Installation

The Danfoss Link™ wireless system’s transmission range is

suﬃcient 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.

Please be aware of the following, when installing Danfoss

Link™ FT:

Installation and placement must be according to

local building regulations.

Installation

Operation mode

Danfoss Link™ FT supports two types of operation modes:

1. ON/OFF switching: do not connect a ﬂoor sensor with

Danfoss Link™ FT in this modus.

2. Heating regulation: when installing the Danfoss Link™ FT

you have to consider the type of heating and thus which

sensors should be used.

There are three options:

1. Comfort heating: Constant temperature on the ﬂoor in

bathrooms and other rooms where a comfortable warm

surface is required. Install the Floor sensor and choose Floor

regulation for the room when doing the conﬁguration.

2. Total heating: Control of room temperature in living rooms

etc. Install the ﬂoor sensor and a Danfoss Link™ RS. Choose

Combined regulation when doing the conﬁguration on the

Danfoss Link™ CC.

3. No ﬂoor sensor: A ﬂoor sensor is not present, and cannot

be installed. You must install a Danfoss Link™ RS. Choose

Room regulation.

Be aware that temperature control is less accurate without a

ﬂoor sensor and that all Danfoss Link™ FT in a room need to

have the same sensor conﬁguration.

Danfoss recommends always installing a ﬂoor sensor.

Note! Do not install electric ﬂoor heating system without a ﬂoor

sensor, when the heating element is installed on or beneath

wooden surfaces and other surfaces sensitive to temperature!
