I prefer to set the heat manually, rather than use the program.

the analog unit uses just two wires for heat. red - white. there is a heat anticipator setting that must match the burner current. check your programmable specs and follow instructions.

Without a model number, it's hard to help Ya out, but most manuals are here: http://www.honeywell.com.au/business/acs/acp/ecc/ec/residential/identify.html

Solution #2 as above worked (thank you very much!) to get to the programming mode, but on mine keeping Function #13 on the default setting of "0" maintained the AIR. Toggling the Temp button to "1" changed the system to conventional on/off at the programmed times.

Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.
Hope that helps...
