Kool o matic fan thermostat

[Stephen]

I have a 90wb that has a Kool o Matic fan in the galley. The owners manual says
it is controlled by a thermostat in the kitchen but the only one near there is
on the opposite side wall between the couch and the table.

There is what looks like a ceiling fan switch under the cabinets but it doesn't
turn anything on. Is that it and if so is could I get a wiring schematic so I
could test it?
