>>They leave the lid closed all week until Sundays, with the heating set to 56 all week (unless there's an event). There is no bottom cover. They have reported to me the low-water light was blinking occasionally, but I'm pretty sure they keep up with watering the piano. 56 is pretty severe. Since you have a little history now and you are still seeing instability, I'd definitely recommend that they install a Jansen cover. Explain that the piano is not staying as stable as it needs to be and the severity of the environment is dictating the additional step of adding a cover. Dean
