If not, how are thermostatically-controlled furnaces or air-conditioners treated? Do you have to shut them down before sundown Friday and leave them off until the Sabbath has passed? What if you rent, and have no control over the operation of the system except the thermostat in your quarters? And what if you have no thermostat, and are at the landlord's mercy in this case?
