LEDs flash, 
Fault LED = On
|
| Internal error in RLS room air control Fault rectification: Ensure that no voltage is present, restart the control. To perform a reset of the control, press Press |
|
| Overtemperature/overload of mains adapter Fault rectification: Check the ambient temperature and allow the mains adapter to cool down. |
|
| No communication or failure of the external power units/RLS or ventilation units (PPB 30 K, RV 2, CPP 60) Fault rectification: Check the connection to the LT power unit/RLS room air controls and PPB 30 K, RV 2 or CPP 60 ventilation units. Check the settings in the software (e.g. activated LTs and ventilation units that are not connected). Incorrect addressing (e.g. two slaves with the same address). |
|
| No communication and/or failure of the sensors (RS 485, I2C) Fault rectification: Check connection to the sensors. Check settings in the software (activated sensors that are not connected). |
|
| Internal system error – RLS slave power unit / ventilation unit Fault rectification: Switch off the voltage. |
|
| No communication with the EnOcean module (PP 45 EO) Fault rectification: Check wiring. If the connection is correct, the error disappears. |
|
| No communication with taught-in sensor Fault rectification: Check cable connection to taught-in sensor. |
