1.
Since the increase in room temperature due to summer heat decrease in room temperature due to winter chill and the effect of a heater are in the same direction, negative feedback facilitates inhibits the heater (function).
2.
Since the increase in room temperature due to the summer heat decrease in room temperature due to the winter chill and the effect of a heater are in the opposite direction, negative feedback facilitates inhbits the heater (function).
3.
