About the thermostat
Introduction
Devireg™ 550 is an adaptive temperature control-
ler, specially designed for floor heating systems.
It can, however, also be used for other heating
systems (e.g. with power heating units).
The Devireg™ 550 will measure the radiant com-
fort 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.
Devireg™ 550 is also capable of detecting a sud-
den temperature drop in the room. Instead of
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 tempera-
tures (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 ear-
lier 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!
