Binary Input
With binary inputs we basically distinguish between battery-supplied and mains-supplied devices.
Both types of devices can control any actuator (switching actuator, dimming actuator, shutter
actuator), but they can also send information to the Home Manager (open contact, closed contact,
e.g. in case of a call-in for a window status).
Mains-supplied binary input:
As its name implies, this type of binary input is 230VAC driven.
It provides two potential-carrying inputs (channel A, channel B) where the voltage applied can be
measured (see Instructions for Installation) and from where different commands can be sent,
depending on the value and configuration (mode) of the binary input.
Battery-supplied binary input:
This type of binary input is battery-driven (3V via CR2477N).
Potential-free contacts can be connected to the inputs (channel A, channel B). The binary input
evaluates the status (closed, open) and the device in a different way, depending on the
configuration (mode), and reacts by sending different commands.
The following description of the modes is applicable both to mains-supplied and battery-supplied
binary inputs.
Mode 1:
In this mode both inputs (A and B) are treated as push-buttons and we distinguish between a short
