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 several alarms is indicated, but only
one is shown in the display. By resetting that
alarm the next alarm can be read.
Overheat protection
Only applies to units with internal sensor.
The over heating protection is intended to
restrict the exhaust temperature to 40°C. At
40°C the valve actuator closes. If the unit
cools below +35 °C, heating is automatically
reengaged. If the temperature should instead
continue to rise, e.g. in the event of a faulty
valve or actuator, the fan starts to speed up at
46 °C to keep the temperature down. At the
same time there is an over heating alarm
A2
.
At internal temperatures of 50 °C the fan runs
at maximum speed.
If the unit cools below 35 °, heating is
automatically reengaged. The alarm remains
in the control unit’s display. If the unit
overheats twice within an hour, the fan
operates until the alarm is reset.
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.
Frost protection function
Only applies to units with internal sensor.
The frost protection function is intended
to prevent the water coil from freezing. If
the internal temperature falls below +5 °C
frost protection alarm
A3
is given, the valve
actuator opens and the fan stops.
Note! In event of repeated alarms,
overheating alarms and frost protection
alarms, carry out a thorough check and if
the fault cause cannot be found contact
authorised service personnel or Frico.
