4.5 Functions
Split Units are devices from the heating, air-conditioning and ventilation sector that are generally
operated with an infrared remote control.
The Split Unit Gateway is installed in close proximity (maximum distance of 2 metres) of the
Split Unit and the transmission unit of the enclosed cable is glued directly on the receiving unit
of the Split Unit.
This allows the Split Unit to be activated. The Split Unit Gateway makes it possible for the user
to integrate the Split Unit into an existing free@home system and to control the system
comfortably and energy-efficiently.
Available functions
Switching on/off
■
Switches the Split Unit on or off.
Specifying the set-point temperature including parameterizable set-point temperature limit
■
The setpoint is sent to the Split Unit.
■
The control is then carried out by the Split Unit.
Setting the operating mode (Automatic, Heating, Cooling, Ventilation, Drying)
■
These are the standard operating modes of most Split Units.
Control of fan speed level
■
The fan speed level can be controlled.
■
There are 3 fan speed levels (1, 2, 3) and the fan speed level can also be controlled
automatically.
■
The Split Unit then adjusts the fan speed level itself.
Slat adjustment horizontal and vertical
■
The movement of the slats can be activated/deactivated for many Split Units.
■
The slats adjust the direction of flow.
Activation of silent mode
■
Many of the latest Split Units support this function.
■
If this function is activated, the outdoor unit of the Split Unit runs with reduced power, which
reduces the creation of noise, e.g. at night.
Notice
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 back from it.
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.
