Note, cut power to your boiler or furnace before touching the wires. I had learned this the hard way and changed a thermostat without cutting power. While it is low voltage, two wires must have touched and blew a fuse in my furnace causing it to stop working. It cost me $300 for someone to come out and swap what was a basic car fuse.

Yeah 5amp blade style fuse usually. I wish more people knew this.

I’ve saved a lot of people a lot of money (while pocketing a $20 each time) by knowing this.

The worst part is that I talked to someone and explained what happened. They told me they would have to come look at it but it would have to wait until Monday. It was Saturday night and I live in the Buffalo NY area and it was winter. I couldn't get anyone to come look at it so I ended up using a kerosene heater. (the indoor type). When I found out it was a fuse that he could have just told me to replace I was pissed. I understand it was my own fault but it seems like he could have told me over the phone to check that and still have charged me.
