Installation Guide Danfoss Link™ SCM

The Danfoss Link™ SCM (Simple Communication Module) is an

electronic controller for turning the Away function ON/OFF in a

Danfoss Link™system.

The Danfoss Link™ SCM is powered by 230 V~.

Introduction

Installation

The Danfoss Link™ wireless system’s transmission range is suf-

cient for most applications; however each building has dierent

obstacles aecting communication and maximum transmission

distance.

If communication problems occur Danfoss suggests to support

the system with repeaters. In exceptional cases the wireless

system may not be suitable for your installation.

Note: Be aware that installation and placement must be according

to local building regulations.

Wiring

The process of adding the Danfoss Link™ SCM

to a system is performed on the Danfoss

Link™ CC.

Note that the Danfoss Link™ SCM

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 (HOME) or red (AWAY)

permanently - depending on input stage.

For further information, see the Danfoss Link™ CC installation

guide.

Note: If adding the Danfoss Link™ SCM to the Danfoss Link™ CC is

unsuccessful, make sure the right Danfoss Link™ CC software

version is applied. Correct version: 2.5.57 or higher.

The away temperature can only be set on the Danfoss Link™ CC,

default setting is 15° C.

A SIM-card for the Danfoss Link™ Mobile Phone Butler is not

included. Before inserting the SIM-card please remember to dis-

able the PIN-code.

System test

After installation it is recommended to perform a

system test by texting (0000#0) to the Danfoss Link™

MPB in order to set the Danfoss Link™system to AWAY

mode (OFF).

On the Danfoss Link™ MPB and the SCM the AWAY mode is

indicated by a red LED. On the Danfoss Link™ CC the AWAY mode

is indicated by the suitcase icon.

After 10 minutes the AWAY mode screen will be replaced by the

Standby screen for security reasons.

Send another text message (0000#1) to revert the system to

the HOME mode (ON). The LED turns green and the AWAY icon

disappears. See the Danfoss Link™ MPB User Manual for further

information.

Smartphone app

For Android phones and iPhones you can download the Danfoss

ButlerApp for easy communication with the Danfoss Link™ MPB.

Other ON / OFF devices like sensors, manual switches, etc.

can also be used and connected to the SCM for turning

AWAY mode ON / OFF in the Danfoss Link™ system. The

ON / OFF device must be connected to the SCM via its NC and

COM slots.
