Fume hood automation
The slim design of the operator display unit enables it to be mounted in a laboratory fume hood
post or in a door frame.
The unit complies with the requirements for a fume hood operating device (see Conformity).
Volume flow control, monitoring and light control can be implemented and automated for a fume
hood together with a fume hood controller.
Flexible use
The functionality of the buttons, LEDs and alarm buzzer is defined by the application in the
controller that controls the operator display unit. This ensures that the unit can be flexibly used.
Mounting
The operating and display unit is used for fume hood and room automation. It can be mounted
on a surface or in the wall. The back cover can be removed and is not needed in the case of in-
wall mounting.
Mounting options
See the QMX3.P88-1WSC installation instruction (A6V10859253) for detailed information.
