Chlorinator - Clearwater QC270 -schematic!!

Hi can any one supply a schematic for the circuit board in this unit.

I have mannaged to identify that R2 value 22K, has gone open circuit, I guess the other one in series is R1, that checks out ok.

I have done a little work on trying to draw out the circuit, but as you all will appreciate its soooo painfull.

I would realy appreciate some feedback even if no one has a schematic on the basic operation of how the board is operating...

Cheers
