Introduction
Fans are a necessary component in many electrical systems. They are used for cooling purposes and to prevent overheating. In order to control the operation of a fan, a relay is required. A relay is an electrical switch that is operated by an electromagnet. The use of relays in a fan setup allows for the control of the fan at different speeds and also allows for the fan to be turned on and off as required.
In this article, we will discuss the wiring diagram for a 3 relay fan setup. This setup is commonly used in systems that require more than one fan.
Wiring Diagram
The wiring diagram for the 3 relay fan setup is as follows:
| Wire Color | Description |
|---|---|
| Red | Main power supply |
| Black | Ground |
| Green | Relay 1 control wire |
| Yellow | Relay 2 control wire |
| Blue | Relay 3 control wire |
| White | Fan motor positive supply |
| Brown | Thermostat positive supply |
| Orange | Thermostat control wire |
The wiring diagram shows the various wires and their functions in the setup. The red wire is the main power supply, which provides power to the entire system. The black wire is the ground wire, which is used to complete the electrical circuit. The green, yellow, and blue wires are the control wires for the three relays. These wires are used to turn the relays on and off as required.
The white wire is the positive supply wire for the fan motor. This wire provides power to the fan motor in order to make it operate. The brown wire is the positive supply wire for the thermostat. This wire provides power to the thermostat, which is used to control the temperature in the system. The orange wire is the control wire for the thermostat. This wire is used to turn the thermostat on and off as required.
FAQ
