Alarm and error codes
SIRe has different alarms and error codes for safe
and problem free operation.
If alarms or error codes have been indicated
these must be reset in order to return to normal
operation, for example activating the heating
again. Fan mode is active even when, for example,
the over heating alarm has been indicated.
Displaying alarm and error codes
In event of alarm or error the alarm/error code
is shown in the status window. In event of alarm/
error code the unit it applies to is displayed.
See Table - Alarms and Table – Error codes.
Reset alarm
Note! Before resetting, check that the fault is
rectified and there is nothing to prevent the unit
from being recommissioned!
When the fault is rectified, the alarm is reset
by pressing the forward arrow and selecting Reset
alarm and then confirm. If several units give an
alarm at the same time, the fact that there are se-
veral alarms is indicated, but only one is shown in
the display. By resetting that alarm the next alarm
can be read.
At the first start up alarm and error codes can
occur, these can usually be reset without action.
Power failure
Note that in case of power failure the time settings
need to be checked, if the time is not set correctly
week program will be affected.
Overheat protection
Only applies to units with internal sensor.The
over heating protection is intended to restrict
the exhaust temperature to +40 °C. At 37 °C
one output step is tripped off. If the temperature
continues to rise all output is interrupted at 40 °C.
If the temperature continues to rise despite this,
for example because of a faulty contactor, the fan
will start to spin at 50 °C to keep the temperature
down. At the same time there is an over heating
alarm (Table - Alarm). At internal temperatures of
+54 °C the fan runs at maximum speed.
If the unit cools the output is engaged again.
The alarm remains in the control unit’s display. If
the unit overheats twice within an hour, the alarm
must be reset before the heating can be engaged
again, the fan operates until the alarm is reset.
Note! In event of repeated alarms and over hea-
ting alarms, carry out a thorough check and if the
fault cause cannot be found contact authorised
service personnel or Frico.
