System 3000
Relay switching insert 2-gang
5 Operation with 1-gang push-button top
Switch load
With the 1-gang push-button top, output a2 switches depending on the switching state of output
a1.
￭ Press push-button.
Output a1 and a2 switch on and off.
Extension unit operation
Operation using 2-wire extension, push-button or rotary dimmer extension corresponds to oper-
ation on the main device.
Operation via 3-wire extension with 1-gang push-button top: Press top to switch on, press bot-
tom to switch off.
Activate switch-on delay of output a2
For output a2, a switch-on delay of 3 minutes can be switched on. It starts as soon as output a1
is switched on. If output a1 is switched off again before the switch-on delay has expired, output
a2 remains switched off.
Requirements: Both outputs are switched off.
￭ Press the button cover over entire surface for longer than 4 seconds.
Both outputs are switched on immediately. After 4 seconds, output a2 is switched off.
￭ Release the push-button top.
The switch-on delay is switched on.
Deactivate switch-on delay for output a2
Requirements: Both outputs are switched off.
￭ Press the button cover over entire surface for longer than 4 seconds.
Output a1 is switched on immediately. After 4 seconds, output a2 is also switched on.
￭ Release the push-button top.
The switch-on delay is deactivated. Both outputs are switched on simultaneously.
Run-on time
For output a2 a run-on time can be set (see Setting the time function/run-on time). It starts as
soon as output a1 is switched off.
If output a1 is switched on before output a2 is switched off, the run-on time of output a2 is only
restarted if:
– output a1 is switched off when the switch-off delay for output a2 is switched off.
– output a1 is switched off after more than 3 minutes when the switch-on delay for output a2
is switched on.
6 Operation with motion detector as standard or timer with display
In combination with a motion detector as standard or a timer with display, the switch insert be-
haves as with a 1-gang push-button top. The motion detector switches on output a1 and
switches it off again after the run-on time of 2 minutes set in the motion detector has expired.
The timer switches output a1 on or off manually or automatically. Output a2 switches immedi-
ately or with a time delay, depending on output a1.
Switch-on delay
The switch-on delay for output a2 is switched on or off at the insert.
– For this, a 1-gang push-button top is placed on the insert instead of a motion detector and
is then replaced by the motion detector after the switch-on delay has been set.
