• Reduced dimensions. Installation even inside the A.C. indoor unit.

• Quick and non-visible installation.

• External power not required.

• Direct connection to the KNX EIB bus.

• Direct connection to the AC indoor unit.

• Fully KNX interoperable, configuration from ETS.

• Multiple objects for control (of different types: bit, byte, characters…).

• Control of the AC unit based in the ambient temperature read by the own AC unit, or in the

ambient temperature read by any KNX thermostat.

• Total Control and Monitoring of the AC unit from KNX, including monitoring of AC unit’s state

of internal variables, running hours counter (for filter maintenance control), and error indication and error code.

2 Connection

Connection of the interface to the AC indoor unit:

Disconnect mains power from the AC unit. Open the front cover of the indoor unit in order to have access to the internal control board. In the control board locate the socket connector marked as ABG1.

Using a 3-wire cable, connect the ABG1 connector from the HA-AC-KNX-8/16/64 to the A B G1 connector of the AC unit's control board.

Fix the HA-AC-KNX-8/16/64 inside or outside the AC indoor unit depending on your needs – remember that HA-AC-KNX-8/16/64 must be also connected to the KNX bus. Close the AC indoor unit's front cover again.

Connection of the interface to the KNX bus:

Disconnect power of the KNX bus. Connect the interface to the KNX TP-1 (EIB) bus using the KNX standard connector (red/grey) of the interface, respect polarity. Reconnect power of the KNX bus.

Connections diagram:

Figure 2.1 Default parameter configuration

Each Haier Communication Adaptor connects to a single Outdoor Unit.

The HA-AC-KNX-8-16-64 can be connected to more than one Haier Communication Adaptor simultaneously.

NOTE: More than one Haier Communication Adaptor can be present in the installation. Please make sure that the address of the Haier Communication Adaptor is correctly set in the ETS. Check section 4.6 for more information.

4 ETS Parameters

When imported to the ETS software for the first time, the gateway shows the following default parameter configuration:

Figure 4.1 Default parameter configuration

With this configuration it’s possible to send On/Off (Control_ On/Off), change the AC Mode (Control_ Mode), the Fan Speed (Control_ Fan Speed) and also the Setpoint Temperature (Control_ Setpoint Temperature). The Status_ objects, for the mentioned Control_ objects, are also available to use if needed. Objects Status_ AC Ambient Reference Temperature and Status_ Error/Alarm are shown too.

The first field shows the URL where to download the database and the user manual for the product.

Figure 4.3 Parameter detail

4.1.2 Intesis Product

This parameter is used to check, before sending the programing, the maximum number of AC units your device supports.

Figure 4.4 Parameter detail

Select the version of the gateway that you have:

• HA-AC-KNX-8, if you only want to control up to 8 AC unit.

• HA-AC-KNX-16, if you only want to control up to 16 AC units.

• HA-AC-KNX-64, if you only want to control up to 64 AC units.

4.1.3 Number of Indoor Units in ETS

This parameter is used to hide/show communication object according to the number of AC units you need to configure. Value ranges go from 1 to 64.

Figure 4.5 Parameter detail

In case you introduce a number higher than the maximum number of units allowed by your license, you will get a warning message. This is just for information and will not block the configuration process. Configurations with more indoor units configured than the ones allowed by the license will not be downloaded correctly.

4.1.4 First Status Updated to KNX

This parameter defines how fast the status is updated to KNX. Depending on the value selected, more or less priority will be assigned to this action. As there are so many parameters available, it is important to consider carefully how to set this parameter.

o If set to “ASAP”, all status communication objects will send its value (if needed). o If set to “Slow”, all status communication objects will send its value (if needed), but slower

than in the previous option (ASAP).

o If set to “Super Slow”, all status communication objects will send its value (if needed), but

slower than in the previous option (Slow).

This parameter shows/hides the Control_ Ambient Temperature communication object which lets you use an ambient temperature reference provided by a KNX device.

19:

o If set to “no” the object will not be shown. o If set to “yes” the Control_ Ambient Temperature object will appear. Meant to be enabled

when you want the temperature provided by a KNX sensor to be the reference ambient temperature for the air conditioner. Then, the following formula applies for the calculation of real Control_ Setpoint Temperature sent ot the AC unit:

As an example, consider the following situation:

User wants: 19ºC (“KNX Setp. Temp.”) User sensor (a KNX sensor) reads: 21ºC (“KNX Amb Temp.”) Ambient temp. read by Haier system is: 24ºC (“Ambient Ref. Temp”)

In this example, the final setpoint temperature that HA-AC-KNX-8/16/64 will send out to the indoor unit (shown in “Setp. Temp.”) will become 24ºC – (21ºC - 19ºC) = 22ºC. This is the setpoint that will actually be requested to Haier unit.

This formula will be applied as soon as the Control_ Setpoint Temperature and Control_ Ambient Temperature objects are written at least once from the KNX installation. After that, they are kept always consistent.

Note that this formula will always drive the AC indoor unit demand in the right direction, regardless of the operation mode (Heat, Cool or Auto).

“AC Setp. Temp” = “Ambient ref. Temp” - (“KNX Amb. Temp.” - “KNX Setp Temp.”)

▪ AC Setp. Temp: AC indoor unit setpoint temperature ▪ Ambient Ref. Temp: AC indoor unit return temperature ▪ KNX Amb. Temp.: Ambient temperature provided from KNX ▪ KNX Setp. Temp: Setpoint temperature provided from KNX

Figure 4.24 Parameter detail

o If set to “Apply same initial state to all Indoor Units”, the parameter option selected

will apply to all indoor units.

o If set to “Initial state for each Indoor Unit might differ”, you will be able to set this

parameter for each Indoor Unit individually.
