APT 'Cooling Aid' issue ??

[Skipper Billy]

I use APT for capture and filter wheel etc.

This winter more often than not when I turn on the 'cooling aid' it starts to drop the camera temp then reports that it cannot achieve the desired temperature in the required time' or something along those lines.

I am not asking for anything extreme - ambient temp circa +2º - and requesting -10º in 2º steps.

If I just turn on the APT cooler it achieves -10º in about 40 seconds and if I control the camera with Maxim DL it hits minus 10º in about 40 seconds so I dont think its the camera.

Any ideas ???

I am using APT v3.2 and an Atik 460EX
