Hi Guys!
I have poured over various Danfoss PDF's online and cannot find the answer to my Query!
I am looking to replace a suspect ICM 25 Module. Only when I look at Table 2 there are 3 options.

ICM 25-A
ICM 25-A33
ICM -B
I am struggling to find out what these derivatives mean.
Can anyone Help Please?
