1. Presentation

DK-RC-KNX-1i allows a complete and natural integration of DAIKIN air
conditioners with KNX control systems.

Compatible with all SKY Air and VRV models commercialized by DAIKIN.

Main features:

 Reduced dimensions, quick installation.
 Direct connection to P1/P2 bus, the bus that connects the AC indoor unit and the wired

remote controller.

 Multiple objects for control and status (bit, byte, characters…) with KNX standard

datapoint types.

 Status objects for every control available.
 Special Modes available (Power, Economy, Additional Heating and Additional Cooling).
 Timeout for Open Window and Occupancy. Sleep function also available.
 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 remote controller of the AC unit and by

KNX.

 Up to 5 scenes can be saved and executed from KNX, fixing the desired combination of

Operation Mode, Set Temperature, Fan Speed, Vane Position and Remote Controller
Lock in any moment by using a simple switching.

 Four potential-free binary inputs provide the possibility to integrate many types of

external devices. Also configurable from ETS, they can be used for switching, dimming,
shutter/blind control, and more

2. Connection

Connection of the DK-RC-KNX-1i to the AC indoor unit

2.1 DK-RC-KNX-1i without DAIKIN Remote Controller

The DK-RC-KNX-1i can be connected directly to the P1/P2 bus of the indoor unit (no Daikin
remote controller -RC from now on- also connected in the P1 P2 bus). If this is the case, DK­RC-KNX-1i must be configured as master (using the ETS software), see connection diagram
below.

2.2 DK-RC-KNX-1i with DAIKIN Remote Controller

If a Daikin remote controller (RC) is present and connected to the P1/P2 bus, there are two
configuration options:

 If we want to use the RC as master, its PCB switch must be set at “M” position and the

DK-RC-KNX-1i must be configured as slave.

 If we want to use the RC as slave, its PCB switch must be set at “S” position and the

DK-RC-KNX-1i must be configured as master.

Check compatible Daikin remote controllers in the link provided in section 6.

Figure 2.1 Daikin RC PCB backside, MAIN/SUB switch

Special mention must be made with the use of Daikin’s IR wireless remote controllers, in this
case Daikin’s IR must be slave and the DK-RC-KNX-1i must be master, otherwise not all the
features will be available from KNX.

Disconnect mains power from the AC unit and use a 2 wire cable with a diameter of 0.75mm2
to 1.25mm2 for the connection of DK-RC-KNX-1i, Daikin’s remote controller and its
corresponding indoor unit. Screw the suitably peeled cable ends in the corresponding P1/P2
terminals of each device, as summarized in the Figure 2.2.

Maximum P1/P2 bus length is 500 meter. DAIKIN RC and DK-RC-KNX-1i are polarity
insensitive.

Connection of the DK-RC-KNX-1i to the KNX bus:

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

Reconnect power of the KNX bus, and mains power of the AC unit.

4.1 General dialog

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

The first field shows the URL where to download the database (or pr3) and the user manual
for the product.

4.1.1 DK-RC-KNX-1i is master in P1/P2 bus

This parameter changes the gateway’s behavior, being able to program it as master or slave
in P1 P2 bus.

o If set to “no”, the gateway will work as a slave and it will be necessary to have a BRC

remote controller configured as a master.

o If set to “yes” the gateway will be master of the bus. It is not necessary to have any BRC

remote controller in this case but, if there are, they must be configured as slaves. The
next parameter is also shown when selecting DK-RC-KNX-1i as master in P1 P2 bus:

Figure 4.3 Parameter detail

 If VRV system, indoor unit is slave of Operating Mode:

VRV indoor units can be configured as master or slave of Operating Mode.

If configured as slave = “yes”, the unit will take the operating mode of the master
indoor unit in the system (i.e. if master unit is in Heat mode, slaves will be also in
Heat mode).

If configured as slave = “no”, it means is the master unit, then the unit will take the
operating mode selected through the BRC or DK-RC-KNX-1i, and the other slave indoor
units will adopt this operating mode.

Important: Only ONE indoor unit can be configured as master of operating mode. If

more than one indoor unit is configured as master, the system will not work properly.

