Thermostat or thermostats for 3 zones of hydronic and forced air
I tried to ask this question at some other places but to my surprise, there was not much response.
Don't think my situation is unique, so hopefully it will help others too.
With the influx of new, smart, wi-fi enabled or networked, large display, etc. thermostats, I would think that there should be a solution to efficiently control 3 zones of hydronic and forced air, together with dehu and circ. Also, I would love to be able to see the reports, track efficiency, usage, etc.
It's a 3 level house: basement (hydronic in slab), 1st and 2nd (hydronic under floor) that also has forced air on each of the floors. Trane furnace is a 2 stage model has variable speed DC fan and electronic air cleaner that can circulate at very low speed, all the time. Also, humidifier and dehu/circulator. Hydronic runs through Lochinvar Knight (1 primary, 3 zone pumps, Taco panel)
The goal would be to have 1 centralized thermostat operating everything with remote sensors or 2 thermostats total (1 for each system) I have not touched controls yet. Likely I will decide on Honeywell Tru Zone for forced air, with motorized supply dampers and bypass return damper. Possibly RedLink too, if necessary.
Important note - I don't plan on running both hydronic and forced air (other than dehu/circ) at the same time. I want to be able to use just 2 stages of forced air heat 3 months a year, 1 stage of forced air cool in the Summer and 1 stage of hydronic in the Winter.
I have looked into Honeywell Prestige IAQ and with proper add-ons, it might be a solution.
Also, read some about Ecobee and it is really impressive. I know I would love it's reporting feature.
Whether it's 1 thermostat that does the whole thing, or 1 thermostat for each system, it needs to have zoning/communicating capabilities. Don't care for hardwired/wireless. I can also see how it's 3 thermostats - 1 for each floor.
Hopefully someone here had experience with similar situation and can point me to the right direction.
I know it can be done with 6 separate thermostats, but won't accept that it's the only good solution in 2013.
