Calibration of the difference between the cut-in and cut-
off temperature (hysteresis)
It may occasionally be necessary to adjust the different
between the cut-in and cut-off temperature (hysteresis).
EN
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 flashes
quickly
You are now in programming mode
Now use the SPEED +/- buttons to adjust the temperature
difference 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 difference 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 finished, pull the cord/cord mechanism once
more and the yellow indicator lamp stops flashing.
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 off, the fan returns to the
programmed function.
