Sensor failure

According to the error list, sensor failures are indicated by displaying "Err 1" message in the
error level. For detailed information, exit error level and view the different temperature val-
ues in the operating 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 con-
troller responds to the failure of the different sensors.
4
Outdoor sensors AF1/2: 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 tempera-
ture (adjusted under PA1, 2, 3) is smaller than 50 °C.
4
Flow sensor(s) in heating circuit(s): When the flow 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.
4
Flow sensors in the DHW circuit with control valve: When the flow sensor VF4 fails, the
controller behaves as if VF4 had not been configured. As soon as the control of the
charging temperature becomes impossible (VF2 defective), the associated valve is closed.
4
Return flow sensors RüF1/2/3: When the return flow sensor fails, the controller contin-
ues operation without return flow temperature limitation.
4
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; adaptation mode is canceled. The last determined heating charac-
teristic remains unchanged.
4
Storage tank sensors SF1/2: When one of the two sensors fails, the storage tank is no
longer charged (exception: solar system).
4
Solar sensors SF3, VF3: When one of the two sensors fails, the storage tank in the solar
circuit is no longer charged.

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.

Collective error message

With the setting CO5 -> F07 - 1, the binary output BA13 is set when an operational fault oc-
curs, which causes a change in state of error status register. The setting bA = 1 causes the
binary output BA13 to close when a fault occurs.
