2. Introduction
Danfoss Link™ is a wireless control system for a variety of heating systems.
The Danfoss Link™ HC is a part of this system allowing wireless control of manifolds for water based
floor heating/cooling.

Output cable fixing.
4. Mounting and Installation Procedure (Sequential)
The wireless systems transmission range is sufficient for most applications; however, wireless signals
are weakened on the way from the Danfoss Link™ to the Room Thermostats and each building has
different obstacles.
Checklist for optimal installation and best wireless signal strength (fig. 1):
• No metal objects between the Danfoss Link™ HC and the Room Thermostats.
• Wireless signal through walls on shortest possible diagonal distance.
• Optimise the wireless signal by installing a RU Repeater Unit.
Note! Danfoss recommends that an installation plan is made before beginning the actual installation (fig. 1).
Mount the Danfoss Link™ HC, connect
all actuators (TWA) and power-up the
unit

Installation Guide Danfoss Link™ HC
4.1 Danfoss Link™ HC
Mount the Danfoss Link™ HC in an horizontal upright position.
Wall:
• Remove the front and side covers (fig. 3).
• Mount with screws and wall plugs (fig. 3).
DIN-Rail:
• Mount DIN-rail parts (fig. 4).
• Click on DIN-rail (fig. 5).
• Release from DIN-rail (fig. 6).
Important! Complete all the installations on the Danfoss Link™HC as described below, before connecting
to a 230 V power supply!
4.2 24 V Actuators
• Connect the two actuator wires to an output (fig. 7).
• Fix the cable (fig. 8).
Note! If NC (normally closed) actuators are installed for ON/OFF regulation, no further actuator output
configuration is needed.
4.3 Relays for Pump and Boiler Control
• Connect wires for pump and boiler controls to their respective output (fig. 9).
• Fix the cable (fig. 10).
Note! The relays for pump and boiler are potential free contacts and can therefore NOT be used as direct
power supply. Max. load is 230 V and 8 A/2 A!
4.4 Input for Away Function
• Connect an external ON/OFF switch to the terminals for Away Function (Input 2). When this switch
is closed (ON) the system will override all room thermostat set points and change the temperature
to 15 °C (fig. 11).
• Fix the cable (fig. 12).
Note! The Away Function ensures a set room temperature fixed at 15 °C for all room thermostats, but it
can be changed with the Danfoss Link™CC.
4.5 Input for Heating and Cooling
• Connect an external ON/OFF switch to the terminals for Heating and Cooling (Input 3) (fig. 13).
With the switch closed (ON), the system will switch from heating to cooling mode.
• Fix the cable (fig. 14).
Note! With the system in cooling mode, the actuator output will be activated (ON for NC actuators/OFF
for NO actuators), when the temperature in a room exceeds the set point.
When the system is in cooling mode a dew-point sensor should be installed.

4.7 Power Supply
Connect all actuators (TWA), before mains powering the unit!
Then, connect the Danfoss Link™ HC power supply plug to a 230 V power supply, when all actuators,
pump and boiler controls and other inputs are installed. The Danfoss Link™ HC is now ready to be
added to the Danfoss Link™ CC.
Note! If the power supply plug is removed from the power supply cable during installation, ensure that the
connection is made according to existing law/legislation.

4.8 CF-EA External Antenna
The CF-EA is installed as diverter when there is no transmission possible through a large building,
heavy construction or metal barrier, e.g. if the Danfoss Link™ HC is located in a metal cabinet/box.
• Remove the plastic cover from the antenna connection on the Danfoss Link™ HC (fig. 15).
• Connect the CF-EA (fig. 16).
• Place the CF-EA on the other side of the transmission barrier away from the Danfoss Link™HC.
5. Configuration
5.1 Adding Danfoss Link™ HC to the system
Note! Adding Danfoss Link™HC to a system is made from the Danfoss Link™CC.
For further information, see separate instruction.
• Remove the front cover of the Danfoss Link™CC by gently pulling
it off, pull near the edges of the cover.
• Press the SETUP pin for 3 seconds to enter the service area.
Important!
• The Danfoss Link™ HC must be added to the network as a service device. For further instructions on
network inclusion, see more information in the Danfoss Link™ CC Installation Guide.
• Add any dedicated repeater units (CF-RU) BEFORE adding the Danfoss Link™ HC to the wireless network.

5.6 Performing a network test after adding new devices
After finishing installation, perform a network test to ensure that communication between added
devices and the Danfoss Link CC™ is stable.
Note! Do not perform the network test before the Danfoss Link™CC is mounted in its final position.

At the end of the network test the Danfoss Link™ CC awaits for all battery operated devices to wake
up and report. Follow the instructions given on the screen. If the network test is running smoothly,
there will be no need for further interaction. If the network test is performing slow, the Danfoss Link™
CC guides through troubleshooting and gives useful tips for speeding up the process.
