Description
The AKO-16526A / 16526AN 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 perfor-
mance 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.
The AKO-16526AN controller incorporates a NBIoT communication module that allows it to send operation data
to akonet.cloud autonomously.
