When I installed an air conditioner in lil' yeti this summer, the short goal was to get it working. The window AC unit had the typical built in thermostat. But those knobs with their number scales are not obvious to tune. Nor well calibrated.
No worries though. My longer goal was a proper wall thermostat. With digital precision and large numbers that're easy to read. Just set the desired temperature and forgetaboutit. I just wasn't impressed with local store offerings. I specifically wanted a simple, non programmable model. Thank goodness for online shopping.
