Description Remedy
Data for the control of the mixing-air damper is missing. ➜
Check connection of the feedback potentiometer (for con-
nection, see operation manual of the air treatment unit or
accessory).
The input for the freely configurable operating mode is ac-
tive. In the event of a MATRIX 4700 control, a fire damper
➯
has triggered. Check fire damper.
Digital input "unit OFF" is active. The unit was switched off
➯
externally. Check sensor and external control signal.
Normal operation mode was activated via input "Normal
mode".
Economy Mode is activated with the input "Economy
mode".
A pump group fault is present.
The fan belt monitoring reports an error message.
The fault output in the energy recovery system reports an
error message. Check actuators of the energy recovery,
exchange if necessary.
The fire protection contact on the I/O-module of the control-
ler has triggered.
A controller reports that the humidifier of the adiabatic cool-
ing has no operating data or the fault input is activated.
The controller reports that the SWIRL-drive motor or its lim-
it switch has a malfunction.
This message is shown in the status line with an inversely
displayed "i". This operation information shows that the
controller that is displayed in the information is still initializ-
ing and not yet completly reactive. This message will dis-
appear once this controller has finished initializing. If
several controller are in use in one group, each one can be
displayed on the operation information list in case of a mal-
function.
The controller reports a fault of the ERS system with fan
stop.
The setpoint for the pressure or volume flow control will not
be reached, even with 100 % controller output.
