Installation Guide Danfoss Link™ DBR Installation Guide Danfoss Link™ DBR
The Danfoss Link™ Dynamic Boiler Relay (DBR) is an electronic
device for turning gas and oil boilers ON/OFF depending on
heat demand.
The Danfoss Link™ DBR must in applications with bypass valve
such as AVDO, be installed in combination with the ESM-11
temperature sensor (included inside the box) for turning the
boiler ON/OFF based on heating demand and water tempera-
ture in return pipe for running the system at optimal energy
efficiency.
This pack includes:
1 x Danfoss Link™ Dynamic Boiler Relay
1 x ESM-11 Temperature Sensor
Introduction
Installation
The Danfoss Link™ wireless system’s transmission range is suffi-
cient for most applications; however each building has different
obstacles affecting communication and maximum transmission
distance. If communication problems occur Danfoss suggests
that accessories 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.

Note:
· The ESM-11 Temperature Sensor needs to be mounted on the
return pipe.
·Mount the ESM-11 Temperature Sensor in the bypass circuit
(figure 1) and not outside of the circuit (figure 2). Pay attention
that the ESM-11 must be outside the circuit of an eventual stor-
age tank
