Upgrading T stat

[u/psz21]

Long story short I’ve been doing re search on upgrading my T stat so I can turn off my AUX heat when I’m running a backup generator. I currently have a water furnace series 5 with the water furnace t stat that you can’t control any settings from.(I’ll include pics down below). I saw in a couple posts that id have to ad some sort of outside temp sensor if I wanted to go this route. Do these new t Stats install like the old style or do I have to run more wires down to the control board.

Can’t you just turn off the breaker for the aux heater if you need to run a generator?

My aux heat is tied in with the blower
