Modular lighting timers (up to 3600 W for incandescent light and halogen light). A contact closes and opens after the set time interval, which can be set in the range from 30 seconds to 20 minutes; adjustment is made using a potentiometer. Automatic mode: lighting timer is restarted when a new action is performed. Override: permanently switched on. Warning before the lighting is switched off by the light source flashing at the end of the time delay. Two automatic operating modes (timer with or without pre-warning) and override. Two command sequences can be received by push-button: Pulse control for 2 seconds: Starts the customisable time delay. During this period, a further pulse of 2 seconds starts the time delay (MINp) or the lighting is switched off (MINt). Pulse control for more than 2 seconds: Starts the fixed time delay for 1 hour. During this period, a further pulse of 2 seconds restarts the time delay for 1 hour, and a further pulse of more than 2 seconds switches the lighting off.
