Samson TROVIS 5500 - Temperature Monitoring; Error Status Register

Operational faults
− Outdoor sensor AF1: When the outdoor sensor fails, the controller uses a ow tempera-
ture set point of 50°C or the 'Max. ow temperature' when the max. ow temperature
(PA1, 2 > P07) is lower than 50°C.
− Flow sensor(s) in heating circuit(s): When the ow sensors in the heating circuits are de-
fective, the associated valve moves to 30% travel. DHW heating using such a sensor to
measure the charging temperature is suspended.
− Flow sensors in the DHW circuit with control valve: When the ow sensor VF4 fails, the
controller behaves as if VF4 has not been congured. As soon as the control of the
charging temperature becomes impossible (VF2 defective), the associated valve is closed.
− Return ow sensors RüF1/2: When the return ow sensor fails, the controller continues
operation without return ow temperature limitation.
− Room sensors RF1/2: When the room sensor fails, the controller uses the settings for op-
eration without room sensor. The controller, for example, switches from optimizing mode
to reduced operation. The adaptation mode is canceled. The last determined heating
characteristic remains unchanged.
− Storage tank sensors SF1/2: When one of the two sensors fails, the storage tank is no
longer charged (exception: solar system).
− Solar circuit sensors SF3, VF3: When one of the two sensors fails, the storage tank in the
solar circuit is no longer charged.
9.3 Temperature monitoring
When a system deviation greater than 10°C persists in a control circuit for 30 minutes, an
"Err 6" message (temperature monitoring alarm) is generated.

9.4 Error status register
The error status register is used to indicate controller or system errors. In modem operation
when the controller dials the building control system (GLT) both when an error is detected
and when it has been corrected (CO6 > F06 - 1), each change in the status of the error sta-
tus register causes the controller to dial the control system. The error messages causing a
change in state of the error status register highlighted in the following table (bold).
