Check with Mark, It is probable in there some where as an undocumented
feature, I know the 'MOON MAN' thing is in there.
I tried LH's temperature controller as a room thermostat once by connecting
it up to a infrared electric heater thru an isolated SCR switch.
I figured, why just keep the Tbolt constant when you can keep the whole room
Because it will control a Heater and/or a Fan the hair-dryer thing should

Maybe a LH controlled hair-dryer to burn off some snow?
