Well... If you're working off the Chassis Service manual, that is the correct book. I've run some maintenence on my Comfortron out of this manual. All the stuff for the Toronado is in the very back of the book, after the yellow indexes. The 94 & 96 series... Anything specific to the Toronado is in these pages. The information on the Comfortron begins on page 1EB-1. As far as I can tell, all the information you should need on its troubleshooting and maintenence is located within these pages. Minus part numbers.
The control mechanism you describe sounds like the Comfortron, you should have a wheel with temperature numbers marked in it to the left of your levers, yes? IIRC, the wheel to the right is for cruise control. (though I may have those two reversed)
Just to be clear, we are talking about this manual here:
