I generally like a two thermostat system. Simple, just turn up the one you want. Most people can figure that out.
Neve met my wife have yah?
She likes the look of just one thermostat on the wall since I’ve gone with the aqua stat.
Wish I had known of it 16 years ago. It literally took ALL NIGHT to get that stupid second thermostat hooked up. Only had two wires to start with, so I thought easy cheesy, tape the new multi wire thermostat line to the old and pull it out and things turned to crap from there.
The old wire was actually fastened in a groove in the lathe and plaster behind the paneling. Took a while to get the trim off without breaking any. Found the wire went down to the floor and was in another groove. This groove went off at an angle until it went under the wall?!?!?! Came out on the other side then down thru the floor. Seriously WTF?? They did this to avoid drilling thru a 14x14 beam in the basement. Drill the stupid beam already!!! I had it all apart anyways and the carpet pulled up, I routed the new wire the same.
Of course if I had an Aquastat then, I would still have had to mess with that nightmare later when adding the central air to the house.
