Question 1

Many ____ use the pressure of refrigerant in a sealed system to sense temperature.&#10;A) differential thermostats&#10;B) programmable thermostats&#10;C) staging thermostats&#10;D) line voltage thermostats

Accepted Answer

Line voltage thermostats often use the pressure of refrigerant in a sealed system to sense temperature, as they are typically used in systems like electric baseboard heating, which can involve direct control of high voltage circuits.

Question 2

The cooling anticipator is a resistive heating element that operates in an opposite sense to the heat anticipator.

Accepted Answer

The cooling anticipator is designed to prevent the cooling system from short cycling by providing a small amount of heat to the thermostat, similar to how the heat anticipator works for heating systems, but in the opposite sense.

Question 3

Some ____ provide extra features, such as antifreeze protection.&#10;A) differential thermostats&#10;B) programmable thermostats&#10;C) staging thermostats&#10;D) line voltage thermostats

Accepted Answer

differential thermostats

Question 4

Many thermostats are designed to permit manual control of the blower fan.

Accepted Answer

Many thermostats have a switch or setting that allows the user to manually control the blower fan, separate from the heating or cooling settings.

Question 5

Dirt around an open-contact thermostat is usually a minor issue.

Accepted Answer

Dirt around an open-contact thermostat can cause it to malfunction by insulating the contacts and preventing proper operation, leading to issues with temperature regulation.

Question 6

The ____ contains only one bimetal strip, which is used to control the action of both sets of contacts.&#10;A) differential thermostat&#10;B) programmable thermostat&#10;C) staging thermostat&#10;D) line voltage thermostat

Accepted Answer

The answer of The ____ contains only one bimetal strip,...

Question 7

Some ____ are operated by integrated circuits (ICS) and permit the temperature to be set to any desired level at any desired time.&#10;A) differential thermostats&#10;B) programmable thermostats&#10;C) step thermostats&#10;D) line voltage thermostats

Accepted Answer

The description fits programmable thermostats, which are operated by integrated circuits and allow for customized temperature settings at specific times. The other options (differential, step, and line voltage thermostats) don't necessarily offer this level of control or use of ICS.

Question 8

One advantage of low-voltage thermostats is that they are safer to use inside the home.

Accepted Answer

Low-voltage thermostats use less than 30 volts of electricity, which is not enough to cause harm to humans. Therefore, they are considered safer to use inside the home compared to high-voltage thermostats.

Question 9

The differential thermostat is used primarily with ____.&#10;A) solar-powered heating systems&#10;B) air-conditioning systems&#10;C) water-heater systems&#10;D) gas-expansion systems

Accepted Answer

Differential thermostat is used primarily with solar-powered heating systems to monitor the temperature difference between the solar collectors and the storage tank.

Question 10

Thermostats are not currently designed to be used for both heating or cooling applications.

Accepted Answer

Thermostats are designed to be used for both heating and cooling applications. They allow users to set a desired temperature for their home or building, and the thermostat will turn on either the heating or cooling system as needed to maintain that temperature.
