5.5 INSTRUCTIONS FOR INSTALLATION

The position of the control panel shall be selected based
on a proper location of the room sensor, embedded
in the panel; however at 1.5 m from the floor and far
from any heat/cold source (different heaters, windows,
etc). The control panel can be fixed to the wall hanging
by provided slots or recessed in the wall by means of
proper box. The wall surface shall be flat to avoid the
panel box deformation once fixed and the consequent
difficulty in coupling the cover.
After the box is fixed, remove the cable terminal From
the slot and do the cables connection; then put the
terminal back into the slot.
The communication protocol allows of 50 m maximum
cable length and Ohm resistance of each cable shall
not exceed 5 Ohm.
In case of proximity to strong electromagnetic field, it
is recommended to use shielded cable.
