Overriding operating mode defaults set
by the central BMS
Operating mode default settings from the central
BMS or from the room control panel can be
overridden on the control panel for the fume
cupboard controller.
Temporary override
A centrally set operating mode can be temporarily
overridden at any time using the operating mode
button on the control panel. The operating mode
selected on the control panel remains active until
the central BMS sets another operating mode. If the
central BMS sets a different default operating
mode, it overrides the locally activated operating
mode.
Manual control for permanent override
A centrally set operating mode can be
permanently overridden on the control
panel. To do so, first activate manual
control by pressing the corresponding
button to prevent further overrides from
the central BMS. Then set any other operating
mode on the control panel.
This operating mode default setting can be
terminated by pressing the manual control button
again. The fume cupboard controller then resumes
the previous operating mode from the central BMS.
Manual operation can be set for a limited period of
time. The manual mode will then automatically be
deactivated after the set delay and the previous
operating mode will be resumed.
No override option
The central BMS can suppress overrides from the
control panel temporarily or permanently. In this
case, manual control cannot be used, and the
control panel shows only the centrally set operating
mode. If a user attempts to change the operating
mode on the control panel, the active operating
mode will blink briefly.
