Danfoss Link™ DBR Boiler Relay
with ESM-11 temperature sensor
Application
ESM -11
Ordering
The Danfoss Link™ DBR boiler relay is a device for
turning gas and oil boilers ON / OFF, depending
on heating demands.
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.
The ESM-11 temperature sensor has a spring
contact surface to ensure a good heat transfer on
pipes of all sizes. The ESM-11 temperature sensor
is a two-wire device.
Product Code no.

The Danfoss Link™ DBR boiler relay is a mains
powered device and and will act as a repeater in
order to improve the wireless performance of the
Danfoss Link™ network.
The DBR boiler relay is part of the Danfoss Link™
system, which is used for wireless linking and
controlling of heating systems in residential and
light commercial buildings.

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 storage tank.
