Abstract

An adjusting method to adjust dispensing of at least one chemical product in a circulation hydraulic circuit having one or more branches (230, 240, 250), wherein at least one dispensing device (D1, D2, D3) is configured to dispense, when activated, at least one respective chemical product in the circulation hydraulic circuit, comprising the step of:

detecting one or more liquid flow rates in one or more respective branches (230, 240, 250) of the circulation hydraulic circuit through one or more respective flow rate sensor devices (F1, F2, F3);wherein:if a regular condition occurs wherein said one or more liquid flow rates detected in said one or more respective branches (230, 240, 250) of the circulation hydraulic circuit are not lower or are higher than respective flow rate threshold values, an activation of said at least one dispensing device (D1, D2, D3) is enabled, andif an error condition occurs that is caused by at least one of said one or more liquid flow rates detected in at least one respective branch of said one or more respective branches (230, 240, 250) of the circulation hydraulic circuit that is lower or is not higher than a respective flow rate threshold value, an activation of said at least one dispensing device (D1, D2, D3) is inhibited for a time duration equal to a restoration time (T) wherein said at least one detected liquid flow rate causing said error condition is restored to a value not lower or a value higher than said respective flow rate threshold value plus an additional inhibition time (T1; T2; T3) associated to at least one flow rate sensor device (F1, F2, F3).
