  • Page 9 10.3 Compressor and heaters regulation in relation to ambient temperature It is possible to set an ambient temperature (parameter S08) under witch the heaters, if not previously ON, are switched ON. It is also possible to switch OFF the compressor if the ambient temperature falls below a determined temperature (parameter S10).
  • Page 10 10.4 How to disable the compressor It is possible to disable the compressor pressing key for 3 seconds. If the heaters are available, they are used to substitute the compressor. If the compressor is disabled, it remains in that state also after a power off. 10.5 Fan Fan operation mode can be set by F01 parameter: ...
  • Page 11 10.6 Anti legionella cycle The Anti-Legionella cycle is a procedure used to eliminate legionella bacteria; during the cycle the water temperature is increased to S12 set point for a period of time defined by parameter S16 (expressed in tens of minutes). Anti-legionella cycle can be activeted: At Power-On: if the parameter S14=y, the cycle is activated every time the instrument is switched on.
  • Page 12 ANTI-LEGIONELLA TIME OUT ALARM When the cycle starts, the controller activates the compressor or the heaters until the temperature reaches the set point value legionella. If the compressor can not be activated because an alarm block it, the heaters are switched on to substitute the compressor. When the anti legionella cycle starts, a maxim time to reach the set point starts counting;...
