How can we change cards of EEV.... when not find same type. Like we change it from danfoce to sporlan

[@UATechnicalSolutions]

As far the valve specifications i.e
Volatge
Steps
Hertz
Milli amps
Are same as the old one you dont need to change the card
Secondly its not possible to install another type of card . As the rest of the cards in the chiller will not communicate with new type of card. If you are replacing the card is must be same as old
