1.2 Behavior of the system to a power failure
 The system configuration is non volatile and is permanently
retained. It consists of the following settings:
– Sensor settings
– Settings and links of the relay outputs
– Modbus settings
– System settings (display language, air pressure/altitude,
passwords etc.)
 Linked relay outputs switch to the non active condition (open).
 A restart is carried out automatically when the power returns. The
system continues to work with the settings at the time of the power
failure (except for the time).
