zNote
To set the ON and OFF delay times, the user level (C79) should be set to “advanced
configuration.”
The ON and OFF delay times are set to 0.0 s when the product is shipped.

is shipped. With this setting, a timer can be started or stopped for all internal events by a
single internal contact (DI).
If the setting is changed to 1 or more, a timer can be started or stopped for one specified
internal event by one internal contact (DI).
To change the setting, the user level (C79) should be set to “advanced configuration.”
