A furnace might use an on-delay to:

Select one:

A. Save energy during periods when the space is unoccupied.

B. Prevent the system from cycling between heating and cooling.

C. Prevent thermostat tampering.

D. Avoid blowing cold air into the space when the system starts up.

Answer :

Final answer:

The on delay feature of a furnace is primarily designed to prevent cold air from blowing into the space during startup, enhancing occupant comfort. This feature allows the system to warm up internally before circulating warm air. The correct option is therefore to avoid blowing cold air into the space when starting up.


Explanation:

The Use of On Delay in Furnaces

An on delay in a heating furnace is significant for multiple operational reasons. One of its main purposes is to ensure that there is a controlled heating sequence that prevents cold air from being blown into the living space right when the system starts up. This particular function is essential for enhancing user comfort, especially during the startup phase of the furnace.

Thus, the most suitable answer to the question would be:

  • d. avoid blowing cold air into the space when the system starts up

This on delay feature allows the furnace to warm up internally before any air is circulated into the room, thereby providing a more pleasant experience for the occupants.

In summary, implementing an on delay feature in a furnace is crucial for minimizing discomfort and optimizing performance.
