Alarm
Cause
Action
A1 Motor alarm
Thermal switch has deployed.
One or several motors have
overheated. (Only units with
withdrawn thermal switches.)
Check that nothing is obstructing the unit’s
air intake and exhaust. When the overheated
motor has cooled the thermal switch
shuts again and the alarm can be reset. At
repeated alarms, check the motors, replace
damaged motors.
A2 Over heating
alarm
The temperature in the unit has
exceeded the alarm limit for
overheating. (Only applies to units
with internal unit temperature.)
Check that nothing is obstructing the unit’s
air intake and exhaust, the function of the
actuator and valve, flow temperature and
internal temperature sensor.
A3 Frost protection
alarm
The temperature in the unit has
fallen below the alarm limit for
frost protection. (Only applies
to units with internal unit
temperature.) The water return
temperature has fallen below the
alarm limit (only when the return
temperature sensor is used).
Make sure that the ambient temperature
where the air curtain is installed exceeds
+5°C. Check the flow temperature, the flow
of hot water and the function of the actuator
and valve. In event of an alarm there a risk
that the battery is damaged, check carefully
for leakage and replace the battery if
damaged.
A4 Filter alarm
Fixed run time before the filter
alarm has been reached.
Replace or clean the filter, adjust any alarm
time based on how dirty the filter was and
reset the alarm.
