Overflow pools are often amongst the most beautiful pools available. However, they have one major drawback – the energy losses resulting from the overflow channel.

Now there is a solution to that problem: AS Control Plus.

By installing a Besgo 3-way valve and an AS Control Plus controller, one can determine whether the pool water flows via the overflow channel or via the main drain, depending on the ambient air temperature.

In economy-mode – direct return via the main drain – the water no longer flows through the overflow channel. In this way energy losses due to evaporation can be significantly reduced.

Economy mode is best suited to periods of cold weather or during a pool heat-up period.

Saving can reach at least up to 10’000kW over the course of a full season with adequate investment.
