7-day time switch EZ500 and EZ700 with type suffix EZ…-..-.C. are provided
with a real-time clock. The time switches can only be used
effectively in these devices.
EZ offers eight 7-day time switches
Ö1 to Ö8 for up to 32
switch times.
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. When the timer is
disconnected from the power supply, the contacts remain
open. Information on the battery back-up time are provided on
page 260.
A 7-day time switch can be integrated into your circuit in the
form of a contact.

The procedure for setting the time is described under
section “Setting date, time and daylight saving time” on
page 209.
