We are trying to design an HVAC system for a client and there are many heating zones that would require thermostats. Approximately 30. Our client is very visual and doesn't want to see thermostats all over her house. We toured the Experience Center a couple of months ago and suggested the remote sensors but again, she doesn't want to see these sensors on the walls ( mostly millwork).

Has anyone used an alternative sensor or modified a plate or something so that these can be hidden or more pleasing esthetically? I had to agree with her. They do stand out.
