Daikin IM 1314 User manual

  • Hello! I've reviewed the Installation and Maintenance Manual for the Daikin High Duct Pressure Limit Switch 910339000. This document provides instructions on installing, wiring, and configuring the switch. It also details how to change polarity settings using either the local user interface or ServiceTools software. I'm ready to answer any questions you may have about the switch or its installation.
  • What parts are included with the High Duct Pressure Limit Switch?
    How do I mount the sensor?
    How do I connect the wires from the sensor to the unit?
    How do I change the polarity of the Duct High Limit Switch input using the local user interface?
