Electric Heat

  • Specify SCR control instead of staged control. There is no cost difference and you get greater control modulation with SCR.
  • Always specify a single point power connection.
  • Specify mercurcy switches instead of magnetic contactors where noise issues are critical.
  • (For an outdoor air unit) consider UL listing of a pieced together system as opposed to a packaged unit.
