Question

What does the AIRFLOW switch do?

A) Monitors blower fans to prove they are in operation
B) Measures the temperature of the air coming from the fans
C) Regulates the speed of the blower fans
D) Controls the lighting in the HVAC system

Answer 1

The AIRFLOW switch controls the speed of the blower fans in an HVAC system, regulating the air circulation and pressure.

Step-by-step explanation:

The AIRFLOW switch is responsible for controlling the speed of the blower fans in an HVAC system. It regulates the amount of air being circulated in the system, ensuring proper ventilation and heating or cooling. When the AIRFLOW switch is adjusted, it alters the speed of the blower fans, which in turn affects the air pressure and flow within the system.
