WARNING
Danger to life due to the electrical voltage at the Multi-IO Box!
• Only an authorised electrician may open the device.
• Always disconnect from the mains network and secure against unintended activation before open-
ing.
• Disconnect external voltages and secure against activation.
The wiring of the MIOB depends on several factors and must be planned and carried through carefully
by the installer.
The following cross-sections are applicable for plug-in/clamping connections:
• solid wire: 0.75 – 2.5 mm²
• stranded wire (with and without end sleeves): 0.75 – 2.5 mm²
• 8 - 9 mm insulation stripped off the wire
6.1 Supply connection
6.2 Boiler connection (4.1/4.2)
The terminal 4.1/4.2 is a relay as potential-free switch. For the standalone variant, only the boiler is
connected. If the Alpha IP Access Point is operated using the Alpha IP app, the terminal can also be
used for air dehumidifiers or for the Change Over Pilot (CO Pilot). Alternatively, with Homematic CCU 2
it is possible to use the terminal as a switch actuator.
