1 GENERAL DESCRIPTION
The BUSing-MDAC-D gateway allows direct communication from a BUSing® protocol installation with
compatible Midea® climate units. This makes it easy to control the machine from BUSing screens, web servers
or the Ingenium app available for mobile devices (iOS and Android) with a fully graphical and visual interface.
Apart from reading ambient temperature, set point temperature may be consulted and modified, as well as
indicating to the machine its mode of operation and fan speed.
Each gateway will allow the control of an internal Midea® climate unit, to which it is connected directly through
a connector supplied with the gateway, to the internal unit S21 connection. The maximum cable distance
between machine and gateway must be 1 m.
To ensure compatibility of the gateways, contact the technical service or consult the compatibility table.

2 TECHNICAL DESCRIPTION
• Gateway for integration of Midea AC air conditioning system and BUSing® protocol.
• Allows control of one indoor Midea unit (check compatibility table)
• Direct communication through 2 wires with no polarity, to HA and HB terminals from indoor unit.
• Control and monitoring of the status and operating modes of the Midea climate machine.
o On/Off machine
o Ambient temperature
o Consignment temperature
o Modes of operation
o Machine speed
• Mounting next to the climate unit or integrated into the ceiling.
• Does not support master/slave due to it works either with Midea remote control connected or not,
being the last order received priority.
• It allows control from BUSing® screens, web servers or the free Ingenium App.

3 PROGRAMMING OF THE DEVICE
From the Development System (SIDE) BUSing-AC node must be inserted in the integrations tab, in the address
wanted the gateway to have.
By double-clicking or right-clicking on the icon, and accessing its properties, a window will open like the
following:
The only thing that needs to be programmed in this part, is to name the machine 1, which will be the one
appearing, when linking it, on the graphical interfaces. The rest of the machines will not be used, as this
gateway can only control one climate unit.
Once entered in the BUSing project and having only connected to the BUS this computer, the device should
be addressed, right click on it and select Program this node by appearing the property screen on which you
must click on programming. You can also right-click: Direct and program node.

3.1 POINT TO POINT CONTROL IN PPL
To be able to control the machine it will be necessary to include a thermostat icon on one of the graphical
interfaces or web server of BUSing®, and make a point-to-point link. The following example is about Ethbus3
or PPL.
In the Web Server Planes tab, with a previously added plane, through the red icon, located on the right side:
Click on a thermometer icon, available in the icon battery on the right. Next, with the mouse you click on the
part of the plane you want to incorporate this icon:
And the map would look like:

PROGRAMMING MANUAL
BUSING-MDAC-DV1.0
Gateway

The next step will be to make a point-to-point link of the thermostat icon with the AC gateway. To do this, you
must right click on the icon and select the option Link control point-to-point.
When clicking on this option, a window will appear like the next one, with all the nodes added to our project
(in Installation Modules). Select the corresponding node for AC gateway, in the case of the example, node 4
and press Ok.
Again, a window will appear to select the Midea machine to add. It is reminded that this gateway only controls
1 indoor climate unit, so only the first machine should be selected, though 0 to 63 machines are available. This
is because that BUSing-AC icon added in Installation Modules serves to program other BUSing AC gateways
that can control more than one AC unit.

Once pressed Ok, the point-to-point control of the gateway would already be linked with its corresponding
icon on the PPL. For further information regarding programming a PPL, check its programming manual.
Once downloaded the programming to the screen or webserver, the graphic interface for this device would
look like the following:
On the left side, the ambient temperature can be read, the next value in the rectangle is the setpoint
temperature. Finally, at the left bottom are the available modes of the AC unit, and on the right side the speed.

The only information to be turned to the gateway is the BUSing address. If you click on the icon to
reprogramme this node, no window will appear to confirm the programming, since the name assigned to
machine 1 in the gateway properties is necessary for point-to-point control linking on a screen/web server.
