Notes
Engineering
Powering the sensor requires a transformer for safety extra low-voltage (SELV) with sepa-
rate windings for 100 % duty. When sizing and protecting the transformer, comply with all lo-
cal safety regulations.
When sizing the transformer, determine the power consumption of the room sensor.
For correct wiring, see the datasheets of the devices with which the sensor is used.
Observe permissible line lengths.
Note that when routing cables, the longer the cables run side by side and the smaller the dis-
tance between them, the greater the electrical interference. Shielded cables must be used in
environments with EMC problems.
Twisted pair cables are required for the secondary supply lines and the signal lines.
Mounting
Interior mounting (without AQF3100)
Inside wall (not on outside wall!) of the room to be air conditioned; not in recesses, behind
curtains, above or close to heat sources or shelves; not on walls behind which a chimney is
located.
The sensor must not be exposed to direct solar radiation.
Install the sensor in the occupied space about 1.5 m above the floor and at least 50 cm from
the next wall.
CAUTION!
● The degree of protection IP65 is not ensured if the seal between the base and cover is
removed.
● The sensing elements inside the measuring tip are sensitive to impact. Avoid any impact
on mounting.
Without using the AQF3100 outdoor mounting kit, the sensor must not be mounted with the
measuring tip pointing upward.
Mounting instructions are printed on the package.
Outdoor mounting (with AQF3100)
Exterior wall, preferably on the North or Northwestern side of the building; if possible in the
middle of the wall, at least 2.5 m above the ground.
Not above or below windows, above doors and ventilation shafts, below balconies or eaves.
The sensor with AQF3100 must be mounted in a vertical position (radiation shield at the top).
Mounting Instructions are enclosed with the AQF3100.
NOTICE! When using the AQF3100 outdoor mounting kit, the sensor’s cable entry hole must
be closed off with the grommet and the prepared M16 cable entry on the opposite side
knocked out.
