Codes
- air19Error codeSensor outdoor air
- C4Error codeMalfunction / dirty filter alert (LED SAI Flash) Output voltage at malfunction / alert = 5 V
- FAN12Error codeSpeed of the exhaust fan
- FAN22Error codeSpeed of the supply fan
- LOW150Error codeThis error must be resolved in order to carry out a system test. Otherwise errors of the preheater or bypass cannot be resolved! Possible causes: ■ HIGH SETTING set lower than 160 m3/h ■ Air volume of valves not set correctly (valves too tight) ■ Air ducts have too much resistance ■ Outdoor air grille blocked ■ ALTITUDE entered incorrectly ■ Filters are dirty ■ Heat exchanger is frozen
