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
(Quick Guide).
Reset alarm
Note! Before resetting, check that the fault is
rectified and there is nothing to prevent the
unit from being recommissioned.
If several alarms occur, scroll down to view
next alarm, however the alarms must be reset
in the same order.
When the fault is rectified, the alarm is
reset by pressing the forward arrow and se-
lecting Reset alarm and then confirm. 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 overheat protection is primarily intended
to prevent the unit from overheating and
protect the unit and its surroundings from
damages, should an overheating occur. It will
do this by reducing the power output to keep
the internal temperature within its limits, see
table.
If the internal temperature rises above its
alarm limit, an A2 Overheat alarm is trigge-
red and the fan will start running in order to
evacuate the heat. If the internal temperature
continues to rise despite this, for example
because of a faulty contactor or an incorrect
water valve, the fan speed will increase until
full speed is reached and will continue run-
ning until the internal temperature is reduced
and the alarm is reset.
The alarm remains in the display until it
is reset. For electrically heated units the heat
will remain off until then. For water heated
units the actuator/valve will reengage when
internal temperature has fallen to safe levels,
even if the alarm is not yet reset.
For correct function, water heated units
must be equipped with actuator/valve control-
led by SIRe. Electrically heated units are also
equipped with a mechanical over heat protec-
tion.
