Important information
For safety reasons the heating system must have a bypass
function. This is either built into the boiler or it must be
installed in the system.
Demount other heating control timers in the installation or
they will interfere with the Danfoss Link heating control
algorithm. If weather compensation is present it should be set
to constant comfort.

The Danfoss Link™ BR (Boiler Relay) is a device for turning
gas and oil boilers ON/OFF depending on heating demand.
The Danfoss Link™ BR is powered by 230 V~.
Introduction
Installation Guide Danfoss Link™ BR
Installation
The Danfoss Link™ wireless system’s transmission range is su-
cient for most applications; however each building has dierent
obstacles aecting communication and maximum transmission
distance.
If communication problems occur Danfoss suggests that acces-
sories would be required to support the system, such as repeaters.
In exceptional cases the wireless system may not be suitable for
your installation.
Be aware that installation and placement must be
according to local building regulations.

Installation Guide Danfoss Link™ BR
The process of adding the Danfoss Link™ BR
to a system is performed on the Danfoss
Link™ CC.
Note that the Danfoss Link™ BR
must be added as a Service
Device.
When adding, press and
release the install button,
and observe that the LED
gives a fast green ash.
If adding is successful the LED turns green permanently.
For further information, see the Danfoss Link™ CC instruction
manual.
Note: If adding the Danfoss Link™ BR to the Danfoss Link™ CC is
unsuccessful, make sure the right Danfoss Link™ CC software
version is applied. Correct version: 2.3.27 or higher.

Congure Danfoss LinkTM BR
Select “Manage Devices” in
“Rooms and Devices”.
Select “Congure Device”.
Select Device to congure Press “Congure Heating” to
bring up the heating congu-
ration, which will show the
current heating preferences
and allow them to be edited
by pressing the buttons.

Congure the BR Control Type
Press the “Select Type”
button.
Select one of the modes.
Default BR setting is
“Automatic On/O”.
Automatic On/O:
The boiler is only ON when there is heat demand from a
reference room in the system. Recommended for modulating
boilers and non-condensing boilers.
TPI (Time Proportional Interval):
A duty cycle is calculated and used to control the boiler.
• 6 cycles/hour is recommended for condensing non-modulating
gas boilers.
• 3 cycles/hour is recommended for condensing non-modulating
oil boilers.
Note: If the installation has a mixing shunt for oor heating, it is
recommended to adjust the set point temperature as high as
needed on the coldest day of the year. The TPI control will lower
the supply line temperature to the necessary level needed at all
time. TPI is implemented in Danfoss Link CC software version
2.4.x or higher.

Congure the BR Control Reference Room
Always On:
The boiler is kept ON regardless of heat demands.
From the “Congure Heating”screen it is possible to select the
control reference (i.e. the boiler will be turned ON if any of the
selected rooms call for heat). By default all rooms are selected.
Press the “Select Rooms”
button.
Any number of rooms can be
selected for use as reference.
Room include/exclude is tog-
gled simply by pressing the
room-button.

Status indicator
Turn o the power to the device, then press and hold the install
button in front of the device for approx. 5 sec. while the power
is switched on again. The button must be held until LED gives a
red ash.
Factory reset
Once the Danfoss Link™ BR and all other
devices in the system have been registered
and the Danfoss Link™ CC is placed in its
nal position, perform a network test (see
separate Danfoss Link™ CC manual).
Note: If the connection to the Danfoss Link™ CC
is lost for more than 1½ hour, the Danfoss
Link™ BR will go into safety mode. In this
mode the boiler will be turned ON continuously.
