Fan motors:
SLN 40 = Motor M2
SLN 60 = Motor M2 and M3
SLN 80 = Motor M2 M3 and M4
Constant ventilation:
If constant air circulation is re-
quired, i.e. independent of de-
humidification, a jumper can be
connected between terminals
25
and 26
.
The fan or fans then operate with-
out any control and monitoring in
a continuous mode.
External hygrostat:
Recommended for frequent hu-
midity variation is the installation
of an external hygrostat which is
available as an accessory.
Disconnect the integrated hygro-
stat at terminals
21 and 22
.
Install the external hygrostat at a
suitable location in the room to
be dehumidified and connect to
terminals
21 and 22
.
The output voltage on terminals
21 and 22
is
12V
.
NOTE
Only authorised specialists
may install and carry out
maintenance work on the
units!

NOTE
A disconnector switch should
be installed in the supply con-
nection at a suitable and easily
accessible location.
ATTENTION
Prior to carrying out mainte-
nance or repairs, the unit must
always be disconnected from
the supply.
