Question
E.g., fault status message
"[HC 1] error flow sensor" ap-
pears although a sensor is
connected.
When commissioning the plant,
the wrong language was se-
lected.
How do I find the language I
need?
The device is completely
switched off, "Operation locked,
Remote operation" appears.
How do I start the device again?
The buttons on the QAW740
room unit do not work.

Check to see if, in addition, fault "Fault extension
module" occurred. This fault can lead to the
display of subsequential faults.
1. Press the ESC button and the OK knob simul-
taneously.
2. Choose the password level and enter number
112 as the password (same as international
emergency call) and confirm by pressing the
OK knob. The language changes to English.
3. Select your language from the Settings > Device
> Language menu.
Remote operation (OCI700.1) set the device to
commissioning mode, which has locked local
operation.
If the device is not corrected restarted via remote
operation, it maintains this state. Locally, the
device can only be restarted by briefly discon-
necting the power supply.
The room operating mode on the controller is
overridden by a higher priority.
