My (split level) house requires 3 separate thermostats. I have 3 separate heating zones (boiler baseboard heat) as well as two separate Central AC units that are tied in with two of the 3 thermostats. Here are details:
- Thermostat 1 = Located Upstairs - Heats upstairs, cools upstairs and downstairs for one side of the house.
- Thermostat 2 = Located on the split side of the house - Heats and cools “split” side of the house
- Thermostat 3 = Located Downstairs, below Thermostat 1 - Heats the downstairs area that Thermostat 1 cools.
As you can see, not only do I need 3 thermostats but I also have a unique situation where heating/cooling is handled via different thermostats for one area of my house (downstairs). I am not thrilled about the idea of spending ~$750 for Nest or Ecobee thermostats. I lean more toward using Zwave thermostats that will also allow me to more intelligently use remote sensors to make decisions about which rooms to care more about or use room/area temperature averaging. So, can I ask what you might suggest? It looks like 2Gig makes the popular CT100 Zwave thermostat – I can basically get 3 of those for the price of 1 Nest or Ecobee 3. Are there any other Zwave thermostats I should consider? Here are the possible setups I imagine:
3 Zwave stats – Least expensive option and I can use my already-existing multi-purpose and motion sensors to read temperature throughout the house. This allows me to “care” more about the temperature of certain parts of the house at different times. This is especially important with my upstairs thermostat given that it cools both up and downstairs. It would be nice to be able to tell it to care more about downstairs during the day (right now I have no way to do this, all temp readings are taking upstairs)
3 Ecobee 3 stats – Very expensive, but let’s me use remote sensors and have a thermostat system that can work indepdently of my ST hub. I’m not sure that’s worth $500 more though and the remote sensors are kind of redundant considering I have multis all over the house.
3 Nest stats – Also very expensive and it’s not clear to me how well I could utilize remote sensors to make Nest “smarter” about my particular home setup. And I’m also not sure if Nest’s “learning” interferes with ST or vice-versa? Also hard to believe this would be worth $500 more.
I appreciate any and all thoughts/input! I think I know that Zwave stats are my best option, but I am open to any and all suggestions and would love to hear about anyone that has a similar setup.
