EKE 1P controllers

What do I do when the EKE 1P controller resets itself?

The reason could be that the EKE 1P controller has reset its settings after 32.000 hours of operation and a consequent power cut off.

It can happen with EKE 1P controller software (SW) 2.14 or older and if the controller is used with Application 2 as standalone driver (for example as valve driver with AK-CC55) or with Application 1 as extension module for AK-PC 572 but with User Defined valve. In both cases the recommendation is to update the controller to SW 2.15 or newer.

If EKE 1P is used as extension module for AK-PC 572 with a standard Danfoss valve, no further action is needed.
