Colour source 40

I have a coloursource 40. I have had no problems with it until now.

Recently i used the desk for the first time in a number of months. The desk was stored away in its pelecase and is not mechanically damaged. When i try to support a kino flo celeb 200 to the desk via a hard dmx it will set it up in the desk as per usual but the second channel, the temperature channel does nothing.  If i set up two channels as standard dimmers and address these to the same address as the celeb, the celeb will work perfectly. I know that i can get whatever i need through this setup, but i am just wondering why when i try use a celeb 2 channel personality or any 2 channel personality will the second channel not work??
