The 24-hour time switch has a 24-hour switching dial. It carries 96 tappets, which
means four tappets per hour, giving a resolution of 15 minutes. The shortest possible
heating period also is 15 minutes.

The weekly time switch has a 7-day switching dial. It carries 84 pairs of tappets, which
means 12 pairs of tappets or 24 individual tappets per day.
The resolution is thus one hour. However, since – for mechanical reasons – at least two
tappets need to be tilted together to set one heating period, the shortest possible heat-
ing period is two hours.
