installation height = 1.5 m
Electrocution through hazardous voltage will lead to death or serious injury.
The electrical installation and (dis)assembly of the FläktGroup CET.ACEC com-
pact controller may only be carried out by qualified electricians in compliance with
this operation manual and current VDE regulations.
• Before drilling, ensure that the drilling area is free from electrical cables and pipes.
• Mount the FläktGroup CET.ACEC compact controller only in closed rooms.
NOTICE!
The installation site of the CET.ACEC compact controller or the room tempera-
ture sensor is crucial for the precise control of room temperature.
Therefore do not mount the CET.ACEC compact controller or the sensor
– next to doors, windows, passages etc., since intense movement of air can
cause incorrect measurements,
– on hot or cold walls (e.g. chimney, outside wall), since the wall temperature can
cause incorrect measurements,
– behind curtains or net curtains, since the insulating layers of air can cause incor-
rect measurements,
– adjacent to the unit's discharge grilles, since the discharge temperature can
cause incorrect measurements
– below cold surfaces like windows, since descending cold air flow can cause
incorrect measurements.
NOTICE!
If a FläktGroup fan-coil unit has a heating or cooling change-over function, the
mounting location of the inlet-water temperature sensor is of decisive signifi-
cance for the accuracy of the automatic switch-over.
• Therefore, mount the flow sensor on the piping at a position where the current
water temperature can be best recorded. Pay attention that the sensor is not
mounted at a position where the water flow can be blocked, e.g. by a valve.
