NegFeedBackBasic/SummaryOfHeaterAndCoolerControl
| When room temperature is increased, negative feedback facilitates/inhibits cooler/heater (function). And when the room temperature is decreased, negative feedback facilitates/inhibits heater/cooler (function) |
| When the room temperature is increased（red → blue）negative feedback inhibits the heater (function). | When the room temperature is decreased,（blue → red）negative feedback facilitates the heater (function). |
| When the room temperature is increased（blue → red）negative feedback facilitates the cooler (function). | When the room temperature is decreased,（red → blue）negative feedback inhibits the cooler (function). |
Heaters are used in the winter and coolers are used in the summer (because they are "in the opposite direction", respectively).
Heaters are not used in the summer and coolers are not used in the winter (because they are "in the same direction", respectively).
Challenge Quiz
Because of the increase of room temperature due to summer heat and the effect of cooler heater is in same oppostite direction, negative feedback inhibits the equipment (function).
Because of the decrease of room temperature due to winter chill and the effect of cooler heater is in same oppostite direction, negative feedback facilitates the equipment (function).
Because of the decrease of room temperature due to winter chill and the effect of cooler heater is in same oppostite direction, negative feedback inhibits the equipment (function).
Because of the increase of room temperature due to summer heat and the effect of cooler heater is in same oppostite direction, negative feedback facilitates the equipment (function).
When the room temperature is high, negative feedback inhibits the effect of cooler heater (function).
When the room temperature is low, negative feedback facilitates the effect of cooler heater (function).
When the room temperature is low, negative feedback inhibits the effect of cooler heater (function).
When the room temperature is high, negative feedback facilitates the effect of cooler heater (function).
