A week program comprises an ON/OFF ime and assigned ON/OFF days. Year programs: Programs ha are only o be execued wihin a defined period of validiy. They overlap wih he week programs of he same channel according o an OR operaion. The period of validiy is specified by enering he sar/end dae. Validiy from sar dae 00:00:00 o end dae 24:00:00. The sar dae mus be prior o he end dae. Wihin heir period of validiy, hese programs ac as week programs. Ouside heir period of validiy, hese programs have no influence on he swiching behavior. Excepion programs: Have a higher prioriy as week and year programs. Week and year programs of he same channel will no be execued wihin he period of validiy of an excepion program, however, wihin he period of validiy oher excepion programs will be execued. The differen excepion programs overlap according o an OR operaion. Cycle funcion: On he year ime swich, channel 1 has an addiional opion for "cyclic swiching". The erm "cyclic swiching" means ha wihin a specific period, he ime swich is swiched on for a specific duraion (ON ime). The cycle ime can be beween 2 seconds and 2 hours.

The 7LF6 113 sairwell lighing imer, he 7LF6 114 lighing imer and he 7LF6 115 energy-saving imer warn of an impending off by flashing, he 5TT1 303 sairwell lighing imer ECG warns of he impending swich-off by dimming, allowing sufficien ime for he ligh swich o be pressed again. Manual swiches All imers have a manual swich for he funcion Auomaic/ON. This allows he operaor o swich o coninuous ligh in he even of moving house or emergencies. Useful coninuous conac Pushbuons should never jam. For his reason, all our imers have a safeguard o preven his ype of malfuncion. Even beer, his feaure can be used (e.g. by careakers of properies) o swich o a coninuous ligh in he even of moving house or emergencies. Seing accuracy The elecronic remoe conrol swiches offer a high degree of accuracy. The runime can be se precisely o + 30 seconds using he push-o-lock knurling wheel seing. The facory seings ensure ha he limi values of 1 and 10 or 60 minues can be reliably se. Shor-circui srengh Sairwell lighing imers are primarily used for he swiching of incandescen lamps, which may occasionally be subjec o shor circuis. A key feaure of all devices is heir high shor-circui srengh wihou he conacs welding. Swiching of fluorescen lamps In order o exend heir service life as far as possible, fluorescen lamps should only be swiched using a sairwell lighing imer if he swiching frequency is no excessive. Using elecronic ballas (ECG) o operae hem is more genle on he device and saves energy. The 5TT1 303 sairwell lighing imer ECG swiches he elecronic ballas and warns of he impending swich-off by dimming. Swiching of energy-saving lamps The swiching of energy-saving lamps has provoked heaed discussions. Energy-saving lamps require a cerain ime before hey produce heir full ligh oupu. The characerisic of he elecronics is no ideal for flashing operaion. They do no dim.
