ADVANCED FUNCTIONSCalibration of the difference between the cut-inand cut-off temperature (hysteresis)It may occasionally be necessary to adjust the differencebetween the cut-in and cut-off temperature(hysteresis).The default value is 2°C.• Press in one of the plus or minus (SPEED) buttons.• Then pull the power switch mechanism quickly.• Release the button - the yellow indicator lampflashes quickly.ENYou are now in programming modeNow use the SPEED +/- buttons to adjust the temperaturedifference to the desired level.The temperature is indicated by one or two LEDlamps. Even degrees are displayed with one lamp onthe temperature scale and uneven degrees with twolamps, one above and one below the desired level.Each step adjusts the hysteresis by half a degree.E.g. if a difference of 4°C is required, the temperatureis increased by 8 steps to 24°C.When you have finished, pull the cord/cord mechanismonce more and the yellow LED stops flashing.Calibration of hysteresis is now complete.Forcing with ignition wire (control phase SL)The Celsius also has a forcing function. To gain accessto this, the fan must be connected with ignitionwire (control phase) to SL on the plinth.Function:Power supplied (current to SL) via an external switchcauses the fan to run at max. speed independentlyof other active functions.When the switch is turned off, the fan returns to theprogrammed function.13
