Allow a minimum of 1 second to elapse after the lights have gone off before
repressing the momentary switch (allowing CESRA PIR to reset).

Troubleshooting
The load will not switch on when the momentary switch is operated:
• TheLUXadjusterissettoolowandisinhibitingtheswitch.
The Absence detector switches off when the room is occupied:
• Theoccupationisoutsideofthedetectionzone(seediagramA),
movementsaretoosmallortooinfrequent.IncreasetheTIMEadjuster.
