time switch Grässlin SU/1 digi 20

Digital timer for precise weekly programmes.

This 1-channel weekly timer for mounting on a DIN rail is designed for professional use in building services and electrical engineering. With up to 50 individually programmable switching times, you can control heating or lighting systems precisely and reliably. The switching status indicator and the illuminated display allow you to control the system reliably even in poor lighting conditions. The automatic changeover between summer and winter time saves you manual rework - ideal for permanently operated systems. The integrated operating hours counter simplifies control of maintenance cycles, while the manual switch allows flexible reactions in everyday life. Even in the event of a power failure, all settings are retained in the EEPROM, which ensures maximum operational reliability.

More control, less effort - for a relaxed working day.
