Operational faults

Malfunctions or faults are indicated by the blinking
"Err" alarm is displayed immediately. Press the rotary pushbutton to open error level. It may
be possible to view several alarms by turning the rotary pushbutton. As long as an error
alarm is present, error level is displayed, even though it has not been opened by pressing the
rotary pushbutton.
In error level, the error alarm is displayed as specified in the list below.

Sensor failure

According to the error list, sensor failures are indicated by displaying "Err 1" in error level.
For detailed information, exit error level and view the different temperature values in info

interrupted) instead of the measured value indicates a defective sensor. The following list ex-
plains how the controller responds to the failure of the different sensors.
4
Outdoor sensor AS: When the outdoor sensor fails, the controller adjusts a flow tempera-
ture set point of 50 °C or the Max. flow temperature when the Max. flow temperature
(adjusted under PA1) is smaller than 50 °C.
4
Flow sensor VS1: When the flow sensor in the heating circuit fails, the associated valve
moves to 30 % travel. DHW heating using such a sensor to measure the charging temper-
ature is suspended.
