» Proper use
The en:key room set devices are intended solely for the purpose of controlling the room
temperature in closed, indoor rooms (e.g. residential and business rooms). The en:key
room set is not suitable for the operation of underfloor heating. Each room requires a
separate room sensor.
» Wireless radio systems and health
The Institute for Social-Ecological Research and Education (ECOLOG) has issued an
expert report confirming that the high-frequency emissions from wireless radio switches
and sensors with EnOcean technology are significantly lower than those from equivalent
conventional light switches. Other devices, such as wireless telephones, are higher than
those of wireless radio switches with EnOcean technology by a factor of 1500.
» Data protection
To regulate room temperature according to the user's requirements, en:key only uses
aggregate information. En:key processes this information in accordance with applicable
data protection laws. The room sensor can be reset to the factory settings at any time using
the “Restore factory settings” function. All information such as the learned heating time
profile and the radio partners is deleted permanently when factory settings are restored.

For a lasting bond, remove any dust and grease from the adhesive surfaces
on the wall mount and the wall.
Position the wall mount so that the bar can be easily accessed. Ensure a dis-
tance of at least 10 cm from other objects (door frames, electrical sockets,
cupboards, etc.).
Observe the alignment of the wall mount. The bar must be mounted on the
lower right side.

smooth side of the wall mount.
6b Remove the second protective film from the adhesive pad and press the wall
mount onto the marked position on the wall, making sure it is aligned correctly.
7b Press the “wall mount” onto the surface repeatedly and firmly.
The pressing force is more important than the duration.

» Mounting the valve controller
The valve controller is fastened directly onto radiator valves with an M30x1.5 DIN 13
connection (e.g. Heimeier, Honeywell, Cazzaniga, Oventrop - 1998 or later).
If several room sensors are removed from their rooms, identifying them with
a number makes it easier to find the correct room. The valve controller does
not need to be re-registered then.

Fastening the valve controller
The valve controller is fastened onto the radiator valve using an octagon nut (M30x1.5 DIN
13).
Item Designation Explanation
01 Radiator valve Controls the heat supply for the radiator
02 Octagon nut Fastens the valve controller to the radiator valve
03 Rotary knob Adjusts comfort temperature
04 Flange Connection to the radiator valve
Do not attach the flange and the octagon nut to the radiator valve in a tilted
position. If they are attached in a tilted position, the power supply from the
thermoelectric generator cannot be guaranteed.
The valve controller must not come into contact with the radiator when
mounted. If the valve controller and radiator come into contact with one
another, the power supply from the thermoelectric generator cannot be guar-
anteed.
