A Look at Beckett Genisys Burner Control

Posted by on 10/7/2018 to Articles

As we enter into one of the harshest times of the year it is time that we inspect our furnaces and get them ready for protection to help protect us from the cold conditions winter will bring us. As we check our filters gather the oil we need it is time to inspect our heating equipment for proper operation. One very important piece we cannot be without is the burner control for our systems. The Beckett Genisys burner control is one of the most advanced burner controls of today.

 

The Beckett GeniSys Advanced Burner Control is a 120 Vac primary safety control for residential and light commercial oil burners used in boiler, furnace, and water heater applications. The GeniSys is used with a suitable cad cell flame sensor to control the oil burner motor, igniter and optional solenoid valve. It has 24 Vac thermostat inputs compatible with both on/off and power stealing thermostats. It can provide interrupted or intermittent duty ignition, and has a 15-second lockout time. Model 7505P-152M has a 15-second valve-on delay time and 2-minute motor-off delay time.

 

Beckett GeniSys Advanced Burner Product Details.

 

  • Thermostat and boiler control compatible; technician pump prime mode.
  • Programmable valve-on and motor-off delay; 3 indicator lights for system monitoring and diagnostics.
  • 2 communication ports for adding alarm contact, programming display, and wireless communications
  • Welded Relay Protection W/ Redundant motor relays: Limited reset and limited recycle.
  • Replaces Honeywell R7184P, R7184U, and Carling 60200: 2-minute motor-off delay time. Carlin 60200; 2-minute motor-off delay time.

 

This control is a newer style of the cad cell relay. The time period for ignition can be adjusted and is usually set at about 30 seconds. This control has a safety feature to prevent continued resetting of the primary by the home owner. The unit will only allow 1 reset of the safety. To reset the control, you must hold down the reset for 45 seconds.

 

Sequence of Operation of Oil Burning Furnace

 

On a call for heat, the cad cell relay checks the cad cell to see if it is shorted. If it is above 20,000 ohms, the cad cell relay begins an ignition sequence.

 

First the power is passed from the cad cell relay to the drive motor on the burner assembly and ignition transformer. The motor starts, driving the pump and the combustion blower. As the pump pressure increases, the oil is sprayed into the combustion chamber.


At the same time, the ignition transformer establishes a spark across the electrode spark gap.

The oil is ignited and the light from the flame reaches the cad cell.

 

If the cad cell senses the light from the flame within the time safety period, (40 seconds or less) the burner stays on. As the heat exchanger heats up, the fan switch closes and starts the circulating fan. If at any time, the light from the flame is not sensed by the cad cell, the cad cell relay shuts off the burner and it must be manually reset.

 

As with any type of furnace it is important to follow all maintenance procedures. Be sure to check with your local contractor today to have your furnace tuned up as well as inspected for the upcoming winter season.
