About the thermostat
Introduction
1
devireg™ 550 is an adaptive temperature control-
ler, specially designed for l oor heating systems.
It can, however, also be used for other heating
systems (e.g. with power heating units).
2
h e devireg™ 550 will measure the radiant com-
fort from the l oor combined with the comfort
from the air temperature in the room to of set
the outside weather condition. h is means that
3
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
4
weather conditions.
devireg™ 550 is also capable of detecting a sud-
den temperature drop in the room. Instead of
5
switching the heating on to immediately com-
pensate, the devireg™ 550 uses the information
stored and then checks if this sudden drop of
2
temperature may be caused by for instance a
window that has been opened for 10 minutes.
Even the programming of economy temperatu-
res (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 specii c
temperature at a specii c time. Just tell the devi-
reg™ 550 when you want the comfort tempera-
ture, 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 hea-
ting in order to achieve the selected temperature
at exactly the right time.
devireg™ 550 - the thermostat that thinks!
