The DeltaSol® Pool is a controller for heating a swimming pool by means of solar collectors and optimized operation of the filter system.

Backup heating of the swimming pool is varied according to solar power and pool demand, thus saving expensive energy.

The controller has many additional pool functions such as: additional filter runtime, maximum limitation of flow temperature and a flushing function.
