as follows:-
Err 1 ( sensor failure, terminal 23 / T
F1
) « 1
Err 2 (sensor failure, terminal 25 / T
F2
) « 1
Err 3 (sensor failure, terminal 26 / T
A
) « 1
Err 4 (sensor failure, terminal 28 / T
R1
, T

) « 1
Err 5 (sensor failure, terminal 29 / T

) « 1
Err 6 (sensor failure, terminal 31 / T
