I tested the G3-16200 with the 7-slot external filter wheel and found a few issues
1) the displayed cooling power stays unchanged at about 42% but the temperature changes to the commanded value correctly.
2) Fan On/Off causes the alert and error in the log:
miccd_fan error: Unknown error -1.
3) The external filter wheel has 7 slots but there are only 5 slots in the driver.
I want to update. I installed the newer driver from INDI Github and the problems mentioned above were solved. After the end of the exposure, I got this error:
