ICM Controls ACC-RT104 Application/Install Guide

  • Hello! I've reviewed the installation instructions for the ICM Controls RT103/RT104 Remote Sensor. This document details how to properly mount and connect the sensor to your thermostat, including specific wiring instructions and steps for disabling the main sensor on certain thermostat models. I'm ready to answer any questions you have about these instructions.
  • What tool is needed to remove the sensor housing cover?
    Where should the remote sensor be mounted?
    What type of wire is required for connecting the sensor to the thermostat?
