bending points have been set.
If a curve is used, the day number is the basis used to calculate the setpoints from the relevant curve. If
a negative day number is set, the Aura 37 will control without using the curve, until the day number is a
positive number. A negative day number is also increased at midnight by one, except the jump from day
–1 to day +1 (a jump of 2).

If the value responsible for causing the alarm comes within the alarm limits again, the situation is
considered recovered and the alarm is no longer active. The siren automatically disables and the alarm
status changes into Alarm recovered. This message remains visible so you can see what caused the
alarm. Press to change the alarm status into Alarm temp. off followed by Alarm stand by.
If an alarm occurs the ‘menu selection and alarm bar’ will flash red. Perform the following actions in case of a:
1. Press . The alarm overview displays the alarm status Alarm and shows the alarm message.
2. Press once more. The siren will temporarily go off and the alarm status changes to Alarm temp. off. The
alarm message remains visible to investigate what caused the problem.
3. Solve the alarm situation. When the alarm situation is solved the alarm status changes into Alarm stand by.
1. Press . The alarm overview displays the alarm status Alarm and shows the alarm message.
2. Solve the alarm situation.
3. Press once more. The alarm message will disappear and the alarm status changes into Alarm temp. off
followed by Alarm stand by.
If the alarm is disabled the control computer will not generate any alarm messages (except system
alarms). Never switch the alarm off during regular operation.
The alarm can be fully disabled, e.g. when the house is empty. Disable the alarm as follows:
1. Press .
2. Change the alarm status to Alarm disabled. The control computer will give a warning to indicate that the
entire alarm system has been disabled and will flash red.
Reactivate the alarm by changing the alarm status to Alarm stand by. The alarm message states that the alarm


Abs. Maximum alarm
If the house temperature is higher than the set Abs. maximum alarm, the control
computer will give a maximum temperature alarm.
Dif. Maximum alarm
The control computer gives a maximum temperature difference alarm if the house
temperature is above: Calculated end temperature ventilation + Dif. Maximum alarm
(the calculated temperature is shown between brackets).
Calculated end temperature ventilation: 24ºC
Dif. Maximum alarm: 3ºC
Calculated alarm limit: 27ºC
An alarm will occur if a temperature becomes higher than the maximum
alarm limit: 24 + 3 = 27°C.
On hot summer days the temperature in a section can be very high. This
can result in a maximum alarm or the difference alarm will have to be set
high. This is not desirable with lower temperatures; the maximum alarm
limit would then be unnecessarily high. In order to provide effective alarms
(dif. maximum alarm as small as possible) the computer increases the
alarm limit parallel to the outside temperature, as soon as this is higher than
the point at which ventilation is maximum.
Calculated end temperature ventilation: 24ºC
Outside temperature: 25ºC
Max. difference alarm: 3ºC
Calculated alarm limit: 28ºC
An alarm will occur if a temperature becomes higher than the maximum
alarm limit: 25 + 3 = 28°C.
Calculated end temperature ventilation: 24ºC
Outside temperature: 35ºC
Max. difference alarm: 3ºC
Calculated alarm limit: 27ºC
Absolute maximum alarm: 35ºC
An alarm will occur if a temperature becomes higher than the maximum
alarm limit: 24 + 3 = 27°C. The maximum alarm is however limited by the
absolute maximum alarm to 35°C.
Abs. Minimum alarm
If the house temperature is lower than the set Abs. Minimum alarm, the control
computer will give a minimum temperature alarm.

Aura 37
Alarm
17
Dif. Minimum alarm
The control computer gives a minimum temperature difference alarm if the house
temperature is below: Start temperature ventilation - Dif. Minimum alarm.
Start temperature ventilation: 20ºC
Dif. Minimum alarm: 4ºC
Calc. min. alarm limit: 16ºC
An alarm will occur if the temperature becomes lower than 16ºC.
Temperature sensor failure
Measurements from connected sensors (except the outside sensor) are reliable as long as measurements are
between -9.9ºC and +99.9ºC. Outside these limits, the measurements are unreliable. The control computer will
give an alarm. This can mean that the temperature sensor has not been correctly connected or is defective. The
screen displays # at the temperature readout.
