Frequency converter of the extract-air fan notifies a mal-
function. ➜ Check the frequency converter and the thermal
contact or resistor of the motor.

3.1 Motor protec-
tion 1 has trig-
gered!
The frequency converter of the supply-air fan has notified
a fault. ➜ check the frequency converter and the thermal
contact or resistor of the motor.

3.2 Analog input 1 No input signal at the sensor input of the supply-air fan. ➜
Check the 2-10V signal of the sensor, ensure that no 0-10V
sensor is connected.
F
3.3 Analog input 2 There is no input signal at the sensor input of the extract-
air fan. ➜ Check the signal of the 2-10V sensor and ensure
that no 0-10V sensor is connected.
F
3.6 Setpoint Vol-
ume flow 1
A valid setpoint for the supply-air volume flow is not avail-
able. ➜ Specify setpoint.
F
3.7 Setpoint Vol-
ume flow 2
No valid setpoint for the extract-air volume flow available.
➜ Specify setpoint.
F
3.8 Sensor vol-
ume flow 1
A valid actual value for the supply-air volume flow is not
available. ➜ Check sensor signal and range.
F
3.9 Sensor vol-
ume flow 2
A valid actual value for the extract air-volume flow is not
available. ➜ Check sensor signal and range.
F
3.10 Pressure set-
point-
value 1
A valid setpoint for the supply air pressure is not available.
➜ Specify setpoint.
F
3.11 Pressure set-
point-
value 2
A valid setpoint for the extract-air pressure is not available.
➜ Specify setpoint.
F
3.12 Pressure val-
ue 1
A valid actual value for the supply-air pressure is not avail-
able.
➜ Check sensor signal and range.
F
3.13 Pressure val-
ue 2
A valid actual value for the extract-air pressure is not avail-
able.
➜ Check sensor signal and range.

3.14 MATRIX.
EXT-ERS
missing
The circuit board MATRIX.EXT for the control of the energy
recovery cannot be addressed.
➜ Check voltage supply, bus address and function selector
switch.
F
3.15 MATRIX.
EXT frequen-
cy inverter
missing
The circuit board MATRIX.EXT for the control of the fre-
quency inverter cannot be addressed.
➜ Check voltage supply, bus address and function selector
switch.
F
3.16 ERS-inlet
temp.
A controller reports that the measured value of the ERS in-
let temperature is missing or the Al 5 inlet is deactivated.
F
3.17 AK- communi-
cation
A controller reports a communication failure between con-
troller and extender-module with adiabatic cooling function
(humidifier)
F
3.18 ERS-inlet hu-
midity
A controller reports that the measured value of the ERS in-
let humidity is missing or the Al 6 inlet is deactivated.
