Success... We replaced older Honeywell thermostats with the new ecobee Smart Thermostat LITE. The space is unique, it's an old church converted to a residential space and bar/restaurant. Each thermostat was paired with Ecobee SmartSensors that were mounted in the restaurant. The thermostats were mounted in the residential space. This is not zoning, but helps the restaurant owner make changes on the fly and allows him to observe the bar temp. Next post on this will be an interview with the owner.
