WarmlyYours EMK120-OT-SGV 120V Underfloor Heating System Kit Operating instructions

  • I've reviewed the user manual for the WarmlyYours NSPIRE Series Thermostats. This document provides detailed wiring instructions for 120V and 240V floor heating systems using a junction box. It also contains information about ensuring the system is grounded and how to connect the thermostat to the junction box. I'm ready to answer any questions you have about the installation or features.
  • Does the floor mat have any polarity?
    What should the wire from the thermostat to the junction box be sized according to?
    What is the maximum power for the floor heating systems?
