Can you have 2 thermostats in one house because of 2 furnaces?

my thought is yes because each one will function separate of each other and have different MAC Addresses

If your internet signal us strong enough there is no technical reason why you couldn't have two in the same house.

I would thinks so since you assign an ip address to each one. They have some software too for comtrolling door locks, etc.

I just talked to my furnace tech about this, and he said it's fine to get a single stage thermostat for a 2 stage furnace. The reason is that a 2 stage furnace will automatically run on low for a few minutes then go to high. At the moment we have a single stage thermostat and our furnace does just that. If you get a 2 stage thermostat it might override the furnace and go right to high for instance - or run the low stage for longer, but you don't need it for your furnace to do its own 2 stages.

Yes, you can only use one if you wish, the other one could or could not be used for other temp readings ie in you fridge or perhaps use it to monitor temp outside of the house.

While it is possible to put two Stiebel Eltron CK 15E on a line to share a thermostat, it is not a good idea. Best if each one has its own thermostat for a number of reasons. Hope that helps.

Yes, in conjunction with the Honeywell HZ432 panel and wireless adapter you can have up to 4 wireless zones installed. They will not interfere with each other - each gets set as a seperate zone.

If all 3 levels are heated by the same furnace one unit should do the trick. Just put the sensor in the zone that receives the least heat. However, if each level is served by its own furnace you will need 3 units.

Yes. Select one 9000 BTU Indoor unit for the bedroom and a 12000 BTU Indoor unit for the sun room. On a dual system for best matching.

Yes, but there's a way to avoid this extra cost if you have a gas/oil/propane furnace by switching the C wire for the G wire, both at the thermostat and the HVAC. The only drawback is that you won't be able to turn on/off the fan on demand, but the HVAC controls this automatically and I really don't change the fan settings anyway. Here's the "secret" tutorial to do it: http://www.youtube.com/watch?v=BftoUCnKYls

If you're only controlling heater, then use a 2 wire heat only unit like this one:Heat Only Digital Non-Programmable Thermostat

Not sure!! Try this #800-468-1502 Or this website http://DIYthermostats.honeywell.com I"m guessing but a 2 wire system would only be for heating OR cooling not both.

P.S. You can power it off the R & C terminals where your thermostat ties into your furnace if your thermostat is 24V.

Depends on how you keep your thermostat. If you keep a constant 80° in your house you would be okay. But if you live up north, you probably don't and would need at least two of these.

I answered this from mu iPhone, but I'd like to add something. If the area of the heated area is so large that two thermostats are need, I would suggest splitting the areas and have one thermostat for each area. There is no way you can have two thermostats for the same floor. That would be like having two thermostats for the same furnace. :)

Yes, using the Web App you can change the mode from/to Auto, Heat, Cool, Fan, or Off. Note your furnace will still have power to it, the thermostat will not call for heat, cool, etc. So if there is a malfunction with the furnace, you can not remotely stop line power to the furnace.

If you're asking whether one unit can independantly control two separate heating/cooling zones, the answer is no. For two zones, you'll need to purchase two thermostats. I've just completed a two zone installation in my home this weekend. Be aware that, unlike the Nest, these units do not communicate in any way with each other. Thus, for instance, when unit one is heating it will show both heat and fan active, but the other unit will show both as idle.

I do not think so. This unit has a direct plug that controls both heating and AC. I would suggest you check directly with Honeywell on this one. You are looking for a single function thermostats just to control heat.

No need for anything else as long as your system is redlink enabled already. If you only have one thermostat the PCC (http://amzn.com/B004MH0S40) will just display a duplicate of what is on the thermostat. The PCC is nice to consolidate information when you have multiple thermostats in one home.
