If power control is DC-201 then code for QHY9 camera should work on QHY8L for temperature control and readout. Take a look at Giampiero's code in this source. (Note: this code could be an old version)
If you send Giampiero email with your driver, he will add it to QHYimager which can do the debayer. And, he can share with you his debayer which already exists.
