Risk of death from carbon monoxide
when operating with air-ventilated
fireplaces.
When operating with air-
ventilated fireplaces and in
"air extraction"
installation position
, a sufficient fresh air
supply must be ensured. The maximum
permitted pressure difference per living unit is
4 Pa. The consent of a professional chimney
sweep is needed in all cases.
Danger of electric shock from
operating with the unit not fully
mounted.
Before taking off the
electronics cover, shut down all supply
circuits (switch off mains fuse), secure
against being accidentally switched back on
and position a visible warning sign. Only
operate the fan when it is completely
installed. Do not commission a damaged unit.
Danger if the relevant regulations for
electrical installations are not
observed.
Before installing the electrics, shut down
all supply circuits, deactivate the mains fuse
and secure it so it cannot be switched back
on. Attach a warning sign in a clearly visible
place.
Be sure to observe the relevant regula-
tions for electrical installation; e.g.
EN 50110-1, in Germany this is particularly
VDE 0100, with the corresponding parts.
A mains isolation device with contact
openings of at least 3 mm at each pole is
mandatory.
Only connect unit to a permanently wired
electrical installation with NYM-O / NYM-J,
2 x 1.5 mm² or 3x 1.5 mm².
The units may only be operated using the
voltage and frequency shown on the rating
plate.
The degree of protection stated on the
rating plate is only guaranteed if installation is
undertaken correctly and if the connection
cable is correctly guided through the cable
grommet. The grommet must tightly seal the
cable sheathing.
Unit may be energized even when at a
standstill and may be switched on
automatically by sensors, such as for time
delay or humidity etc. Maintenance and fault
finding only permissible when carried out by
trained specialists.
Exercise caution when handling
packaging materials.
Observe applicable safety and accident
prevention requirements.
Store packaging material out of the reach
of children.
Operation / Function
5.
5.1 ECA piano STANDARD
Speed controllable. On/off with light switch or
separate switch (both to be supplied by the
customer). Fan switches on/off immediately
when the switch is operated.
5.2 ECA piano TC with adjustable
overrun time
not speed controllable. On/off with light switch
or separate switch (both to be supplied by the
customer). Fan switches off immediately
when the overrun time expires after the
switch has been operated.
Overrun time: approx. 3 … 25 min.,
(factory setting approx. 6 min.)
5.3 ECA piano H with humidity control
and adjustable overrun time
Not speed controllable. Different functions
depending on the connection version.
Version 1:
The fan switches on automatically
when the relative ambient humidity in the
area of the fan exceeds the pre-defined
switching point. The fan is switched off when
the humidity level drops below the switching
point threshold and once the defined overrun
time has expired. The fan can also be
deactivated with the optional “S1” switch.
