I want to put a programmable thermostat on my Lennox complete heat system. I have the HM30 system and not sure what thermostat I need (the cheaper or the most expensive.) I know it has something to do with auxilliary heat but I am sure if the complete heat system has auxilliary heat. Which thermostat do you recommend? Thanks.

Has anyone had an occurrence of a Laser 730 or 731 over firing?
The top of the heat chamber and the heat exchanger glow red on high when this occurs....
