the main reference room, which will be hea-
ted but not fitted with a temperature control.
If this is not the case, the setting AMBON "in-
fluence of the room" must be deactivated (re-
fer to QAA73 instructions).
- It must be fitted to the wall at approximately
1.5 m from the floor and away from any
source of heat (radiator, suns rays, lamps,
television, etc.) or cold.
- It must not be covered by a curtain or placed
inside furniture.
A standard 2 x 1.5 mm² cable must
!
be used. Maximum length of cable
: L = 50 m.

1.2 - Mounting the room sensor

- 4 -
The cable connecting the sensor to
!
the LMU management unit mut not
be laid in parallel or in the same
cableway as the 230 V electrical
cables (minimum distance of 30 cm
is recommended).
The best protection against distur-
bances is provided by a shielded
two-core cable.
In the respective buildings, the two
ends of the shielded cable must be
connected to a reference potential
(building ground).
- Fix the base to the wall using the screws.
- Replace the sensor facade on the top of the
base and close the sensor.
