- The MEP2000 module can selectively turn off a single lighting point for an adjustable time duration ranging from 4 to 9 hours.
- The switching off is symmetrical with respect to the night centre, with a selectable offset of up to 2 hours (default setting is 1 hour).
- The module is preset to ensure that the light will stay on for a minimum of one hour in the morning.
MEP2000 turns off one or more lights automatically in the middle hours of the night time for an adjustable time period ranging from 4 to 9 hours. The lights-off time is distributed equally across the mid of the night time. Night middle line can be shifted forward by 0 to 2 hours.
Night duration is calculated based on the module's power-up period. The module saves the duration of the last 4 nights and calculates the average to estimate the duration of the current night. The module will not save durations under 5 hours. The module is factory set with 4 pre-set night durations of 15 hours.
NT = average duration of night time calculated as outlined above.
OT = off time set by the installer (from 4 to 9 hours; default setting 5 hours).
Offset = forward shift of night middle line. Can be configured by the installer (from 0 to 2 hours; default setting 1 hour).
ELT = evening lighting time: ELT = (NT-OT)/2+Offset
The module turns on the light after power-up for an ELT time, turns it off for an OT time and then turns it back on again as long as power stays on.
