CR Remeha Avanta 12v, Installation And Service Manual

Page: 88 / 110

The Remeha Avanta has an advanced control unit. The heart of this control unit is a
microprocessor, the
abc® -control which both controls and protects the boiler. If an
error is detected anywhere in the boiler, it will lock out and an error code will appear
in the display.
4.2 Error codes
The Remeha Avanta displays the error codes as follows: [E][2] (the display
alternately shows an [E] and a number e.g. [2] ). The meaning of the various error
codes can be found in the error table, see table 12 .
How to deal with errors:
• Make a note of the displayed error code.
The error code is important for the correct and swift detection of the nature of
the error and for possible support from our technical help line 0118 974 3070.
•
Press the [reset] -key for 3 seconds. If the error code continues to appear,
look for the cause in the error table below and resolve it.
Error
code Description Possible cause Check / solution
[E][0]
Flow or return
sensor fault.
Short circuit in the
flow, return or
boiler temperature
sensor. Check the wiring and the
connections of the sensors
visually: are
the plugs all correctly in
position?
With a multimeter:
measure the resistance in
the wiring and connection.
Defective or not
(properly) connected
flow, return
or boiler
temperature sensor. Check that the sensors are
working; take the sensors
out* and
measure the resistance
with a multimeter at room
temperature (20 - 25°C);
the sensor is working
properly if the resistance is
between 12 and 15 kOhm.
[E][1]
Flow
temperature is
higher than the
set
maximum
temperature .
Insufficient water. Check the water level and
check for leaks.
No through flow. Check that the pump is
working; turn the spindle
with a screwdriver,
if that works but the pump
still does not respond,
check the wiring; if
that is in order the pump is
faulty.
