Introduction

The Split Unit Gateway forms the interface between the ABB-free@home
conditioning devices, so-called split units, from a wide range of manufacturers. The device
converts the ABB-free@home
Split Unit.
The Split Unit Gateway is installed in close proximity (maximum distance of 2 metres) to the
Split Unit. The transmission unit of the enclosed cable is glued directly on the receiving unit of
the Split Unit. The air-conditioning device then no longer receives commands from a remote
control, but can be operated via any ABB-free@home
The following functions are provided:
Switch-on / switch-off

Not all Split Units support all functions. Only functions that the respective
Split Unit supports are enabled in the user interface.
Example: Some Split Units do not support all operating modes.
The Split Unit Gateway supports 3 fan speed levels and automatic. To the
extent a Split Unit supports fan speed levels, they are mapped accordingly.
Example: A Split Unit has 5 fan speed levels. Then levels 1/3/5 are mapped
to 1/2/3 and levels 2+4 cannot be activated.
The communication to the Split Unit is unidirectional. This means that while
the Split Unit Gateway sends commands to the Split Unit, it does not receive
a status message from it. Therefore, if a Split Unit is operated in parallel with
a remote control, the status of the gateway can deviate from the actual
status of the Split Unit. The same applies when a Split Unit is not ready to
receive. Then, if necessary, a command may have to be sent via ABB-
free@home ® so that the status values are again being synchronized.
