I mean no disrespect, nor do I want to argue, but if a thermostat doesn't have the copper colored button on the bottom, designed to mate with the hole in the orifice plate below it, it will not function properly.
Respectfully I've been fighting this battle for 40 years, I wish the solution were as simple as ripping a list off the internet. Punch those numbers into eBay and see how many of them look like the picture above. The manufacturers have substituted and cross-referenced thermostats that don't work. They've been doing it for 40 years.
