Aux Mini Split Wiring Diagram

Mini split air conditioning systems are gaining popularity in both residential and commercial buildings due to their energy efficiency, easy installation, and flexibility. Among the most popular brands of mini split systems is the Aux mini split. However, before you can enjoy the benefits of this system, proper wiring is necessary. In this article, we will discuss the Aux mini split wiring diagram, including the different components and their functions.

What is a Mini Split System?

A mini split system is a type of air conditioner that does not require ductwork. It consists of two main components: an outdoor unit and an indoor unit. The outdoor unit contains the compressor, while the indoor unit houses the evaporator. The two units are connected by a conduit that houses the refrigerant tubing, power cable, and drainage pipe.

The indoor unit is mounted on the wall or ceiling and is controlled by a remote control or a wired controller. It can be used for both cooling and heating purposes, depending on the model.

Aux Mini Split Components

The Aux mini split system is made up of several components, each with a specific function. These include:

  • Outdoor unit
  • Indoor unit
  • Conduit
  • Power cable
  • Refrigerant tubing
  • Drainage pipe

Outdoor Unit

The outdoor unit is the heart of the Aux mini split system. It houses the compressor, which compresses the refrigerant, and the fan, which cools the condenser coil. The outdoor unit also contains the control board, which regulates the system’s operation.

Indoor Unit

The indoor unit contains the evaporator and the fan that blows the cool air into the room. It also has a filter that traps dust and other particles, keeping the air clean.

Conduit

The conduit is a bundle of cables that connects the indoor and outdoor units. It contains the refrigerant tubing, power cable, and drainage pipe.

Power Cable

The power cable connects the indoor and outdoor units to the electrical supply.

Refrigerant Tubing

The refrigerant tubing transports the refrigerant from the outdoor unit to the indoor unit and back. It is insulated to prevent condensation.

Drainage Pipe

The drainage pipe removes the moisture that is extracted from the indoor air by the evaporator.

The Aux mini split wiring diagram is a schematic representation of the electrical connections between the various components of the system. The diagram includes the following components:

  • Indoor unit
  • Outdoor unit
  • Power supply
  • Control board
  • Remote control

Before wiring the system, make sure to turn off the power supply to avoid injury or damage to the equipment.

Wiring the Indoor Unit

The indoor unit is wired as follows:

Terminal Number Wire Color Connection
1 Red Power supply (L1)
2 Black Power supply (L2)
3 Yellow Compressor
4 Blue Indoor fan
5 White Remote control signal
6 Green/Yellow Ground

The power supply wires (red and black) are connected to the L1 and L2 terminals respectively. The yellow wire is connected to the compressor terminal, while the blue wire is connected to the indoor fan terminal. The white wire is for the remote control signal, while the green/yellow wire is connected to the ground.

Wiring the Outdoor Unit

The outdoor unit is wired as follows:

Terminal Number Wire Color Connection
1 Red Power supply (L1)
2 Black Power supply (L2)
3 Yellow Compressor
4 Brown Capacitor
5 Green/Yellow Ground

The power supply wires (red and black) are connected to the L1 and L2 terminals respectively. The yellow wire is connected to the compressor terminal, while the brown wire is connected to the capacitor terminal. The green/yellow wire is connected to the ground.
