resideo HE150 Installation guide

  • Hello! I've reviewed the installation addendum for Resideo humidifiers, including models HE150, HE250, HE300, and humidistat H8908. This document provides detailed wiring configurations for various setups, such as humidifying with a heat or fan call, and using intelligent controls. I'm here to help, so please feel free to ask any questions you have about these devices.
  • What transformer is used for HE150/HE250 models?
    What power source does HE300 model use?
    When to connect G to humidify?
    When to connect W to humidify?
