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 actua-
tors/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.

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.

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.
