1 Presentation

INKNXHAI0–C000allows a complete and natural integration of Haier air conditioners with KNX control systems.Compatible with all models of VRF line of Haier air conditioners.

Main features: 

• 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.
• AC unit can be controlled simultaneously by the IR remote control of the AC unit and by KNX.

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 INKNXHAI0- C000to the A B G1 connector of the AC unit’s control board.

Fix the INKNXHAI0–C000inside or outside the AC indoor unit depending on your needs – remember that INKNXHAI0–C000must 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:

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.

                           Figure 4.2 Default communication objects

4.1 General configuration

Inside this parameter’s dialog it is possible to activate or change the parameters shown in the Figure 4.1.

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.Figure 4.6 Parameter detail

4.1.4 First Status Updated to KNXThis 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.

4.3 Global Fan Speed Configuration dialog

Figure 4.13 Default Fan Speed Configuration dialog

All the parameters in this section are related with the Fan Speed properties and communication objects.

4.3.1 DPT object type for fan speed

With this parameter is possible to change de DPT for the Control_ Fan Speed and Status_ Fan Speed byte-type communication objects. Datapoints Scaling (DPT_5.001) and Enumerated (DPT_5.010) can be selected.

• When “Enumerated [DPT 5.010]” is selected, Control_ Fan Speed and Status_ Fan Speed communication objects for this DPT will appear. Also, depending on the number of fan speeds selected, these objects will be different.The first fan speed will be selected if a “1” is sent to the Control_ object. The secondone will be selected sending a “2”, and the last one sending a “3”.The Status_ object will always return the value for the fan speed selected. Important: If a “0” value is sent to the Control_ object, the minimum fan speed will be selected. If a value bigger than “3” is sent to the Control_ object, then the maximum fan speed will be selected.
• When “Scaling [DPT 5.001]” is selected, Control_ Fan Speed and Status_Fan Speed communication objects for this DPT will appear. Also, depending on the number of fan speeds selected, these objects will be different.

When a value between 0% and 49% is sent to the Control_ object the first fan speed will be selected.When a value between 50% and 83% is sent to the Control_ object, the second speed will be selected.When a value between 84% and 100% is sent to the Control_ object, the third speed will be selected.The Status_ object will return a 33% when the first speed is selected, a 67% for the second one and a 100% for the third one.

4.4 Global temperature configuration

Figure 4.20 Default Temperature Configuration dialog

All the parameters in this section are related with the Temperature properties and communication objects.

4.4.1 Enable use of +/- obj for Setpoint

This parameter shows/hides the Control_ Setpoint Temp +/- communication object which lets you change the indoor unit setpoint temperature by using two different datapoint types.

• If set to “no” the object will not be shown.
• If set to “yes” the Control_ Setpoint Temp +/- object and a new parameter will appear.

                                    Figure 4.23 Parameter detail

➢ DPT type for +/- Setp Temp objectThis parameter lets choose between the datapoints 0-Up / 1-Down [DPT_1.008] and 0-Decrease / 1-Increase [DPT_1.007] for the Control_ Setpoint Temp +/- object.(Lower limit) 16ºC 17ºC … 31ºC 32ºC (Upper limit) Up / Increase Down / Decrease

4.4.2 Ambient Ref. Temp. is provided from KNX

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

• If set to “no” the object will not be shown.
• 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:“AC Setp. Temp” = “Ambient ref. Temp” – (“KNX Amb. Temp.” – “KNX Setp Temp.”) 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 KNXAs 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 INKNXHAI0–C000will 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).

• If set to “no” the objects will not be shown.
• If set to “yes” the Control_ and Status_ Control Mode objects for No Central, LIFO (Last Input First Output), Central Controller, Lock Central Controller will appear.

• If set to “Apply same initial state to all Indoor Units”, the parameter option selected will apply to all indoor units.
• If set to “Initial state for each Indoor Unit might differ”, you will be able to set this parameter for each Indoor Unit individually.
