“Look Mum, no hands!”

The striking thing about the plantroom panel switches above is that V-SWITCHHANDthey lack the ‘HAND’ position that is normally provided to allow equipment to run manually, and which are all too frequently found in that condition (right).

If you genuinely need to be able to let people in the plantroom override the automatic control, then at least get your building management system to monitor the switch position to alert you. Otherwise you just end up with stuff running continuously that doesn’t need to.
