Specifications

In order to get the best possible result when
using the devireg
™
540/550, the thermostat
should be installed in the wall, following a few
basic rules:
Installation height, typically between
80-150 cm.
On a wall NOT facing the outside
On a wall where it will NOT be subjected to
direct sunlight
Away from windows/doors that will open
occasionally
It must not be covered by curtains, towels etc.
The devireg
™
540/550 should not be installed
in small rooms with insuffi cient ventilation, such
as bathrooms. In these instances, place the
thermostat just outside the room (only use the
fl oor sensor - FS). The thermostat must not be
placed close to areas with a high risk of water
stains, e.g. close to running water, toilets etc.
