I've encounter two different hiltons in hot destinations (Utah, La Quinta Ca) that use the verdant thermostats. These are designed to activate based upon motion and heat detection. Good in theory but don't work in practice. The first hotel never got below 80 degrees all night. The second was going to be the same situation but maintenance has agreed to switch to an older thermostat to maintain a constant temperature. I can understand cost savings but these devices don't work.
