Hi Oldtimer,

Are the controllers on the network? or are they set in local. Sometimes if you have a network initiated defrost and the controller has settings for the local mode set into it, it can cause a double defrost scenario. Rdm controllers can have this issue also :(

Double defrost is mentioned on this thread.
