FUNCTIONS
OF
HUMIDISTAT
By
reading
the
internal
sensor
of
temperature
and
humidity,
the
dew
point
will
be
calculated.
The
temperature
measured
from
the
internal
sensor
to
the
controller
will
be
compared
with
the
dew
point
(evaluated
at
the
last
moment
of
tAr)
added
to
the
parameters
odr
and
Hy:
•
If
Tr<Tint<Tr+odr
→
the
relay
is
activated
for
all
the
next
tAr
time.
•
If
Tr+odr<Tint<Tr+odr+Hy
→
The
relay
is
activated
for
the
value
in
%
of
the
detected
on
the
pump.
•
If
e
Tint>Tr+odr+Hy
→
the
relay
is
activated
for
all
the
nexyt
tAr
time.
The
parameters
tAr,
odr
and
Hy
are
set
in
the
factory
and
can
be
changed.

NOTES
FOR
INSTALLATION
Humidistat
The
relay
of
the
humidistat
must
be
connected
as
NC.
Two
cases
can
be
distinguished:
1.
dehumidification
is
not
required
(activation
of
double
set
‐
point)
when
the
relay
is
de
‐
energized,
the
water
is
sent
to
the
floor
plant
(according
to
set
‐
point)
2.
dehumidification
is
required
(deactivation
of
double
set
