The Mars 10586 is a widely used HVAC fan control that helps regulate the speed of the blower motor for heating and cooling systems. In this article, we will explore the wiring diagram for the Mars 10586 and provide a step-by-step guide on how to wire it correctly.
What is a Mars 10586 Fan Control?
A Mars 10586 fan control is a device that helps regulate the speed of the blower motor in an HVAC unit. It is designed to help reduce the noise levels produced by the fan motor, increase efficiency, and improve overall performance.
The Mars 10586 fan control can be used in a variety of heating and cooling systems, including furnaces, air conditioning units, and heat pumps.
How does the Mars 10586 fan control work?
The Mars 10586 fan control works by adjusting the output voltage to the blower motor. The output voltage is controlled by a triac, which allows for precise adjustment of the fan speed.
The fan control also includes a built-in delay timer that helps prevent the fan from turning on and off rapidly, which can cause excess wear and tear on the fan motor and reduce its lifespan.
Wiring Diagram for the Mars 10586 Fan Control
Before you begin wiring the Mars 10586 fan control, it is important to ensure that you have the correct tools and materials. You will need:
| Tools | Materials |
|---|---|
| Screwdriver | Mars 10586 fan control |
| Wire strippers | Wire nuts |
| Wire cutters | Electrical tape |
| Multimeter | Wire connectors |
Once you have gathered the necessary tools and materials, you can proceed with wiring the Mars 10586 fan control. Follow these steps:
Step 1: Turn off Power to the HVAC System
Before beginning any electrical work, it is important to turn off the power to the HVAC system. This can be done by switching off the circuit breaker or disconnecting the power supply to the unit.
Step 2: Remove the Access Panel
Remove the access panel to gain access to the wiring connections for the blower motor. Depending on the HVAC system, this may require unscrewing or lifting the panel off its hinges.
Step 3: Locate the Wiring Connections for the Blower Motor
The wiring connections for the blower motor will typically be located near the blower housing. They will consist of several wires that are connected to the blower motor and the control board.
Step 4: Identify the Wires
Using a multimeter or a wiring diagram, identify the wires connected to the blower motor and the control board. The wires for the blower motor will typically be labeled as high speed, medium speed, and low speed.
The wires for the control board will typically include a neutral wire, a ground wire, and a wire that is connected to the motor speed controller.
Step 5: Wire the Mars 10586 Fan Control
Wire the Mars 10586 fan control by connecting the wires from the blower motor and the control board to the appropriate terminals on the fan control.
The wires for the blower motor should be connected to the terminals labeled LO, MED, and HI on the fan control. The wire for the control board should be connected to the terminal labeled MOTOR.
Step 6: Test the System
Once the fan control has been wired, turn on the power to the HVAC system and test the blower motor to ensure that it is running at the correct speed.
