Anyone performed the Dunham Bush NC25-4 controller (obsolete- originally made by Danfoss) upgrade to the Dunham Dush Director controller.
I have one on order thru DB, curious on ease of conversion and will it be worth the $$$$ spent
I couldn't find a similar controller that was not oem to operate this chiller
The NC25-4 stages all 3 screw compressors, 18 cond fans, loads/unloads the compressors from its software
Air cooled chiller it is on is a ACDX170B with 3 60 hp screw compressors
