Functional description
Heat transfer / thermostat
The Celsius is tted with an integrated electronic thermostat.
This starts the fan when the temperature exceeds the preset
value. The fan can easily be adjusted to start between 16 and
30°C. The factory setting for the starting point is approx. 26°C.
The starting point is adjusted using the plus and minus keys
(TEMP) on the control panel.
The start value is indicated by the LED lamps on the thermo-
meter scale. When the thermostat activates the fan, the
yellow indicator lamp lights up.
Before the starting point is adjusted, the fan must be
connected for at least 30 minutes. This is in order for the
fan’s electrics to reach operating temperature.
RPM settings
The fan speed can be set to anything from 50% up to maxi-
mum speed. The plus and minus keys (SPEED) on the control
panel are used to set the preferred speed.
The speed is indicated by a column of LED lamps labelled
with a scale from 1 to 8. If you adjust the speed down to zero
(no lamp is lit), the fan stops.
Constant operation
The Celsius also has a constant operation function.
The fan runs continuously at a preset speed.
The yellow indicator lamp does not light up during constant
operation. It is rst lit when the thermostat is activated, the
fan then reaches the speed set for heat transfer.
Pause function
The pause function means that the fan stops (whichever
mode it is in) and remains inactive for one hour. The pause
function is activated by pulling the power cord; after one
hour the fan resumes operation. During this time the yellow
indicator lamp ashes. The pause function can be cancelled
by pulling the cord a second time.
EN

Advanced functions
Activation of constant operation
• Pull the power switch mechanism once
- the yellow indicator lamp ashes.
• Set the desired speed using the plus and minus keys (SPEED).
• Pull the power switch mechanism
– yellow indicator lamp stops ashing.
The fan now runs constantly even when the fan's thermostat
function is not activated. This means that the fan can operate
at two individual speeds at constant operation or thermostat
operation if desired.
Switching o constant operation
• Pull the power switch mechanism once
- the yellow indicator lamp ashes.
• Press the minus key (SPEED) until no green indicator lamps
are lit – the fan stops.
• Pull the power switch mechanism
– yellow indicator lamp stops ashing.
Calibration of thermostat
There may occasionally be a need to calibrate the thermostat.
The fan must be connected for at least 30 minutes before-
hand in order for the electronics to reach their operating
temperature.
• Press in one of the plus or minus (TEMP) buttons.
• Then pull the power switch mechanism once
• Release the button – the yellow indicator lamp ashes
slowly
You are now in programming mode
Use the TEMP +/- buttons to adjust the temperature to the
room/desired level.
The temperature is indicated by one or two indicator lamps.
Even degrees are displayed with one lamp on the temperature
scale and uneven degrees with two lamps, one above and
one below the desired level. Pull the power switch mechanism
again and the yellow indicator lamp stops ashing. Calibration
is now complete.
10

Calibration of the dierence between the cut-in and cut-
o temperature (hysteresis)
It may occasionally be necessary to adjust the dierent
between the cut-in and cut-o temperature (hysteresis).
The default value is 1.5°C.
• Press in one of the plus or minus (SPEED) buttons.
• Then pull the power switch mechanism once
• Release the button – the yellow indicator lamp ashes
quickly
You are now in programming mode
Now use the SPEED +/- buttons to adjust the temperature
dierence to the desired level.
The temperature is indicated by one or two indicator lamps.
Whole degrees are displayed with one lamp on the speed
scale and half degrees with two lamps, one above and one
below the desired level. Each step adjusts the hysteresis by
half a degree.
For example, if a dierence of 2.5°C is desired, the tempera-
ture is increased until the indicator lamp 2 and 3 is lit on the
speed scale.
The lowest hysteresis is 0.5°C as no lamps are lit.
When you have nished, pull the cord/cord mechanism once
more and the yellow indicator lamp stops ashing.
Calibration of hysteresis is now complete.
Forcing with ignition wire (control phase SL)
The Celsius also has a forcing function. To gain access to this,
the fan must be connected with ignition wire (control phase)
to SL on the plinth.
Function:
Power supplied (current to SL) via an extern switch causes
the fan to run at max. speed independently of other active
functions.
When the switch is turned o, the fan returns to the
programmed function.
EN
11

LED indicators
LED - what is the fan doing?
The fan uses a yellow indicator lamp to indicate heat transfer
– the thermostat is switched on.
The yellow indicator lamp also has three dierent ashing
speeds.
• Slowly – Calibrating the thermostat
• Medium – The pause function is activated
• Fast – adjustment of the dierence between the cut-in
and cut-o temperature (hysteresis).
If the constant operation function is used, no lamp lights up.

Maintenance
The Fresh Celsius is designed to work eciently for many
years.
The fan needs to be cleaned at regular intervals if it is
to function properly. These intervals are determined by
duration of fan operation and air quality.
Clean the fan at least twice a year, or as required.
Disconnect the power supply to the fan by pushing the multi-
pole switch up to position O - OFF.
The fan is tted with a removable impeller. Press in the centre
using your thumb, grip the fan wings and pull the impeller
o. The fan's "swing out" function is also useful, as it provides
easy access to the duct. Press the motor ring’s quick-release
catch and swing out the motor/impeller.
Clean the duct/pipe if there is any dirt present inside. Failure
to do this may result in a risk of impaired capacity.
OFF
EN
13

When cleaning the fan, pay particular attention to the fan
wings if these are dirty. There is otherwise a risk of imbal-
ance and hence increased noise and a reduced life span
for the motor.
The easiest way to clean the impeller is using a brush and a
weakly diluted washing up liquid.
Dry o the impeller after cleaning.
Clean the fan cover with a polishing cloth moistened with
water and possibly a mild detergent.
NB! Never use solvents or similar products on any part of
the fan, as there is a risk of them damaging the fan's plastic
components!
Never submerge the fan in water, as there is a risk that this
could seriously damage the fan.
After cleaning, swing the motor mount ring back into posi-
tion and lock it by securing the snap-in catch. Remount the
impeller, press in until it clicks into place. Switch the multi-
pole switch back on by moving it down to position 1 - ON.
If maintenance of the fan is not performed as specied
above, the product guarantee will be void.
