  1. Insteon Thermostat says:

    Because somehow not drilling, nailing or cutting into a floor with known wiring is not obvious…

  2. John Frykman says:

    Houses in most of the US are wired with type NMG (non-metallic with ground) cable. It is not protected where it runs through the wall space other than a plate over the stud which is somewhat resistant to drill-through.

    If the same standard is applied to type NMC cable installations as is being applied to the sensor cable, then the all the wiring in residential units must be torn out and replaced with some other type of wiring.

    This is indeed idiotic.

  3. “Thermostats included in the recall are connected to 208-Volt or 240-Volt power supplies” really?
