1.1 - Recommendations
- The room sensor QAA73 must not be fitted in
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
so
urce of heat (radiator, suns rays, lamps,
television, etc.) or cold.
- It must not be covered by a curtain or placed
i
nside furniture.
!
A standard 2 x 1.5 mm² cable must
be used. Maximum length of cable
: L = 50 m.
!
The cable connecting the sensor to
the LMU management unit mut not
b
e 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
tw
o-core cable.
In the respective buil
dings, the two
ends of the shielded cable must be
conne
cted to a reference potential
(building ground).
1.2 - Mounting the room sensor
- Open the sensor from underneath and move
the base from the facade.
- Connect the cable to the 2-pin connector
waiting behind the base of the QAA.
- Fix the base to the wall using the screws.
- Replace the sensor facade on the top of the
base and close the sensor.
