Oil Primary Controls

R7284 Interrupted Electronic Oil Primary Control

• Digital, universal primary control, engineered to address and anticipate
  the most common industry needs
• Provides line voltage, safety rated, interrupted and intermittent ignition
  oil primary control for residential oil fired burners used in boilers,
  forced air furnaces and water heaters
• Used with a cad cell flame sensor operates an oil burner, spark igniter,
  and optional oil valve
• Every setting and diagnostic is user-friendly displayed and
  available in multiple languages
• Works with a low voltage and optional high voltage thermostat
• The primary controls fuel oil, senses flame, controls ignition spark
  (either interrupted or intermittent) and notifies through the EnviraCOM
  bus a remote alarm circuit when in lockout
• Can be used with both hydronic and forced air systems
• When used with hydronic systems, line voltage switching Aquastat® Controllers
  normally provide for the starting and stopping of the combustion sequences
• With forced air systems, both mechanical and electronic low voltage thermostats
  control the starting and stopping of the combustion process
• Mounts in junction box on main burner
• Temperature range: -40° to 147°F (-40° to 64°C)
• Electrical connections: burner motor, oil valve, ignition, cad cell, limit, thermostat, alarm
