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.

Electric heating devices are not supported.

Installation Guide Danfoss Link™ DBR

Introduction

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 temperature 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

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 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.

Installation in application with bypass valve using AVDO

In installations with bypass using AVDO, remember to mount and wire the ESM-11 Temperature Sensor included in the pack.

Note:

· The ESM-11 Temperature Sensor needs to b e mounted on the return pipe.

·Mount t he ESM-11 Tempe rature Sensor in the bypass circuit (gure 1) and not outside of the circuit (gure 2). Pay at tention that the ESM -11 must be o utside the circuit of an e ventual storage tank

Installation Guide Danfoss Link™ DBR

The Danfoss Link™ DBR is not recommended in application

without bypass valve. Install Danfoss Link™ DBR together with e.g. AVDO bypass valve.

If boiler has internal bypass valve and installed with weather compensation, the Danfoss Link™ DBR can be installed without

the Return Sensor, in operation mode “On when Heat Demand”

Mounting

Note: The Danfoss Link™ DBR must be mounted on a at surface.

For mounting the temperature sensor correctly on the pipe please see enclosed installation guide for ESM-11 Temperature

Sensor.

Adding the device

The process of adding the D anfoss Link™ DBR to a system is performed on the Danfoss Lin k™ CC. Note that the Danfoss Link™ DBR 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 D anfoss Link™ CC instruction manual.

Note: If adding the D anfoss Link™ DBR to the Danfoss Link™ CC is

unsuccessful, make sure th e right Danfoss Link™ CC software version is applied. Correct ver sion: 4.1.0 or higher.

according to the application

Congure the Danfoss LinkTM DBR Operation Mode

Dynamic Control (Recommended)

When Dynamic Control is selected, the on/o cycles are determined by the heat demand in the rooms and the temperature of the return pipe into the boiler to optimize energy savings. Recommended in systems with bypass in heating circuit, such as AVDO valve. It is possible to adjust the Setpoint Limits in this mode. Dynamic Control only possible to select with ESM11 sensor mounted on return pipe

On when Heat Demand

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. Select ‘Cycle Time’ in Settings.

Setpoint Limits

The recommended Maximum Temperature is below 54 degrees to ensure maximum eciency with condensing boilers. If Maximum Temperature is set too low, there is a risk of not reaching the desired temperature.

Congure the Minimum Temperature and Maximum temperature for Return Line setpoint temperatures for

Danfoss Link™ DBR here. (Note: You can only set these setpoint limits within the Dynamic mode.)

Cycle time

• 6 cycles/hour is recommended for condensing non-modulating gas boilers.

• 3 cycles/hour is recommended for condensing non-modulating oil boilers.

Perform network test

Once the Danfoss Link™ DBR 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™ DBR will go into safety mode. In this mode the boiler will be turned ON continuously.

Factory reset

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.
