Does anyone have experience with an Ecobee thermostat controlling a WaterFurnace unit? Owners? Installers? I have owned a WaterFurnace Series 5 for nine years now. It has worked reasonably well with the first generation Ecobee SmartThermostat model (EB-STAT-02). There was a struggle to get my HVAC guys to accept the configuration back in 2012, as WF had no smart thermostats yet. I ended up being the main researcher for technical issues and after some trial/error, we got the system running smoothly. (Eden Energy Equipment out of Ontario Canada was a huge help even though I was 2000 miles away. Sadly, that resource seems to have discontinued with Ecobee products.) I briefly considered the WF Symphony upgrade, but fell out of my chair at the price tag and never looked back. Unfortunately, problems have arisen just recently with my system. A maintenance visit to confirm that the WF was working appropriately points to problems with the aging Ecobee. I just ordered an Ecobee SmartThermostat with VoiceControl (EB-STATE5-01) and will install it soon. I am pleased that Ecobee has expanded their technical resources for geothermal units specifically, when before it was such a gray area. In the meantime, dose anyone have this model installed or been the professional that set one up? Any comments? Peace, Dr. Z.
