Welcome to the forums.

Not sure exactly which thermostat would be the best replacement for you. I see the T8411 uses two separate terminals for hot and cold operation as opposed to the one that most use now.

I'd like to see how your current stat is wired. Remove it from the base, take a picture and post it here for us..... How-to-insert-pictures.
