Recently had a problem with my aqua stat on my boiler, 2 zones. Had a Pro come in and fix it. Now I was wondering about my thermostats (2) They go down to 50, but I'd rather them go down to forty (I'm retired and broke) I also have a wood stove that I use. I just don't see a need for it to be on most of the time. The tech didn't think it was a very good idea to be flipping the switch on off all the time.
So what I have is the standard Honeywell round units that go down to 50.
I have seen newer ones, I think designed for central air (which I don't have) that go down to 40, is this a swap I could do?
