View Full Version : Maxkold controller

Hello all.

i was hoping that some of our UK members may be able to help with this.

I was after a service manual or parameter list for the pictured controller. It is marked as a CML Cool master control but has no model information. From what I've found on google it appears to be a Maxkold controller which I have never seen.

Problem is the controller is not accesile even to change the temp set point. I have tried several button combinations and so far have not been able to unlock it.

I found the Maxkold website but it will not open for some reason.


Thanks in advance

You are right, website will not open.
I think this one can be installed instead,
