Sorry for the delay in doing this review. I just had it installed 04/27/2021. This is a replacement for an no longer available model installed December 2015. That unit's circuit board died due to overload of current (I suppose) from a severe lightening storm. This new unit is very attractive and I do like the touch screen capability to program the required settings. The floor mat works great, and so does this thermostat. I highly recommend this programable thermostat. I ordered this new 2021 unit via email. I contacted WarmYourFloor via telephone to inquire whether the 2015 model was available to purchase, but was told it no longer is available.
