Components The operating and display unit is made up of the following components: ● A high-quality aluminum front panel with an affixed sealed keypad and screwed-on printed circuit board. ● A plastic cover for surface-mounted units and for protection of the electronic circuitry (the cover can be omitted in certain cases of in-wall mounting). ● "Green Leaf" energy efficiency function. ● Three ring indicating lights (5 LEDs each).
Engineering 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.
Operation The fume hood operating display unit is optically and functionally divided into the three following sections: ● Monitoring and alarms ● Local operation ● Universal functions Monitoring and alarms The functions described are examples and application dependent. The monitoring and alarms section comprises of three LED rings, 1 alarm buzzer and 1 button with its own LED. The Alarm LED ring is divided into 2 groups. The Warning and Safe mode LED rings have one group each.
Universal Functions The universal functions section comprises of three buttons. The button with the hand symbol allows switching between manual override or normal operation of the schedule. The LED next to the button with the leaf symbol indicates efficient operation when the leaf is green and turns red when operation is not optimal. The button will return the fume hood to energy efficient operation. The button with the light bulb turns the fume hood light on or off. Connecting KNX R1 QMX3.
