system for electrical control of hot-water
and heating systems, and functions as a
trigger for electro-thermal actuators or
other electrical devices
It may be used only in dry and closed
rooms. Relative air humidity in the room
may not exceed 95%.
This thermostat may be installed only
by qualified electricians in accordance
with these fitting instructions. These
professionals are responsible for
observing existing standards and
regulations.
Installation must always be implemented
while device is disconnected from
the mains, with due regard for safety
regulations.
The thermostat must be positioned so
that it is not covered by net curtains,
furniture or other objects. The control unit
must not be installed in the immediate
vicinity of heat sources either (e.g. lights,
