Carrier Mini Split Wiring Diagram: A Comprehensive Guide

If you are looking to install a Carrier mini split system, it is important to understand the wiring diagram. The wiring diagram provides a roadmap for the installation process and helps ensure that the system is installed correctly. In this article, we will provide a comprehensive guide to the Carrier mini split wiring diagram.

What is a Mini Split System?

A mini split system is a type of HVAC system that consists of an outdoor compressor and an indoor air-handling unit. The two units are connected by a conduit that contains a power cable, refrigerant tubing, and a condensate drain. Mini split systems are ideal for heating and cooling single rooms, and they are often used in homes and businesses that do not have ductwork.

How Does a Mini Split System Work?

A mini split system works by absorbing heat from one place and releasing it into another. The outdoor compressor absorbs heat from the air outside and transfers it to the indoor air-handling unit. The indoor unit then releases the heat into the room. In cooling mode, the process is reversed, and the indoor unit absorbs heat from the room and releases it outside.

Mini split systems are highly efficient because they do not require ductwork. Ductwork can account for up to 30% of energy loss in a traditional HVAC system. With a mini split system, all the energy is directed to the room being heated or cooled, resulting in significant energy savings.

Carrier Mini Split Wiring Diagram

The Carrier mini split system is designed to be easy to install, and the wiring diagram reflects this. The wiring diagram consists of four main components: the outdoor unit, the indoor unit, the power supply, and the control wiring. Let’s look at each component in more detail.

Outdoor Unit Wiring

The outdoor unit wiring consists of the power supply and the refrigerant tubing. The power supply provides electricity to the outdoor unit, and the refrigerant tubing connects the outdoor unit to the indoor unit. The outdoor unit also includes a condensate drain to remove excess moisture.

Indoor Unit Wiring

The indoor unit wiring consists of the power supply, the control wiring, and the air-handling unit. The power supply provides electricity to the indoor unit, and the control wiring connects the indoor unit to the outdoor unit. The air-handling unit is responsible for distributing the heated or cooled air into the room.

Power Supply Wiring

The power supply wiring consists of the electrical system that powers the mini split system. The power supply includes a disconnect switch, a circuit breaker, and wiring that connects the outdoor unit, the indoor unit, and the control wiring.

Control Wiring

The control wiring consists of the thermostat and the wiring that connects the thermostat to the mini split system. The thermostat is the device that controls the temperature in the room.
