Hello,
My house was built in '05 and I have an Ultra V Tech 80 Natural Gas Furnace. I have a digital thermostat controlling it which has always been there. My problem is that I can't get the heat to kick on when it's in Auto. I can use the thermostat to just turn the fan on so I guess the fan works. I'm really bad at this stuff. I found another guy that posted in '08 that he had the same problem but there wasn't a reply. I'll post his too. Hopefully someone can help me out. I'd really appreciate it. Thanks! :)

"Just moved into a rental house on a temporary basis and ran into a problem.
The house has Ultra V Tech 80 furnace which will not start. There is no heat and the blower will not blow when on auto.
I opened it up and checked the LED. It is blinking non-stop which does not match any of the codes on the sticker on the door.
Anyone have any ideas or at least a link to the owners manual?
I have already tried resetting breakers, changing filters and cleaning the flame sensor."
