5.4 E xternal interface
1 8 B
The external interface is activated on the Settings parameter page.
It consists of the 3 inputs E1, E2 and E3.
E1 and E2 are purely binary inputs, E3 can be used both as a binary input and as an
analogue input for an external temperature sensor.
All 3 inputs are connected in the base via the connection terminals
The following functions can be realised:
• Switching (1 switch or button)
• Blind up/down (with 2 buttons on E1 + E2)
• One-panel blind operation (with 1 button)
• Dimming brighter/darker (with 2 buttons on E1 + E2)
• One-panel dimming operation (with 1 button)
If the blind and dimming functions are implemented via 2 buttons, E1 and E2 are
automatically connected with one another and act jointly on objects 9, 10 and 12.
