Automatic channel switching
Only available in EXPERT mode
On two-channel time switches a cyclic switch between channels can be set to conserve and/or ensure even use of connected equipment such as lamps and
lights.
For example, with two sets of lights, one can be used all night long and the other for part of the night only. However, cyclical inversion of the outputs ensures
that the lamps are on for the same length of time on average. The outputs are automatically swapped over once a day (12 noon) or once a week (Sunday at
12 noon).
