Electrical connections to be made by the installer.
Each thermal-ventilating unit requires a switch (IL) on the power
supply line with a distance of at least 3 mm between the opening
contacts, and a suitable safety fuse (F).
If more than one louvre is connected to an individual controller,
eliminate the transformer (T) and wire everything as indicated in the
diagram of
figure
6. In this case, provide a 24 V power supply line by
sizing the transformer (TL) according to the number of expected
louvres. The consumption of every single servomotor is 5 VA.
The EDMFA louvres may be connected in parallel to 1 unique
controller up to a maximum of 10.
O
PERATION
The louvre is operated by the control panel that contains the rotary
potentiometer that regulates the opening of the louvre in proportional
mode.
When setting the control to 100%, the position of the louvre is that of
total outdoor air inlet. When setting the control to 0%, the position of
the louvre is that of total ambient air recycle.
The scale on the control panel indicates the percentage of the fresh
air.
C
LEANING OF THE AIR FILTER
At regular intervals, clean the filter on the fresh air line and the filter
on the recycled air line.
The servomotor is always located on the left-hand side.
