Blinking Aprilaire 8366


Does anyone know what it means when all the LCD display characters blink on and off in unison on an Aprilaire 8366 (http://www.aprilaire.com/index.php?znfAction=ProductDetails&category#&sub=prog&item66)? It's a programmable Heat/Cool Multistage thermostat. New batteries don't change this behavior. Power is on to the furnace & condenser and neither of them indicate an error.

Well the instruction book only list for flashing data is when you are changing settings. I suggest removing the battery for say an hour or two and if that does not do it leave the battery out and try disconecting the power supply to the furnace low voltage circuit.

Get out of the house immediately. That thing is about to blow.
Go to a neighbor's house and call 911 and ask for the fire department's explosive containment operation.
