Congratulation on the purchase of your new Danfoss Link system

In this user guide, we will explain what the

Danfoss Link system can do and provide you

with good advice and instructions for nding

the settings that t your exact needs.

The Danfoss Link system is designed to make

life easier for you. All sub-systems in your

house communicate with one another via

Danfoss Link™ CC and the system is able to per-

form several tasks without you as a user having

to study loads of technical instructions.

We hope you will spend some time reading

this user guide, to benet most possible of

your Danfoss Link system.

This user guide primarily addresses the house’s

control system. If you would like more specic

information concerning a single unit, please re-

fer to the literature provided with the product.

How the user interface works

“Room 1 here

- I am now set

to 21.5 °C”

“I set the agenda and

coordinate every-

thing. Room 1 - give

me 21.5 °C”

“I am a repeater unit and must

always be turned on. I help the

other units that are located

farthest from the Danfoss

Link™ CC panel to communi-

cat e .”

The Danfoss Link system is operated via a user-

friendly touchscreen.

One common characteristic of the user inter-

face is that you are always made aware where

you are in the menu structure, at the top of the

display.

The “Help” key is located in the bottom right-

hand corner. You can use this to obtain ad-

ditional information about the current given

screen display.

The “Back” key is located in the bottom left-

hand corner, and you can use this to go one

step back in the menu.

By pressing the “X” key, you can undo an

erroneous setting. That’s all it takes, it’s as easy

as that.

We encourage you to explore the system’s set-

tings and screen displays in order to become

familiar with the available options.

I want to adjust the temperature in one room

All rooms that are part of the network can be

adjusted centrally using the Danfoss Link™

panel.

You can also set the temperature using the

actual room device, i.e. the living connect® ther-

mostat on the radiator, or the Danfoss Link™ RS

if you have hydronic oor heating.

Please note: If you have a Danfoss Link™ RS in combination

with a living connect® thermostat in the same room,

the desired room temperature is set using only the

room sensor.

Please note: Be aware that hydronic oor heating is a

relatively slow-acting heat source. It may

take as long as 8 hours for the desired room

temperature to be reached.

If you have a radiator, you should be aware

that the temperature you set is reached

locally, in the area in which the radiator

is installed or where the room sensor is

mounted. Thus, minor adjustments may be

needed.

With the living connect®

thermostat, you can set the

desired room temperature

locally using the thermostat.

If you have two thermostats

in the same room, they will

synchronise automatically.

dard with oor heating sys-

General system information

I want to save energy

Danfoss Link makes saving energy easy with-

out having to compromise in terms of comfort.

Why maintain a high room temperature when

you’re not at home?

Lowering the room temperature by one de-

gree will reduce your heating costs by approx.

5%.

For this reason it makes perfect sense to use

the weekly schedule, which automatically

sets the desired At Home temperatures when

you’re at home, and the desired Away/Asleep

temperature when you’re away.

If you have radiator heating, you can experi-

ment with signicant temperature reductions

(e.g. from 21 ˚C to 17 ˚C) in Away/Asleep mode.

If you have hydronic oor heating, you should

not lower the temperature by more than 1-2 ˚C,

as the cooling/heating time is very long.

1˚C

How the weekly schedule works

This function requires you to set two basic

temperatures; one At Home temperature,i.e.

the desired temperature for when you’re at

home, as well as one Away/Asleep tempera-

turefor when you’re out of the house or sleep-

ing at night.

If you like, it is also possible to set various At

Home and Away/Asleep temperatures for

each room in your house.

The weekly schedules can be set for each

room, and you can of course copy your set-

tings from room to room, as well as setting al-

ternating periods for weekdays and weekends.

The schedules are set directly via the “period

arrows” on the screen, and you can remove or

set new periods as needed.

The At Home period is activated at the times of day when you are at home.

The Away/Asleep period can be activated e.g. overnight, when most people prefer slightly cooler temperatures.

Not so fast - what happens if I come home early one day?

What happens when I change a local setting in a room?

Does the Danfoss Link™ CC remember the new setting?

If you are not using the weekly schedule, the

If you are running the weekly schedules and

come home during an Away/Asleep period,

you will most likely nd it necessary to turn up

the temperature. This is possible of course, but

the system will consider this to be an excep-

tion from the rule and not a general prefer-

ence.

Our everyday lives do not always run accord-

ing to plan, and sometimes we’re forced to stay

home, say, with a sick child. In such situations,

we don’t want the system to lower the tem-

perature during daytime hours.

In this case, all you have to do is select At

Home on the menu’s start page, and select the

specic rooms in the house, these will then be

set to their At Home temperatures.

The At Home mode will remain active until you

turn it o, so if you use the weekly schedule

function to save energy, remember to turn o

At Home again.

If you use the weekly schedule and change the

temperature during a At Home period, then

this may be a general preference for a dierent

temperature. This type of modication will be

permanently saved and will thus become the

new standard At Home temperature for the

room in question.

Please note: This describes the factory settings; your

installer may have set the system up to also

remember modications made locally during

an Away/Asleep period.

The rst week after the system is started up in

weekly schedule, it will take a bit of time for it

to become familiar with its new surroundings.

It is during this rst week that the Danfoss Link

system learns how quickly the dierent rooms

can be heated.

For example, if you set your weekly schedule

to 21 ˚C at 3 pm, the system uses the informa-

tion it has gathered to determine when to be-

gin a reheating cycle as well as how to account

for seasonal temperature dierences.

General system information

We’re going on holiday; how should we set the system?

It’s quite simple: all you have to do is press the

Vacation key on the initial menu display.

The Vacation function puts the entire house

in hibernation mode, in which all sub-systems

drop to a controlled, low operating point, with-

out the risk of moisture damage, frost damage

or the like.

You can set the Vacation function to start -

and stop at a desired date/time. The system

will automatically return to your preferred set-

tings in advance, so that you return to a com-

fortable warm house.

You can set the Vacation function to apply for

the entire house or to selected rooms only.

If you return home earlier than expected, you

can cancel the Vacation function on the main

screen.

Does the Danfoss Link system have a tamper-proof lock?

Yes. It is possible to use a tamper-proof lock for

the individual room units.

All you have to do is select the Customize

Room on the individual rooms. Next, select

Room Restrictions, which will allow you to set

a maximum and minimum temperature that

can be set from the room in question; alterna-

tively, you can block local room operation all

together. If you have room sensors, you can

also deactivate the heat stop function on the

room sensor.

Pause! I need a break in my schedule ...

If you need to take break from your normal

routine, to air the house for example, then use

the Pause function.

The temperature of the entire system is low-

ered to the safest minimum. You choose if this

is for just one hour or indenitely. To turn o

the Pause function simply turn o the mode.

Changing the time, date, sound or display

If you would like to change the date and time

or modify the display appearance or sound of

the user interface, you can do so in Settings

located under the House control menu.

Uh oh - the batteries are dead. Now what happens?

When the battery-operated units are close to

running out of power, an alarm will be issued

on the central control panel well before the

batteries are completely used up.

The system will not“forget” anything even if a

unit temporarily loses power.

In the event of a battery-operated unit running

completely out of power, the unit will set the

room to a certain temperature before the bat-

teries die.

Please note: Danfoss recommends the use of non-

rechargeable, alkaline batteries (2 x AA per

room unit), for which you can expect an

average battery lifetime of 2 years.
