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.

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
