Error Code - Bosch CS 3000 AWP Installations- Und Bedienungsanleitung

When the master unit is in protection, only the master unit stops and the
other units carry on working.
When a slave unit is in protection, this unit stops and the other units are
not involved.
If the master unit fails, the slave units also stop working.
Temperature sensors
All temperature sensors are classed as faulty when the voltage on the
corresponding input is lower than 0.05 V or higher than 4.95 V.
After an error has been signalled, all units stop. The error is eliminated
after the sensor has been restored.
