ELECTRICAL HAZARD!
The electrical installation and (dis)assembly of the MATRIX control panel may
only be carried out by qualified electricians in compliance with the given oper-
ation manual and current VDE regulations.
•
Before drilling, ensure that the drilling area is free from electrical cables and
pipes.
•
Only indoor mounting of the MATRIX control panel is allowed.
•
Do not connect the MATRIX control panel to an external voltage.
NOTE!
The installation site of the MATRIX control panel or room temperature sensor
is crucial for the precise measurement of room temperature.
Therefore the MATRIX control panels or sensors must:
– not be fitted next to doors, windows, passages etc., since intense movement
of air can cause incorrect measurements,
– not be fitted on hot or cold walls (e.g. chimney, outside wall),
as wall temperature can cause incorrect measurements.
– not be fitted behind curtains or net curtains, since the insulating layers of air
can cause incorrect measurements,
– not be fitted adjacent to unit discharge grilles as discharge temperature can
cause incorrect measurements
– not be fitted below cold surfaces like windows, since descending cold air
flow can cause incorrect measurements.
