5.2.3.1.Connection (switch functions)
The menu item "connection" appears only for the settings for the switch function
channel if selected "Use switch functions: Yes".
In the connection object ("Channel X connection") different communication objects can
be linked with AND or OR. E.g. a light can only be switched on if the button input is
active AND twilight is active.
5.2.3.2.On/Off switch delays, time switching (switch functions)
The menu item appears only for the settings for the switch function channel if a time
function is chosen. The menu item has the same name as the selected function.
With the switch on and off delay, a switch can be used for example for a HVAC unit and
light. Through the switch on delay the ventilator will only start if the light has already
been turned on for a few minutes. The switch off delay effects that the ventilator will
follow up if the button was operated again and the light is already off.
The staircase timer function makes sure for example that the light is on for a defined
period of time and then turns off automatically.
Switch on delay
The switch on delay is set with a time basis and time factor (e.g. 1 min × 4 corresponds
to 4 minutes). Additionally it is specified if the time interval for a repeat receipt of a
switch-on telegram is extended ('triggered again", e.g. by pressing the button again)
and what happens when a switch off telegram arrives from the bus.
Switch off delay
The switch off delay is set with a time basis and time factor (e.g. 1 min × 4 corresponds
to 4 minutes). Additionally it is specified if the time interval for a repeat receipt of a
switch-off telegram is extended ("can be triggered again", e.g. by pressing the button
again) and what happens when a switch off telegram arrives from the bus.
