That would be the old tri pole second wave form diode model.

Last produced in 1974.

is there a way to make the fan come on and off thermostat dictates?
Does your stat have the ability to control electric heat.
If so, set it that the stat controls fan.
If not, get a fan control and install it above the coil.

According to Winchester I am TOO involved.


But what the hey: You are both wrong about the sine wave inversion field density. The poly photon design makes it impossible for the stream to stay coherent enough to be tactile.

Replace the fan switch, the fan switch operates by tempature!
