Reflecting on HVAC Wiring: Understanding RH and RC Terminals

What is the correct way to wire the furnace and AC in a three-wire system?

A) RH to Ac and RC to furnace
B) RH to furnace and RC to Ac
C) Both RH and RC to furnace
D) Both RH and RC to Ac

Answer:

The correct option is B) RH to furnace and RC to Ac.

When it comes to wiring a furnace and AC in a three-wire system, understanding the role of RH and RC terminals is essential. The correct way to wire the system is to connect the furnace to the RH terminal and the AC to the RC terminal.

In a three-wire system, the RH terminal is typically used to provide power to the heating system, while the RC terminal is used for the cooling system. By wiring the furnace to the RH terminal and the AC to the RC terminal, you can independently control the heating and cooling systems.

This configuration allows for efficient operation of both the heating and cooling systems, ensuring optimal performance and comfort in your home. By following the correct wiring setup, you can make sure that your HVAC system works seamlessly to keep your indoor environment comfortable throughout the year.
