... your DEVI floor heating system
Your property has been installed with a DEVI electric floor
heating system. DEVI is Europe’s leading floor heating manu-
facturer, with over 45 years experience. We are confident that
you will be satisfied with your new system.
DEVI brings you…
An Invisible heating solution - A concealed heat source opens
up greater opportunities for decorating and furnishing.
Optimum comfort - DEVI brings you the luxury and comfort
of a warm floor as well as a pleasant room temperature.
Floor heating is the most comfortable type of heating
because it is based on the fact that warmth travels upwards;
pleasant warmth for your feet, body and head.
Low running costs – Thanks to the precise DEVI thermostat
and the placement of the heating elements right under the
floor surface the heat can be controlled optimally in order for
you to have the comfort you desire with minimal energy use.
Moreover electric floor heating is practically maintenance
free, in total keeping down the running costs.
A long lasting solution - We back-up our floor heating solu-
tions with a ten year guarantee on all our mats and cables,
and a two year warranty on our thermostats. Practically
speaking you can count on DEVI heating cables and mats
lasting as long as the house in which they are installed – and
that is without having to maintain them.
Hygiene - As DEVI produce floor heating systems, only very
gentle air is circulating, and the amount of travelling dust
particles is reduced considerably; a great relief for people
with allergies or asthma. There are also no dangerous fumes
such as carbon monoxide generated by the system.
Congratulations with…

3. Choose sensor combination
When installing the Devireg™ 535 you need to choose
the type of heating and thus which sensors should be
used. You have three options:
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 only the Floor sensor.
Total heating: Control of room temperature in living
rooms etc. Install the Floor sensor and choose both
Floor sensor and Room sensor.
No floor sensor: A floor sensor is not present, and
cannot be installed. Choose Room sensor. (Not
recommended).
Be aware that without a floor sensor, the temperature
control can be less accurate, and overheating of the
floor is of higher risk.
DEVI recommends that a floor sensor is always
installed.
When the thermostat is used to control a floor heating
element according to EN/IEC 60335-1 and
EN/IEC 60335-2-96, always use the floor sensor
and never set the temperature limit above 35°C.

DeviregTM 535 is an electronic timer temperature controller,
specially designed for floor heating systems.
The DeviregTM 535, once set, automatically adjusts the
heating to meet your comfort levels, regardless of changing
weather conditions by measuring the floor temperature and
combining it with the air temperature.
Even the programming of economy temperatures (i.e. lower-
ing of temperature during the night and when you are out
of the house) is very simple. Just tell the DeviregTM 535 your
daily rhythm and choose your program.
It also features a minimum floor temp. setting, eg. for
keeping your tile floors warm in summer as well.
