etc.
The control unit can also be used to display the current
parameters for volume flow, pressure and temperature.
Additionally, further faults are also indicated here.
For reading the control unit or operating hours counter first the
electrical control box must be opened. The current parameters
and faults are indicated on the display (21).

to tripping of the safety temperature limiter. Actuate the
reset switch (20) of the safety temperature limiter and
restart the device.
