Management of Smoke Fan Operation in Aqua Stoves

Management of Smoke Fan Operation in Aqua Stoves

Only Aqua stoves allow changing the operating mode of the smoke fan, choosing between regulation by seconds (SEC) or by revolutions per minute (RPM) via encoder.

To ensure stable, precise, and efficient operation of the smoke fan, it is always recommended to use the RPM mode, which provides more accurate combustion control.

The parameter that determines this configuration is P25, section "Combustion Fan", in the System menu:

• P25 = 0 → operation in SECONDS [SEC]
• P25 = 1 → operation in RPM with encoder (default setting)
• P25 = 2 → should not be set

Attention – for MB250 control units:

The reference parameter is P27, section "Smoke Fan", in the System menu:

• P27 = 0 → operation in SEC
• P27 = 1 → operation in RPM with encoder (default setting)
• P27 = 2 → should not be set
