ecobee ecobee3 Programmable Touch-Screen Wi-Fi Thermostat: Maintain a comfortable home with this programmable thermostat, which is Apple® HomeKit-enabled, so you can control the temperature remotely using your compatible device. Home IQ helps you conserve energy.
Q: Hello. I can install 2 ecobee3 in home?
A: Yes I have two installed in my house. You just name each one differently so that you can easily identify each one when you log in
A: The Ecobee can control a humidifier or one additional assessor as long as it is controlled by just a two wire system. The Ecobee does measure humidity in the main unit (not the remote sensors though). I haven't installed mine as the wiring in not easily accessible in the wall (easily).
Q: Will this system work with an Android smartphone? Thanks
A: Yes, I use it on a Samsung Galaxy S6 Active
Q: Wiring
A: yes it does. They supply a connector to take care of this. It's something you have to add in at the furnace, but it's easy to do as long as you have access to the furnace. It's a connector that terminates 5 wires to the furnace with the 4 wires one has.
A: There is a setting for that. You can specify at what humidity (high or low) you wish to be notified.
Q: Is there a monthly fee for Ecobee3
A: No monthly fees. Just make sure it's properly hooked up and that you have available wifi for it to maximize its utility.
A: Two zone heating means two thermostats, with each thermostat controlling their specific zone. An obvious example, one zone for first floor, one zone for second floor. A thermostat will be located on each floor to accurately measure temperature for that zone. Most importantly, when that zone falls below or goes above the temperature threshold, it *powers on* the heating/cooling system and tells the system where to bring the heat/cooling. So, if the second floor needs more heat, the air ducts or hydronic baseboards on the second floor will open up and bring in heat, while nothing happens on the first floor. While I'm not intimately familiar with how the remote sensor works in tandem with the thermostat's sensor, an obvious possibility is that they average their temperature readings and call for heat/cooling so that the temperature hits the set threshold in both locations. However, if you place remote sensors in a different zone, I don't think you'll ever get the cost savings or full benefits of a more balanced temperature since all you'll end up doing is running the wrong zone all the time. Following the example again, if you place a remote sensor on the second floor, with your main thermostat on your first floor, when the second floor requires heat/cooling, the equipment for the first floor turns on, rather than the second floor. You will very slowly, if ever, get the heat/cooling to float up to the second floor.... If your current thermostats are "badly placed" I think you should consider placing the new thermostats in a better location to start with, since the thermostat measures temperature from where it is physically located. So if it's located on an external wall, or in sunlight, those things will affect measurements, causing your system to turn on more frequently because the thermostat is being tricked. For each zone, relocate your thermostat location, then choose a good location for the remote sensor, and I think you will solve your issues.
A: Yes. This is the major advantage of the ecobee3 over other smart thermostats such as the Nest.
