What to do if my ZIEHL-ABEGG Control Unit displays 'Sensor 1'?
If your ZIEHL-ABEGG Control Unit displays 'Sensor 1', it indicates an interruption or short circuit in the sensor leads, or the sensor values measured are outside the measuring range. The device will operate with minimal or maximum modulation, depending on the programmed mode. Check the sensor.
What to do if my ZIEHL-ABEGG Control Unit displays 'Sensor2'?
If your ZIEHL-ABEGG Control Unit displays 'Sensor2', it indicates an interruption or short circuit in the sensor leads, or the sensor values measured are outside the measuring range. The device will operate with minimal or maximum modulation, depending on the programmed mode. Check the sensor.
What does it mean if my ZIEHL-ABEGG Control Unit shows 'External error * EC Motors Filter Frost protection Adiabatik Firealarm Pressure switch Gas alarm Water alarm RCD'?
This indicates an alarm from an external contact. The ZIEHL-ABEGG Control Unit will continue working unchanged. Check the contacts.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Modulation Filter **'?
This indicates a limit alarm modulation. The ZIEHL-ABEGG Control Unit continues working unchanged; limit indication depends on modulation.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Lmt E1 min Filter **'?
This indicates a limit indication minimum, meaning the signal actual value at 'E1' is below setting. The ZIEHL-ABEGG Control Unit continues working unchanged; limit indication depends on setting or sensor signal.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Lmt E1 max. Filter **'?
This indicates a limit indication maximum, meaning the signal actual value at 'E1' is above setting. The ZIEHL-ABEGG Control Unit continues working unchanged; limit indication depends on setting or sensor signal.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Lmt E2 min. Filter **'?
This indicates a limit indication minimum, meaning the signal actual value at 'E2' is above setting. The ZIEHL-ABEGG Control Unit continues working unchanged; limit indication depends on setting or sensor signal.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Lmt E2 max. Filter **'?
This indicates a limit indication maximum, meaning the signal actual value above setting. The ZIEHL-ABEGG Control Unit continues working unchanged; limit indication depends on setting or sensor signal.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Offset 1 Filter **'?
This indicates a limit alarm deviation from Offset 1 is too high. The ZIEHL-ABEGG Control Unit continues working unchanged. Limits depend on the deviation from the setpoint.
What does it mean if my ZIEHL-ABEGG Control Unit displays 'Offset 2 Filter **'?
This indicates a limit alarm deviation from Offset 2 is too high. The ZIEHL-ABEGG Control Unit continues working unchanged. Limits depend on the deviation from the setpoint.
