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-

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.

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.

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.

Give the system a little time to adapt...

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.

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.
