Heating Thermostat Quiz

What happens to the temperature in a conditioned space after the furnace shutdown due to system overshoot?

• The temperature decreases below the set point

• The temperature remains constant

• The temperature fluctuates randomly

• The temperature raises above the set point

What is the term used to describe the phenomenon when ductwork carries built-up heat into conditioned space after furnace shutdown?

• System stability

• System lag

• System overshoot

• System balance

What is the purpose of heat anticipators in thermostats?

• To cool down the thermostat

• To increase the temperature of the conditioned space by 5°F

• To warm the thermostat about 1°F over the conditioned space

• To measure the humidity in the conditioned space

Heat anticipators are designed to:

• Increase system efficiency by running longer

• Turn on the system early

• Help reduce system overshoot

• Maintain a constant temperature without fluctuations

Heat anticipators can be:

• Only fixed

• Only adjustable

• Either fixed or adjustable

• Neither fixed nor adjustable

What component is in series with the switch in a heat anticipator?

• Capacitor

• Small resistance coils

• Inductor

• Transformer

What turns off the system early in a thermostat with a heat anticipator?

• The magnet

• The bimetal strip

• The anticipator

• The C (common) terminal

What is the purpose of cooling anticipators in thermostats?

• To cool down the thermostat during the Off cycle

• To heat up the thermostat during the On cycle

• To warm the thermostat during the Off cycle

• To maintain a constant temperature

Why are cooling anticipators used in thermostats?

• To increase system efficiency

• To prevent system lag

• To indicate temperature levels

• To shut down the system
