Q. Our shul complex (in the U.S.) is very large. We have three main praying areas besides also three large saloons for S’machot and Kiddushin.

Usually during the weekdays to be able to serve energy we use an AI thermostat system that pictures and measures every individual entering the premises and calculates accordingly the amount of heating or cooling necessary during the different seasons of the year. This system provides a great saving in energy charges.

We usually disconnect this system during Shabbat and we use an alternative common thermostat.
However, on the night of Shavuot, since we do have different groups learning all night, we would like to use the AI system, since not only it would provide the right comfortable temperature for the attendant that like the weather always vary, but it would also provide a considerable monetary saving.

Could this AI system be used during the Shavuot Night?

A. Horav Shlomo Miller’s Shlit’a opinion is that it is preferable not to use that system even during Yom Tov.
