Kool o matic fan thermostat

[Don Bradner]

White is the supply voltage, in this case used for both heating and cooling
(fan), so jumpered to Rh and Rc on a standard thermostat.

Brown is heat, W on a standard thermostat.

Green is Fan, G on a standard thermostat.

I used the Hunter 42999B, which is around $20 from Wal-Mart. See
http://www.hunterfan.com/product_detail.aspx?id=7414 This is a universal
thermostat that doesn't care about voltages on Rh or Rc. Millivolts or 24-volts,
it doesn't care. Uses a battery to control the display.
