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 triggered 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 running 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 controlled by SIRe.
Electrically heated units are also equipped with a
mechanical over heat protection.
