This would apply to most cooled ccd's in range.
First of all you need to plan your workflow for usage
1. connect your camera to usb port
2. startup your imaging software
3. select your cooling controls, and set a temp of say 5 degrees.
4. then power the 12 volts into camera Dont power up this till you have control of camera thru the software.
5. wait about 5 mins for temp to reach setpoint, then advance setting to 0 degrees. wait 5 mins more.
6. set temp to -5 degrees, wait till temp is achieved, give another min or so then advance it to -10 degrees. wait another 5 mins or so.
7. do some test shots to confirm no frosting (or visibly check sensor for evidence of frost)
after this you can if you can reach it goto -20 degrees.
If at any time frosting occurs backoff 5 degrees and wait for it to sublime off sensor.
It will do so.
Tonight's test could only reach -15 due to ambient being 12 degrees C
The second night shooting I had frost occur, first night was fine but was running only 0 degrees
I opened up the side port and installed the AUX plug,
My testing then had frost form if I sent it to -10 from a high ambient about 20 degrees
Tonight using the above steps I had no frosting at all, not even a hint. down to -15
