Why does my Weather protected Sunset Switch not turn on when power is first applied?


21 September 2022

Unlike other sensors during the ‘warm up’ period when power is applied for the first time, or re-applied after a power failure, the Sunset Switch will remain idle for this short period. The load will not be turned on during this period even if the ambient light level is below the switching threshold.
Two Wire designs typically have 3.5 minutes (approx) and Three Wire Designs typically have 90 seconds (approx) for the Warm-up time.
