Your property has been installed with a DEVI electric
underfloor heating system. DEVI is Europe’s leading
under floor heating manufacturer, with over 45 years
experience. We have confidence 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.
with minimal energy use. With your DEVI system
there is no need for costly regular maintenance.
Durability - We provide you 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
Optimum comfort - DEVI brings you the luxury
and comfort of a warm floor as well as a pleasant
room temperature. A radiator system throws heat
up at head height which then travels further up to
the ceiling only to travel downwards and return as a
cold draft around your feet. DEVI underfloor heating
provides appropriately pleasant warmth for your feet,
body and head.
Economic running costs- The intelligent DEVI
produces only very
gentle air circulation, 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.

About the thermostat
Introduction
devireg™ 550 is an adaptive temperature controller, specially designed for floor heating systems.
It can, however, also be used for other heating
systems (e.g. with power heating units).
1
2
The devireg™ 550 will measure the radiant comfort from the floor combined with the comfort
from the air temperature in the room to offset
the outside weather condition. This means that
as soon as you have set your devireg™ 550 at
your desired comfort temperature, devireg 550
will then automatically adjust the heating to
meet your comfort levels, regardless of changing
weather conditions.
3
4
devireg™ 550 is also capable of detecting a sudden temperature drop in the room. Instead of
switching the heating on to immediately compensate, the devireg™ 550 uses the information
stored and then checks if this sudden drop of
5
2
temperature may be caused by for instance a
window that has been opened for 10 minutes.
Even the programming of economy temperatures (i.e. lowering of temperature during the night
and when you are at work) is very simple. You
do not have to calculate how much earlier the
heating should start in order to reach a specific
temperature at a specific time. Just tell the devireg™ 550 when you want the comfort temperature, and the devireg™ 550 will take care of the
rest. By identifying the rate of heat loss from the
room, the devireg™ 550 knows when to start heating in order to achieve the selected temperature
at exactly the right time.
devireg™ 550 - the thermostat that thinks!

About the thermostat
Switch timer function on/off
The timer function is used for automatic switching between periods with normal (comfort) temperature and periods with lowering of temperature (e.g. at night). When switched on, a timer
symbol (clock) is shown at the top of display.
- To switch the timer function off, press button.
- To switch the timer function on, press button
again.

Read more about how to set periods with lowering of temperature (e.g. at night) on page 12.
Clock ring
The markings on the clock ring indicate
periods with normal desired temperature
and periods with lowering of the temperature
(e.g. at night). The flashing point indicates
the actual time of day (every half hour).

To switch the thermostat on again, raise the temperature above +5°C (1 by scale). This is done by
turning the button clockwise .

the required temperature (5° to 35°), but
a scale from 1 to 10 (each whole number represents 5°C at floor temperature).

Set temperature
Manual thermostat (Constant temperature)
By switching off the timer function you can set
the thermostat so it will maintain a constant
temperature (see how to switch timer on/off on
page 5). The setting with constant temperature
can be used when 24 hour heating is required or
for constantly lowering the temperature when
going on holiday. An unbroken clock ring indicates constant temperature.

Fixed periods with lowering of temperature
By using the built-in timer you can set up fixed
periods for each day of the week where the temperature is lowered (e.g. at night and when you
are at work). This means automatic switching
between economy and comfort temperature.

12
Read more about how to set periods with lowering of temperature on page 15.
When the timer is on, it is indicated by a timer
symbol in the form of a clock (and a clock ring if
periods with lowering of temperature have been
selected).
The display shows the required
20:0 C
temperature of the room. Outside the
set heating periods (clear segments of
the dial) the system will maintain a
minimum temperature which is controlled according to the set-back level. This setting is programmed during configuration, (step 7, page 9).
e.g. If the requested temperature pr comfort level
is set to 20ºC, and the set back level (LO) is set
to -10ºC, the system will maintain a minimum
temperature of 10ºC. If the heating turns on
outside this period, please check set temperature
levels and configurations.”
Set temperature
the display shows temperature on a scale of 1-10
rather than degrees C. Recommended settings
in this situation are 5-6, which is 25-30°C (floor
temperature). Each unit represents 5ºC of floor
temperature.

temperature and the time you want economy
temperature. The thermostat will do the rest. You
