Not an Electrician, HVAC Pro or Plumber. Just an average contributor to YouTube. My attempt at wiring 4 Wi-Fi enabled thermostats to One 24V transformer independently from boiler so that my HEAT ONLY system can be shut off during summer months without cutting power to thermostats. Please share your thoughts.... Keep the comments comin' and...... Enjoy!!
