The
sensors
necessary
to
activate
the
controller
and
ensure
its
correct
operation
are
the
supply
air
temperature
sensor
and
the
air
intake
temperature
sensor,
the
latter
of
which
also
measures
the
outside
temperature
(weather
sensor).
Use only sensors of the
NTC
10K
type.
Sensor cables may be additionally extended, using cables with a cross-section of ≥ 0.5mm
2
,
,
total length of cables
≤ 15m.
CAUTION!
The
sensors
must
be
installed
correctly
and
firmly,
and
protected
against
loosening
on
ventilation
ducts,
according
to
the
guidelines
of
the
unit's
manufacturer.
The
sensors
must
not
be
flooded
with
water
or
oils.
Sensor
cables
should
be
separated
from
power
supply
lines
and
heat
sources
(incorrect
temperature
indication).
The
minimum
distance
between
such
cables
≥
40cm.
The
sensors
must
be
connected
to
the
controller,
according
to
the
wiring
diagram.
To check the sensors, measure their resistance at a given temperature. The table below shows the nominal resistance values
provided by the manufacturer.

Connecting
the
room
panel
The ecoSTER TOUCH room panels can be connected to the controller module socket. The panels function as:
•
a room thermostat,
•
a control panel for the controller,
•
alarm signalisation.
CAUTION!
Only
1
room
panel
(control
panel
+
room
panel)
can
be
connected
directly
to
the
+5V
power
supply
terminal
of
the
ecoVENT
module
socket.
All
other
panels
(2-32,
31
pcs.)
must
by
supplied
from
an
external
power
source
of
+12VDC,
