Boiler fan center relay wiring diagram is an important aspect of boiler installation and maintenance. It is an electrical component that controls the fan and blower motor in a gas, oil, or electric furnace. Without this component, your boiler will not be able to function optimally.
What is a Boiler Fan Center Relay?
A boiler fan center relay is an electrical component that controls the fan and blower motor in a gas, oil, or electric furnace. It is used to supply power to the fan and blower motor, which in turn helps to circulate warm air throughout your home or building. This component is also responsible for turning off the fan and blower motor when the burner is not in use.
The fan center relay is located on the control panel of your furnace or boiler, and it consists of several components, including a transformer, a relay, and a terminal strip.
The Transformer
The transformer is responsible for converting the voltage of the power source to a lower voltage that is suitable for the control circuit. This allows the relay to be energized by a low-voltage control signal from the thermostat or other control device.
The Relay
The relay is an electromechanical switch that is used to control the flow of electricity to the fan and blower motor. It is activated by a low-voltage control signal from the thermostat or other control device, which causes an electromagnet to pull a set of contacts closed. This allows power to flow to the fan and blower motor, which then circulates warm air throughout your home or building.
The Terminal Strip
The terminal strip is a set of screw terminals that are used to connect the various components of the fan center relay to the control panel of your furnace or boiler. It allows for easy installation and maintenance of the fan center relay.
How to Wire a Boiler Fan Center Relay
Wiring a boiler fan center relay is a straightforward process that can be completed by a qualified electrician or HVAC technician. The following steps will guide you through the process:
Step 1: Turn Off Power
Before beginning any electrical work, it is essential to turn off the power to your furnace or boiler. This can be done at the circuit breaker or by turning off the power switch on the control panel of your furnace or boiler.
Step 2: Locate the Fan Center Relay
The fan center relay is typically located on the control panel of your furnace or boiler. It may be labeled as such, or you may need to refer to the manufacturer’s instructions to locate it.
Step 3: Remove the Cover
Using a screwdriver, remove the cover of the control panel to access the fan center relay.
Step 4: Identify the Wires
Identify the wires that will be connected to the terminal strip on the fan center relay. These wires will typically include a power supply wire, a fan wire, a blower motor wire, and a common wire.
Step 5: Strip the Wires
Using a wire stripper, strip the insulation off the ends of the wires that will be connected to the terminal strip on the fan center relay.
Step 6: Connect the Wires
Connect the wires to the appropriate terminals on the fan center relay. The power supply wire should be connected to the L1 terminal, the fan wire to the F terminal, the blower motor wire to the M terminal, and the common wire to the C terminal. Make sure each wire is securely fastened with a screwdriver.
Step 7: Replace the Cover
Replace the cover of the control panel and turn the power back on to your furnace or boiler.
