⚡ Beckett 7505P452MU GeniSys Advanced 120V Oil Burner Control – 15 Second Lockout

📝 Product Overview

The Beckett GeniSys 7505P452MU is a 120 VAC primary safety control for residential and light commercial oil burners, ideal for boilers, furnaces, and water heaters. It manages the burner’s motor, igniter, and optional solenoid valve using interrupted or intermittent ignition with a 15-second lockout time.

Front-mounted 24 VAC thermostat terminals are compatible with mechanical and power-stealing thermostats (if applicable). For high-moisture environments, a potted version is available as the Beckett GeniSys 7575.

Programmable Pre- and Post-Purge Timings: Use the GeniSys 52082 Contractor Tool or BeckettLink Pro 7652 (sold separately) to adjust valve-on and motor-off delay timings. The control stores the last 15 burner cycles for diagnostics.

Flame Detection: Works with a suitable CAD Cell flame sensor 7006U (sold separately) for full burner control.