There are some compatible Operation Modes that slave indoor units can use while the
master indoor unit is operating in another one:

4.1.2 Send READs for Control_ objects on bus recovery

When this parameter is enabled, DK-RC-KNX-1i will send READ telegrams for the group
addresses associated on its Control_ objects on bus recovery or application reset/start-up.

o If set to “no” the gateway will not perform any action.
o If set to “yes” all Control_ objects with both Transmit (T) and Update (U) flags enabled

will send READs and their values will be updated with the response when received.

Figure 4.4 Parameter detail

 Delay before sending READs (sec):

With this parameter, a delay can be configured between 0 and 30 seconds for the
READs sent by the Control_ objects. This is to give time enough to other KNX devices
on the bus to start-up before sending the READs.

4.1.3 Scene to load on bus recovery / startup

This parameter executes a selected scene on bus recovery or startup, only if the selected
scene has an enabled preset or values previously saved from KNX bus (see Scene
Configuration dialog).

If the gateway is disconnected from the indoor unit (P1 & P2 bus not connected) the scene
will not be applied, even when connecting to the indoor unit again.

Figure 4.5 Parameter detail

4.1.4 Disallow control from remote controller

This parameter allows:

1- Having the remote controller always locked, or
2- Decide through a new communication object if the RC is locked or not.

o If set to “yes” all the actions performed through the remote controller will be disabled.

o If set to “no” the remote controller will work as usually. It also appears a new parameter

and the communication object Control_ Lock Remote Control.

Figure 4.6 Communication object and parameter detail

 Enable comm obj “Ctrl_ Remote Lock”:

If set to “no” the object will not be shown.

If set to “yes” the Control_ Lock Remote Control object will appear.

 When a “1” value is sent to this communication object, the remote controller

is locked. To be unlocked a “0” value must be sent. The gateway remembers
the last value received even if a KNX bus reset/failure happens.

Important: If an initial scene is enabled and it has as Value for Remote Lock

(unchanged) or unlocked, this would unlock the remote controller because the
initial scene has priority over the Control_ Lock Remote Control communication
object.

4.1.5 Enable func “Control_ Lock Control Obj”

This parameter shows/hide the Control_ Lock Control Obj communication object which,
depending on the sent value, locks or unlocks ALL the Control_ communication objects except
itself.

o If set to “no” the object will not be shown.
o If set to “yes” the Control_ Lock Control Objects object will appear.

 When a “1” value is sent to this communication object, all the Control_ objects

will be locked. To unlock a “0” value must be sent, as the gateway remembers
the last value received even if a KNX bus reset/failure happens.

4.1.6 Enable func “Operating Hours Counter”

This parameter shows/hides the Status_ Operation Hour Counter communication object which
counts the number of operating hours for the DK-RC-KNX-1i.

o If set to “no” the object will not be shown.

o If set to “yes” the Status_ Operation Hour Counter object will appear.

 This object can be read and sends its status every time an hour is counted. The

gateway keeps that count in memory and the status is sent also after a KNX
bus reset/failure. Although this object is marked as a Status_ object it also can
be written to update the counter when needed. To reset the counter should be
written a “0” value.

Important: This object comes by default without the write (W) flag activated.

If is necessary to write on it, this flag must be activated.

Important: This object will also return its status, every time a value is written,

only if it’s different from the existing one.

Important: If the stored value is 0 hours, the gateway will not send the status

to KNX.

4.1.7 Enable object “Error Code [2byte]”

This parameter shows/hides the Status_ Error Code communication object which shows the
indoor unit errors, if occurred, in numeric format.

o If set to “no” the object will not be shown.
o If set to “yes” the Status_ Error Code [2byte] object will appear.

 This object can be read and also sends the indoor unit error, if occurred, in

numeric format. If a “0” value is shown that means no error.

4.1.8 Enable object “Error Text Code [14byte]”

This parameter shows/hides the Status_ Error Text Code communication object which shows
the indoor unit errors, if occurred, in text format.

o If set to “no” the object will not be shown.
o If set to “yes” the Status_ Error Text Code object will appear.

