Start-up mode
When the mains supply is initially connected to the PIR occupancy switch
it goes through its Start-up Mode. This means it switches on for about
1 minute, then switches off and enters its Operating Mode. If a manual wall switch is feeding the PIR occupancy switch (see wiring diagrams on appropriate product pages) then it will go through the Start-up Mode each time the wall switch is switched on. By wiring the manual wall switch in the alternative position, the supply to the PIR occupancy switch is uninterrupted and it remains in Operating Mode. It does not go through its Start-up Mode each time the wall switch is switched on.
