Jewish Festivals: Adjusting Heater

On Jewish festivals, you may adjust a heater with an analog thermostat:
  • UP when running, and
  • DOWN or OFF when not running.
Reason This is due to grama, which is permissible on Jewish festivals (but not on Shabbat).
Note You may not adjust a digital thermostat.
