Description / Applications

The Beckett GeniSysTM 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 having ring rates less than 20 GPH. The GeniSys is used with a suitable cad cell ame sensor to control the oil burner motor, igniter, and optional solenoid valve. It has 24 Vac thermostat terminals (if applicable) compatible with both mechanical and many power stealing thermostats. It can provide interrupted or intermittent duty ignition, and it has a 30 second lockout time on recycle.

Frozen Plumbing and

Water Damage Hazard

If the residence is unattended in severely cold

weather, burner primary control safety lockout, heating system component failures, power outages or other electrical system failures could result in frozen plumbing and water damage

in a matter of hours. For protection, take

preventive actions such as having a security system installed that operates during power outages, senses low temperature and initiates

an effective action. Consult with your heating contractor or a home security agency.
