Installation Guide Danfoss Link™ HC

1. Quick guide for Installation

Mount the Danfoss Link™ HC, connect all actuators (TWA) and power-up the unit

Create rooms, add outputs and Room Thermostats - choose output type in actuator settings

Add any other devices to the system

2. Introduction

Add Danfoss Link™ HC to the Danfoss Link™ CC as a service device

Check the conguration in Danfoss Link™ HC setting menu

Perform a network test

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 oor heating/cooling.

4. Mounting and Installation Procedure (Sequential)

The wireless systems transmission range is sucient for most applications; however, wireless signals are weakened on the way from the Danfoss Link™ to the Room Thermostats and each building has dierent obstacles.

Checklist for optimal installation and best wireless signal strength (g. 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 (g. 1).

4.1 Danfoss Link™ HC

Mount the Danfoss Link™ HC in an horizontal upright position.

Wall:

• Remove the front and side covers (g. 3).

• Mount with screws and wall plugs (g. 3).

DIN-Rail:

• Mount DIN-rail parts (g. 4).

• Click on DIN-rail (g. 5).

• Release from DIN-rail (g. 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 (g. 7).

• Fix the cable (g. 8).

Note! If NC (normally closed) actuators are installed for ON/OFF regulation, no further actuator output conguration is needed.

4.3 Relays for Pump and Boiler Control

• Connect wires for pump and boiler controls to their respective output (g. 9).

• Fix the cable (g. 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 (g. 11).

• Fix the cable (g. 12).

Note! The Away Function ensures a set room temperature xed at 15 °C for all room thermostats, but it can be changed with the Danfoss Link™ CC.
