The Sheild Maiden- my wonderful wife wanted one of those fancy programmable thermostats to complement our new furnace. So being that it’s hunting season and I spend extra hours in the stand and she never complains about extra chores or running the kids to this and that I bought a nice one- wired it in and nothing- 3 times I tried and nothing- put the old one back on and it worked - so the new one was broken out of the box - took it back to the store got a new one- before I mounted the bracket on the wall I wired this one in and put the battery in and WOW it worked so I unwired it to mount the bracket and dropped it on the title floor and broke the led screen into 1000 pieces- so back to Lowe’s - a 25 mile round trip and got a 3rd thermostat and this one is now installed and working.
My 15 minute project took about 7.5 hours! Ever had those days?
