Each time switch has four channels which you can use to set four on and off
times. The channels are set via the parameter display.
The timer has a back-up battery. This means that it will continue to run in the
event of a power failure, although the time switch relays will not switch. The
contacts are kept open when de-energized. Information on the battery back-
up time are provided on (￫ Chapter 8 "Appendix", page 211).
