Where can I find what certain error codes mean for a Comfort Furnace - Infrared Portable 1500UV-P?

When turning on a Comfort Furnace CF1500UV-P, the display flashed three times, then flashes 2.00 for about one second, then shows the temperature the heater is set at, but it never turns on. We even tried raising the temp to well above room temp to see if it would kick on but no luck. I've looked on the internet, but can't find anything to tell me what these codes mean.
