Thank you, Martin, for your prompt response to our concerns. For the past 3 months we'd been struggling to find the proper temperature range needed to maintain a comfortable environment in our great-room area, located 45-plus feet away from the Honeywell thermostat. Thank you for suggesting, and coming out so promptly, to install our new ECOBEE 3 Lite Thermostat with remote sensor! While this response may be a bit premature, we are pleased to say the sensor IS making a difference! We will keep in touch...! Tim & Judy Pope
