The Economizer Controller can be mounted to sheet metal ductwork. When mounting, note the following:

  • Mount the controller in a position that allows clearance for wiring, servicing, and removal. See Mounting Instructions for required mounting clearances.
  • (For POL224.05) four spacers (M3.5 x L (L ≥10 mm) ) and four M3.5 screws are required. Metal spacers are recommended.
  • (For POL224.00) two No. 6 3/4” self-tapping screws are required.
  • Siemens does not provide screws or spacers with the product. They must be obtained separately.
