Operating sequence
The units can be used in
the respective modes for air
heating and air circulation
purposes.
The units can be operated on
one
heating and
one
fan setting. They
have a 3-stage operating switch
with the functions: Heat (I) / Off
(0) / Fan (II).
In setting I (Heat), the heating
resistor and air circulating fan are
switched on and warm air is blown
out.
The unit is equipped with an
integrated thermostat to ensure
that the room temperature is
constant.
Once the selected temperature
has been reached, the thermostat
stops the heating operation.
If the room temperature falls
below the selected temperature,
the thermostat starts up
the heating operation again.
The integrated temperature
limiter switches off the unit if
the temperature is excessively
high and switches it on again
automatically after it has cooled
down.
In setting II (Fan), only the air
circulating fan is switched on and
the unit can only be used for air
circulation.
After switching off the units via
the operating switch or the room
thermostats, the supply air fan
runs to cool the heating resistors
for a certain time and then
switches off automatically.
Commissioning
Heating
The unit operates in a fully
automatic manner subject
to the temperature that is set
on the thermostat.
1. Set the desired
room temperature
on the thermostat.
2. Move the operating
switch to the “I”
(Heating) position.
Fan
Only the supply air fan operates in
this setting. Thermostatic regulation
and heating operation are not
possible in this operating mode.
1. Move the operating
switch to the “II” (Fan)
position.
One person, who has been
adequately trained in the handling
of the units, should be tasked with
the operation and monitoring
of the units.
The units must be in the intended
horizontal position on their
supports at all times during
operation.
1. Check that the mains power supply
matches the operating voltage
of the unit 230V/1~/50 Hz
2. Move the operating
switch to the “0”
position.
3. Connect the unit's power
plug to a properly
installed mains
socket.
NOTE
The electrical connection for the
units must be made at a separate
feed point with a residual current
device in accordance with VDE
0100, Section 55.
NOTE
For optimum operation
the units should not be
operated above an ambient
temperature of 25 °C.
CAUTION
Extensions to the connection
cable must only be conducted
by authorised specialist
electricians, taking into
consideration the unit capacity,
cable length and local use.
CAUTION
All cable extensions must only
be used in fully un-reeled
or reeled off condition.
