6.3 Temperature monitoring
If the collector temperature deviates more than 50 K from the turn-on threshold with
running collector pump for a period of 30 minutes, the error message "Err 6" is generated
(temperature monitoring alarm).
It is assumed that the heat carrier medium does not circulate any more. Possible
reasons may be:
Air in the system
Defective pump or pump is stuck

6.4 Error status register
The error status register is used to report controller or system failures. In modem
operating mode with error reporting function, each change of error status (error
detection/error correction) triggers a dial up connection to the building master control
system/station (BCS) to report the status change. The errors that should affect the error
status register can be set after having entered the access code 0025.
The default factory setting „465“ causes that only the error messages in bold in the
following table affect the error status register.