 This object can be read and also sends the indoor unit error, if occurred, in text

format. The errors shown have the same format as at the remote controller and

at the error list from the indoor unit manufacturer. If the object’s value is empty

that means no error.

Figure 4.7 Default Mode Configuration dialog

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

The byte-type communication object for Mode works with the DTP_20.105. Auto mode will be
enabled with a “0” value, Heat mode with a “1” value, Cool mode with a “3” value, Fan
mode with a “9” value and Dry mode with a “14” value.

4.2.1 When mode is AUTO Status_ objs report actual operating status

This parameter shows the real status of the indoor unit when Auto mode is enabled.

o If set to “no”, when the indoor unit is set to Auto mode, all the Status_ objects concerning

mode will only show Auto enabled.

o If set to “yes”, when the indoor unit is set to Auto mode, all the Status_ objects

concerning mode will show the real mode which the machine is working (Cool, Heat, Dry,
Fan). In case of the bitfield objects, also the Status_ Mode Auto will be shown enabled
with a “1” value.

4.2.2 Enable use of Heat / Cool bit-type obj

This parameter shows/hides the Control_ and Status_ Mode Cool/Heat communication
objects.

o If set to “no” the objects will not be shown.
o If set to “yes” the Control_ and Status_ Mode Cool/Heat objects will appear.

 When a “1” value is sent to the Control_ communication object, Heat mode

will be enabled in the indoor unit, and the Status_ object will return this value.

 When a “0” value is sent to the Control_ communication object, Cool mode

will be enabled in the indoor unit, and the Status_ object will return this value.

4.2.3 Enable PID-Compat. Scaling Mode Objects

This parameter shows/hides the Control_ Mode Cool & On and Control_ Mode Heat & On
communication objects.

o If set to “no” the objects will not be shown.
o If set to “yes” the Control_ Mode Cool & On and Control_ Mode Heat & On objects will

appear.

 These objects provide compatibility with those KNX thermostats that control

the demand of heating or cooling by using scaling (percentage) objects. In
these thermostats, the percentage demand is meant to be applied on a fluid
valve of the heating / cooling system.

 DK-RC-KNX-1i device does not provide individual control on the internal parts

of the indoor unit (as can be its compressor, refrigerant valves, etc). Rather, it
provides the same level of control as a (user) remote controller.

 Objects “Control_ Mode Cool & On” and “Control_ Mode Heat & On” intend to

bring compatibility between thermostats oriented to the control of custom
heating / cooling systems and ready-made AC indoor units, by applying the
following logic:

 Whenever a non-zero value (>0%) is received at “Control_ Mode Cool

& On”, indoor unit will switch On in COOL mode.

 Whenever a non-zero value (>0%) is received at “Control_ Mode Heat

& On”, indoor unit will switch On in HEAT mode.

 Lastest updated object will define the operating mode

 Indoor unit will switch off only when both objects become zero (0%) –

or when an OFF is requested at object “0. On/Off [DPT_1.001 - 1bit]”

Important: These objects function is only to send On/Off and Cool/Heat to the indoor

unit. The PID (Inverter system) is calculated by the indoor unit itself. Please consider
introducing an appropriate PID configuration to the external KNX thermostat to not
interfere the indoor unit PID.

Figure 4.10 Default Special Modes Configuration dialog

The Special Modes can be parameterized through the ETS parameters dialog, and they can
be used to give extra functionality.

Important: When executing any of the Special Modes, the real state of the indoor unit

will NOT be shown in KNX.

Important: When the predefined time for the Special Mode is finished or a “0” value is

sent to stop it. The previous state will be recovered.

Important: If a value concerning On/Off, Mode, Fan Speed or Setpoint Temperature is

received from KNX while any Special Mode is running (“1”), the Special Mode will stop
and the previous state will be recovered. The value received will be also applied then.

Important: If a value concerning On/Off, Mode, Fan Speed or Setpoint Temperature is

modified through the remote controller, the Special Mode will stop WITHOUT recovering
the previous state. Then the real indoor unit state will be shown in KNX including the new
value received through the remote controller.
