Description
The
AKO-16526A
advanced controller for cold room stores has a SELFDRIVE operating mode that automatically
controls (without parametrisation) the fans and adaptively minimises defrosts to optimise the performance of the
cold room store: maximising time in set point and minimising costs linked to energy consumption and wear of
components.
It has an output to regulate the electronic expansion valve. It can be configured so it can control superheating, as
well as adjust the cold in the store.
