Prior to each commissioning or as
required, the air inlet and outlet
grilles must be checked for clog-
ging.
The units operate via an integrated
hygrostat set to 60% relative hu-
midity (standard value for swim-
ming baths and indoor swimming
pools). The unit does not start at
room air conditions below 60%
relative humidity. If the relative
humidity is above 60%, the unit
automatically starts the dehumidi-
fication process.
The front housing panel can be
removed to make any changes to
the hygrostat setting.
The hygrostat is located next to
the evaporator below the com-
pressor housing.
Turning the control knob clockwise
reduces the humidity
, turning an-
ticlockwise
increases the humidity
.
An external hygrostat (accessory)
can be fitted if required.
Connection option, see under
“Electrical wiring diagram”.
In order to prevent compressor
damage, the units are provided
with reclosing protection, which
prevents immediate reconnection
of the compressor after disconnec-
tion
The compressor initially switches
on again after a delay of about 30
seconds!
Commissioning
NOTE
If the unit is switched on or
off via a main switch, all LEDs
successively show green and
the triangle red.
LED display
The units are provided with an
electronic control. The following
functions are controlled, monitored
and displayed:
■
Safety
■
Monitoring
■
On/off
The LED display is located on the
side of the unit.
The LED shows constant
„green“ when the unit is
connected to the supply.
The LED shows constant
„green“ when the com-
pressor is operating and the
unit is dehumidifying.
This LED has no function
for dehumidification.
Symbol legend
A „green“ flashing drop symbol
and a constant „green“ lightning
symbol indicate that the unit is
functioning, but has been switched
off by the condenser sensor (over-
nsor (over-
heating).
A constant „green“ lightning
symbol indicates that the supply is
connected to the unit.
Alternating „green“ and „red“
flashing LEDs indicate a unit fault
registered via the condenser sensor
(overheating).
If the condenser sensor registers
an excessive temperature, the
compressor is switched off and the
unit remains inoperational for 45
minutes.
After lapse of this time, the unit is
automatically switched on again.
After switching on again, the
„red“ triangle symbol no longer
flashes, the drop symbol continues
to flash.
The lightning symbol shows con-
stant „green“.

NOTE
Interruption of unit operation
for less than 6 minutes com-
pressor operating time will
force a restart lockout of about
4 minutes.
NOTE
If the relative humidity is
below 60%, the unit will not
start, even when the supply is
connected.
NOTE
The flashing drop symbol is
extinguished when the power
is switched off and on again.
