3 Safety instruction
Make sure that the mains power supply to the thermostat is shut o
before starting the installation.
Important: When the thermostat is used to control a oor heating
element, always use a oor sensor, and never set the maximum oor
temperature to more than the manufacturer recommends for the specic
ooring type. The device is limited to 35 °C oor temperature, due to
compliance requirements. In special cases the limit can be extended
to 45 °C oor temperature after the unrecoverable breakout has been
performed. Based on the setup in the app the thermostat has maximum
temperature limitations imposed based on our recommendations.
• Electrical heating thermostats must always be installed according to
local building regulations and wiring rules. Installation must be carried
out by an authorized and/or qualied installer.
• The thermostat must be used in a wall mounted installation supplied
through an all-pole disconnection switch (fuse).
• Do not expose the thermostat/switch to moisture, water, dust, and
excessive heat.
• This thermostat/switch can be used by children aged from 8 years and
above and persons with reduced physical, sensory or mental capabilities
or lack of experience and knowledge, if they have been given supervision
or instruction concerning use of the appliance in a safe way and
understand the hazards involved, by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with
the thermostat/switch.
• The device is designed for permanent operation.

4 Installation Guidelines
Follow these guidelines when placing the thermostat.
Install the thermostat in a suitable height on the wall
(typical 80 – 170 cm)
Do not place the thermostat on the inner side of a poorly
insulated exterior wall.
Install the thermostat more than 50 cm from window
and door openings

8INSTALLATION GUIDE
DEVIreg™ Room
Do not place the thermostat in a way that it will be
exposed to direct sunlight.
The thermostat must not be installed in direct wet
areas (Zones 0, 1 and 2).Always follow local regulations
regarding IP classes, this doesn’t mean that the
thermostats can’t be installed in bathrooms.
Do not position the oor sensor close to door openings
or at places where the sunlight or other heat sources are
located in the oor.

Installation steps
Description Illustration
1. Unpack the thermostat. Make
sure all parts are delivered
(1 pc. thermostat unit ,1 pc.
Power supply, 1 pc. Frame, 1 pc.
Frame adapter, 1 pc. Spacer, and
1 pc. wire sensor) along with
the instructions written in local
ocial language.
2. Place the oor sensor in the
Flexpipe and make sure the
sensor element is properly xed
inside a Flexpipe. The Flexpipe
must guide the sensor cable all
the way to the wall/connection
box. Our mats have this product
included. sold separately as
(140F1114).

3. The bending radius for the
Flexpipe must be more than
50 mm.
4. Make sure the oor sensor is
located with equal distances
between two heating
cables (> 2 cm) located at a
representative position.
5. For thin oor constructions:
the Flexpipe should be ush
with the sub-oor surface,
countersink the Flexpipe if
possible.
For thicker constructions: the
Flexpipe including the sensor
should be located such that
the sensor is exposed to a
representative heating level,
our recommendation is still
that the sensor must be located
equidistant between the cables
or mat runs.

Selecting the timer schedule / app communication mode the device will
be connectable in the DEVI control app, the communication is done via
Bluetooth 4.2, where temperatures, settings, schedule, limits and more
can be set to the desired level.
Selecting the OFF mode will disable the thermostat completely.
When the thermostat is in all other positions than Timer schedule/App
communication the app can only display limited information, in OFF the
app and thermostat will be completely OFF and nothing will be indicated
or communicated to the app.
To pair the thermostat with the app, place the thermostat in the App
communication position and start the process in the app , the device will
blink with the communication indicator. After the app has initiated the
communication with the thermostat, the user needs to turn the dial out
to manual temperature setting and back into the App communication
position, this is to validate with what thermostat the paring is wanted.
