DEVIlink™ FT
1 Introduction
The DEVIlink™ FT (Floor Thermostat) is a device for switching the heating element ON/OFF. In connection with a floor
sensor it can also measure the temperature in the floor
(FTS). Secondly you have the possibility to use the FT as
a on and off switch to other equipments manually or by
schedule.
Installation scenario:

2 Placement of DEVIlink™ FT
Installation and placement must be according to local
building regulations.
2�1 Operation mode
DEVIlink™ FT supports two types of operation modes.
1. Heating regulation
1. On/OFF switching
When used in heating regulation mode you have to consider the following advices for controlling the heating.
When used as simple ON/OFF mode do not connect floor
sensor.
2�2 Sensor combination
When installing the DEVIlink™ FT you need to consider the
type of heating and thus which sensors should be used.
There are three options:
Installation Guide4
DEVIlink™ FT
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 DEVIlink™
RS. Choose Combined regulation when doing the
configuration on the DEVIlink™ CC.
3. No floor sensor: A floor sensor is not present, and
cannot be installed. You must install a DEVIlink™ RS.
Choose Room regulation.
Be aware that temperature control is less accurate without
the floor sensor and that all DEVIlink™ FTs in a room need to
havethe same sensor configuration.
DEVI recommends always installing a floor sensor.
Do not install floor heating system without a floor sensor
when the heating element is installed on or beneath wooden
surfaces and other surfaces sensitive to temperature!
