Introduction
The Danfoss Link HP kit (HP)* is one of the accessories available for Danfoss Link™. The kit enables your
heat pump to communicate wirelessly** with other Danfoss Link™units in your heating system. An
example of a wireless solution for DHP-H is shown in the gure below.

* The heat pump kit can also be used with Danfoss Online 2, with the exception of product numbers
086L2381 and 086L2382.
** Please note that all buildings may have obstructions which can impact on communication and the
maximum transmission distance. If you encounter problems with wireless communication, the wireless
signal can be amplied by means of Danfoss Link CF-RU repeater units.

Note the following when installing the Danfoss Link™HP kit:
•Installation and positioning must be done in accordance with applicable laws and regulations.
•The Danfoss Link™HP kit only works in conjunction with heat pumps DHP-H/L/A 2009 or later, using soft-
ware version 1.34 or later, and DHP-AQ with software version 2.2 or later. The Danfoss Link™HP kit is not
suitable for heat pumps with a cooling function (DHP-C and heat pumps with a cooling module).
Tip!
• The
?
key on the Danfoss Link™ CC panel can be used at any time during installation.
• Always check for the latest software version at www.link.danfoss.com before installation. See the section on software
upgrades in the Danfoss Link™ CC Installation Manual.

Danfoss Link™CC is used to control the system. Ensure that this control unit has the latest software
installed to avoid problems when installing the HP kit.
1. Check the software version on the control unit display. Press the left arrow
on the heating pump control until the display changes to “Service menu”.
2. Press “minus” until the cursor reaches the “Version” menu.
3. Press the “right arrow”. This will bring up the software version in the display.

Danfoss HP kit for DHP-AQ
The installation kit q for the DHP-AQ series consists of a power supply, where a DIN rail is connected to
the DHP-AQ control (MAXI +60, MIDI or MINI). The DCM03 unit w is wall-mounted outside the control unit
so that it can communicate wirelessly with the Danfoss Link TM CC 3 panel. The Danfoss Link™CC epanel
communicates with the other Danfoss Link™ components in the heating system.
An example of a heating system with wireless units is shown in the gure below. The Danfoss Link™
components are indicated with a dotted line.

Connection to Danfoss Link™ CC
CBefore connecting to a power outlet, make sure that the electrical installation has been carried out
correctly and that there is no risk of injury or damage.
Note!
The heat pump must be added to the network as a service unit. For more information about connecting to
networks see the accompanying Danfoss Link™ CC Installation Manual.
Add any dedicated repeaters (CF-RU) BEFORE adding the heat pump to the wireless network.
Note!
During installation, the distance between Danfoss Link™ CC and DCM03 must not exceed 1.5 metres.

Once the installation is complete, a network test must be carried out to ensure that communication
between all added units and Danfoss Link CC™ is stable.
Note! Do not carry out the network test until Danfoss Link™ CC has been tting in its nal position.
When the network test completes, Danfoss Link™ CC waits for the battery-powered units to be activated
and registered. Follow the on-screen instructions. If the network test completes without problems, no
further interaction will be required. If the network test runs slowly, Danfoss Link™ CC will guide you
through the troubleshooting procedures and provide useful tips as to how to speed up the process.

Troubleshooting
If an error occurs in communication with the GateWay card, the heat pump and DCM03, this may be
indicated in a number of dierent ways.
If the heating system is in operation when the error occurs, a yellow warning icon will be shown in the
Danfoss Link™CC display.
Refer to the instructions in chapter 7.1 in the installation manual for Danfoss Link™CC for more information
about the error and suggestions for suitable remedial measures.
If the wireless communication between Danfoss Link™CC and DCM03 does not work, check the follow-
ing:
1. Cable connections
2. Check that the units are connected to the mains and that they are switched on (LEDs illuminating
correctly).
3. Check that DCM is set to Danfoss Link™integration and not to Danfoss Online. By pressing the DCM
button quickly three times, you will switch between showing status for Danfoss Online and Dan-
foss Link™integration. The LEDs on DCM03 (both red and green) flash rapidly 3 times when status
changes from Danfoss Online to Danfoss Link™integration. When switching from Danfoss Link™
integration to Danfoss Online, the lights flash twice and more slowly.
4. Check LED on the GateWay card:
•Start-up: Flashing, on 90% off 10%.
•Approval DCM-HP: on 50% off 50% (rapid).
•Approval failed: on 75% off 25% (flashes twice (slowly) with a long pause in between).
•Send settings to DCM: on 50% off 50% (slow).
•Everything OK: 100% (constant light).
5. Check whether DCM03 has been registered correctly in the Danfoss Link CC™panel in accordance
with the Danfoss Link™CC Installation Manual, Chapter 4, ”Adding service units”.
6. Has a network test been performed to check whether all units in the heating system are working? See
the Danfoss Link™CC Installation Manual, Chapter 4.9 “Performing a network test”.
7. There may be too much distance between DCM03 and Danfoss Link™CC, or wireless communica-
tion may be obstructed because of physical objects or other obstructions. Try a new location for the
DCM03 until a good signal strength is obtained. If this is not possible due to physical components
of the building, use a repeater (CF-RU). Install this repeater between the Danfoss Link™CC and the
DCM03 unit.
8. In rare cases, it may be necessary to delete the heat pump as a service unit and then re-install it.
Follow the instructions in Chapter 5.3 in the Danfoss Link™CC Installation Manual about how to
remove a service unit.
9. The faulty component in the HP kit may need to be replaced. First, delete the service unit as
described in the Danfoss Link™CC Installation Manual. Next, add a replacement unit.
NOTE! If you restore the factory settings, you must also re-install all the units.
