Installation Guide

Connections

Make sure that all connections to the Danfoss Link™ HC are completed, before connecting to a 230 V
power supply.
1: Connecting actuators (24 V)
If NC (normally closed) actuators are installed for ON/OFF regulation, no further actuator output con-
figuration is needed.
1. Connect actuator wires to an output.

2: Connecting pump and boiler controls

The relays for pump and boiler are potential free contacts and can thus NOT be used as direct power
supply. Max. load is 230 V, 8 (2) A.
1. Connect wires for pump and boiler controls to their
respective output.

3: Connections for Away Function

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.
1. Connect an external ON/OFF switch to the termi-
nals for Away Function. When this switch is closed
(ON) the system will override all room thermostat
set points and change it to 15°C.
