Do these come in a vertical product?
Skinny space. Thanks
All the electronic ones I’ve seen are all landscape format, you probably need to stick with the old mechanical types to fit the space, unless you want to relocate it to a regular wall.
Does anyone know how many wires this thermostat has? There are two different types, 3 and 4 wire.
I don’t know, but it looks like it’s sold on Amazon. One of the reviews included a shot of the back of the unit, hope that helps! https://www.amazon.com/Honeywell-RTH221B1021-E1-Programmable-Thermostat/dp/B0088A5X5G?th=1
are these made in USA
According to Amazon, it’s made in China.

The installation manual can be seen from that link. The refurbished unit doesn’t come with the full installation manual, just an operator manual, so you have to download it yourself.
It’s got connections for B O G Y W R Rc, with contact closures provided for controlling heating (W/B), cooling (Y/O), and fan (G).
