Operational faults
7.2 Sensor failure
According to the error list, sensor failures are indicated by displaying “Err 1“ error
message in the error level. For detailed information, exit error level and view the
differ- ent temperature values in the information level: each sensor icon
displayed together with 3 horizontal lines instead of the measured value indicates
a defective sensor. The following list explains how the controller responds to the
failure of the different sensors.

Outdoor sensor AF : When the outdoor sensor fails, the controller uses a flow
tem- perature set point of 50 °C or the Max. flow temperature when the Max.
flow tempe- rature (adjusted at PA1) is lower than 50 °C.

Flow sensor in heating circuit : When the flow sensors in the heating circuits
are defective, the associated valve moves to 30 % travel.

Return flow sensors RüF : When the return flow sensor fails, the controller continu-
es operation without return flow temperature limitation.

Room sensors RF : When the room sensor fails, the controller uses the
settings foroperation without room sensor. The controller, for example, switches
from optimi-
zing mode to reduced operation; adaptation mode is canceled. The last
determined heating characteristic remains unchanged.
7.3 Temperature monitoring
When a system deviation greater than 10 °C persists in a control circuit for 30
minutes, an “Err 6“ error message (temperature monitoring alarm) is generated.

7.4 Error status register
The error status register is used to indicate controller or system errors. In modem
opera- tion mode when the controller dials the building control system (GLT) both
when an er- ror is detected and when it has been corrected, each change in
the status of the error status register causes the controller to dial the control
system. You can define which er- ror messages are to influence the error status
register after entering the key number 0025. The default setting of 465 results in just
the error messages highlighted in the ta- ble (bold) causing a change in state of
the error status register.
