Outdoor sensors AF1: When the outdoor sensor fails, the controller adjusts a flow tem
-
perature set point of 50 °C or the
Max. flow temperature
when the
Max. flow tempera
-
ture
(adjusted under PA1, 2) is smaller than 50 °C.
4
Flow sensor(s) heating circuit(s): When the flow sensors in the heating circuits are defec
-
tive, 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: When the return flow sensor fails, the controller continues
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 sensors SF1/2: When one of the two sensors fails, the storage tank is no longer
charged (exception: solar system).
4
Solar sensors SF 3, VF 3: When one of the two sensors fails, the storage tank in the solar
circuit is no longer charged.
8.3 Temperature monitoring
When a system deviation greater than 10 °C persists in a control circuit for 30 minutes, an
error alarm “Err 6“ (temperature monitoring alarm) is generated.
